After doing some research on the web for laying out spiral stairs I was ready to map the steps out. My stairs would have a rise of 8". The treads would be tapered from 4" where they will be mortised into the tree trunk to 12" wide at the outside end. They will be cut out of 2" thick Oak from the tree tops and other logs in the woods. A pattern was made on paper and wrapped around the trunk where the individual steps were marked and twenty-four 3/16" holes drilled. </span></div><div class="separator" style="clear: both; text-align: center;"><span style="text-align: left;"><br /></span></div><div class="separator" style="clear: both; text-align: center;"><span style="text-align: left;"><div class="separator" style="clear: both; text-align: center;"><a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEhs0XJzm_-lkWFiObhEDLNkdyLsl3Y7yIZ9siFaFu7oQo4Mo0MxAa7CQzMoYndGg_LQXlylytSkZVhxlP2_5v8LCHhWmAJ0tanij8Iw3xP8IxJp-_uJcxBTQV7N-nxmAdEg_Iveo3eBhKazC_W6fU4bDk8ph-UL1Ex_8z0lkDjD7gSPQJK7LsRMT58/s4608/IMG_4269.jpg" imageanchor="1" style="margin-left: 1em; margin-right: 1em;"><img border="0" data-original-height="3456" data-original-width="4608" height="240" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEhs0XJzm_-lkWFiObhEDLNkdyLsl3Y7yIZ9siFaFu7oQo4Mo0MxAa7CQzMoYndGg_LQXlylytSkZVhxlP2_5v8LCHhWmAJ0tanij8Iw3xP8IxJp-_uJcxBTQV7N-nxmAdEg_Iveo3eBhKazC_W6fU4bDk8ph-UL1Ex_8z0lkDjD7gSPQJK7LsRMT58/s320/IMG_4269.jpg" width="320" /></a></div><div class="separator" style="clear: both; text-align: left;">The 24 model stair treads are cut out of cardboard.</div><div class="separator" style="clear: both; text-align: left;"><br /></div><div class="separator" style="clear: both; text-align: center;"><span style="text-align: left;"><br /></span></div><div class="separator" style="clear: both; text-align: left;"><a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEg3Itkxx0IA2v4SRagW36wSImDYTWWdAV0DZJYg43qcLeztGPLPdj_8AMMTxT2X3PCXbLkiu-IIJFawIwzYPrNq2cctYvgJmCJ4NZUAOMRLYIHGOi-C_QeDpFQRWjDk82_6S0jlIAN0IQnJ_u2QaLufCtkqWfiIniSC5pu3GqOK9n6HW5G5oU65kwY/s4608/IMG_4270.jpg" imageanchor="1" style="margin-left: 1em; margin-right: 1em;"><img border="0" data-original-height="3456" data-original-width="4608" height="240" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEg3Itkxx0IA2v4SRagW36wSImDYTWWdAV0DZJYg43qcLeztGPLPdj_8AMMTxT2X3PCXbLkiu-IIJFawIwzYPrNq2cctYvgJmCJ4NZUAOMRLYIHGOi-C_QeDpFQRWjDk82_6S0jlIAN0IQnJ_u2QaLufCtkqWfiIniSC5pu3GqOK9n6HW5G5oU65kwY/s320/IMG_4270.jpg" width="320" /></a><span style="text-align: left;">I hot glued the treads to chop sticks because the tapered end fit and held each step very nicely in the 3/16" diameter drilled holes.

Any knee braces will also have to stay out of the stairway. Lastly the 4 by 6's cannot cover up any of the holes for the 1/2" diameter stair hanger rods.

There's re-bar stop at the bottom of each stair tread.

First I designed and built a simple load tester. I modified and added a pressure gauge to my bottle jack. Each landscape timber was positioned in the fixture so the bottle jack could jack it up 1 inch from straight at rest. At this point I recorded the PSI reading on the gauge. The readings ranged from a low of 100 to a high of 600. The lower the PSI reading the weaker the timber's bending strength. Those were used for the lateral cross pieces.</div><div class="separator" style="clear: both; text-align: left;"><br /></div><div class="separator" style="clear: both; text-align: left;"><div class="separator" style="clear: both; text-align: center;"><a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEiiOr5eQATGDkmmWtmli3k3efeifWQh5yywvcZEfF0oQdj046UmbuMZ7qF7shdYF4F8qR5FyYL3gOrk8sSUAXdFNGHgVMgVQJiyCpTkwtO8qiHwgT6WGxXso5Fz_sxk7momoVdkKRxh8dve1V6-hJcmWouk2XdmMQE-YiFqNikCvS3Ke75gM3ZPLjE/s4608/IMG_4147.jpg" imageanchor="1" style="margin-left: 1em; margin-right: 1em;"><img border="0" data-original-height="3456" data-original-width="4608" height="240" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEiiOr5eQATGDkmmWtmli3k3efeifWQh5yywvcZEfF0oQdj046UmbuMZ7qF7shdYF4F8qR5FyYL3gOrk8sSUAXdFNGHgVMgVQJiyCpTkwtO8qiHwgT6WGxXso5Fz_sxk7momoVdkKRxh8dve1V6-hJcmWouk2XdmMQE-YiFqNikCvS3Ke75gM3ZPLjE/s320/IMG_4147.jpg" width="320" /></a></div>The process starts like this.

The bridge is assembled from the center out. The section on the right in the picture will end up being the center of the bridge and the two lateral cross pieces will then be level. <div><br /></div><div><div class="separator" style="clear: both; text-align: center;"><a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEhMW7cHU9RwfhduuTNOKU0661r3oatFBXKG0gCGswNTo2vqezZJsh3QvHBmVIAB-rz3mVVyxS0eyd0A6lCAiozumKdYUnL-pmQWObYCJUKKsRbkM-XwHM12_QEJ0TZ8l2_VMQ3WU85D5dFbLwqjA4IM3PQSPQW-tXNxwPf6gS7hlOglIXKePjG2aJQ/s4608/IMG_4183.jpg" imageanchor="1" style="margin-left: 1em; margin-right: 1em;"><img border="0" data-original-height="3456" data-original-width="4608" height="240" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEhMW7cHU9RwfhduuTNOKU0661r3oatFBXKG0gCGswNTo2vqezZJsh3QvHBmVIAB-rz3mVVyxS0eyd0A6lCAiozumKdYUnL-pmQWObYCJUKKsRbkM-XwHM12_QEJ0TZ8l2_VMQ3WU85D5dFbLwqjA4IM3PQSPQW-tXNxwPf6gS7hlOglIXKePjG2aJQ/s320/IMG_4183.jpg" width="320" /></a></div>This picture of the finished bridge might help you get the sequence of steps in mind better.

The model generator was mounted, raised and tested for output lighting a small LED.<div><br /></div><div class="separator" style="clear: both; text-align: center;"><a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEhuolll9zUeoFbKWDepkVcupcLcQYLHsTc-mvyh0GqLmmUqsLQbG5v3IN9hnZd5efPxAbzZPO5JiPfjAYKsmLvkl7I7mPLbBT8niKOwLm8HThUfTtpqjNJc3-ihR0jJvhWMP1GZJKRvynsPpdiEMFcOBfiYlTCyDeVRA-0XazNCMFtPgk0UxmArraw/s4608/IMG_3874.jpg" imageanchor="1" style="margin-left: 1em; margin-right: 1em;"><img border="0" data-original-height="4608" data-original-width="3456" height="320" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEhuolll9zUeoFbKWDepkVcupcLcQYLHsTc-mvyh0GqLmmUqsLQbG5v3IN9hnZd5efPxAbzZPO5JiPfjAYKsmLvkl7I7mPLbBT8niKOwLm8HThUfTtpqjNJc3-ihR0jJvhWMP1GZJKRvynsPpdiEMFcOBfiYlTCyDeVRA-0XazNCMFtPgk0UxmArraw/s320/IMG_3874.jpg" width="240" /></a></div>At the end of the hour each group had gone through the process twice. Once without the turbine to prove out the cable system and make any adjustments before mounting the generator to the tower.

After seeing what the College Wind Challenge teams put together for the 2022 challenge in San Antonio, TX my wheels began to turn. </p><p>The Darlington and Mauston KidWind teams continue to learn and grow finishing among the top 3 high school teams again this year. So it is my hope that they will take on the task of designing, building and testing a wind turbine for the 2023 KidWind Challenge year that will have blades that change pitch as the speed of the rotor picks up. </p><p>The goal here is to provide the teams with a proof of concept to study and improve upon. Words just cannot do these ideas justice. Like the saying goes, "I hear it I forget. I see it I remember. I do it I understand."</p><p><span style="color: red;">DESIGN #1 Basic mechanical system 101</span></p><div class="separator" style="clear: both; text-align: center;"><a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEhBGm0dR9bmuslKsaIQklo2_cufNhb5F96OuU_3jLxKTuwjME-C3EcF7q-v3L3FIKBMvmupbVJbZ0qk5u0eqJ1AHm4NF31ro6QPP0zUTK-KjvS3ZBjnuUyWVOmpb2CovUpyUV3Hmwz4m-A8X8HItkdrqVDxIrZ1hvHkydDulEc_ebmXM25nrF0ZKug/s4608/IMG_4079.jpg" imageanchor="1" style="margin-left: 1em; margin-right: 1em;"><img border="0" data-original-height="3456" data-original-width="4608" height="240" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEhBGm0dR9bmuslKsaIQklo2_cufNhb5F96OuU_3jLxKTuwjME-C3EcF7q-v3L3FIKBMvmupbVJbZ0qk5u0eqJ1AHm4NF31ro6QPP0zUTK-KjvS3ZBjnuUyWVOmpb2CovUpyUV3Hmwz4m-A8X8HItkdrqVDxIrZ1hvHkydDulEc_ebmXM25nrF0ZKug/s320/IMG_4079.jpg" width="320" /></a></div>First up is this model.

There are some complicated DPDT relays and switches needed to be able to reverse the polarity to run the motors backwards to get the blades to return to the 45 degree pitch. Overall the self contained system proved it's self when placed in the wind tunnel with blades held at 45 degree pitch the maximum rpm was about 150. When the system was placed in the wind tunnel and operated so the pitch changed the rpm went up to 400. Very happy with this first design. The major problem was that the DC gear motors turned at slightly different speeds and this caused the pitch from blade to blade to vary. Plus no way to attach a generator.</div><div><br /></div><div><span style="color: red;">DESIGN #2 The NEMA Stepper Motor control with Arduino and Rotary Encoder. </span></div><div><span style="color: red;"><br /></span></div><div><div class="separator" style="clear: both; text-align: center;"><a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEi-FSwMspmqSGJhTru-iuZEfF9FzziNZRsJ3SrDRYMAUUKyfgMj0n4kJrlJNv4kZFEPsDepx1Ksy7iXR_9dTYhrMihWuyikkXj0g1kYd6TeddfYyuICYT-X0hzNTb8QR9tmPNnn8ddHgKKRntLehoCZHUxFi7JfpIdwi6wvOY9dGKDFnN3QPPQz774/s4608/IMG_4092.jpg" imageanchor="1" style="margin-left: 1em; margin-right: 1em;"><img border="0" data-original-height="3456" data-original-width="4608" height="240" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEi-FSwMspmqSGJhTru-iuZEfF9FzziNZRsJ3SrDRYMAUUKyfgMj0n4kJrlJNv4kZFEPsDepx1Ksy7iXR_9dTYhrMihWuyikkXj0g1kYd6TeddfYyuICYT-X0hzNTb8QR9tmPNnn8ddHgKKRntLehoCZHUxFi7JfpIdwi6wvOY9dGKDFnN3QPPQz774/s320/IMG_4092.jpg" width="320" /></a></div><div>This was going to be a trimmed down model with the center threaded rod bring turned causing the nut on the end of the rod to move toward the front of the turbine and change the pitch of the blades.

My fix was to attach a 32 tooth KidWind gear to the shaft and drive it with an 8 tooth pinion that I 3D printed to fit the stepper motor shaft. You can see the stepper motor at the bottom of the Nacelle. The drive mechanics worked well.</div><div><br /></div><div class="separator" style="clear: both; text-align: center;"><a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEhLkHz7NAv74P2n5biBlj-mNPkkjOjYVHkv5WceNE81ohEAOYDpiKJY0Au3iWFSzvg9VcSswE2XitqDQgaoeYViZOji-UdWMgNwJrtYrwjFIMqQzSwXk62NuG1cGZGv2uSRpQlQoKIM67lVdsj2kUV9eWAVwQEm1uHZN9-FpzvnBC4hkkZPJibdYgg/s4608/IMG_4090.jpg" imageanchor="1" style="margin-left: 1em; margin-right: 1em;"><img border="0" data-original-height="4608" data-original-width="3456" height="320" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEhLkHz7NAv74P2n5biBlj-mNPkkjOjYVHkv5WceNE81ohEAOYDpiKJY0Au3iWFSzvg9VcSswE2XitqDQgaoeYViZOji-UdWMgNwJrtYrwjFIMqQzSwXk62NuG1cGZGv2uSRpQlQoKIM67lVdsj2kUV9eWAVwQEm1uHZN9-FpzvnBC4hkkZPJibdYgg/s320/IMG_4090.jpg" width="240" /></a></div>Now the plan was that I wanted to place all the electronics and power supply into the Nacelle for one nice neat package. I did manage to place the Arduino board, Stepper Motor Control board and Rotary Encoder in the Nacelle. However the 5 volt power for the Arduino board and 12 volt power for the Stepper motor would not fit. Also there was no way to attach a generator to this system. But the system worked well. The blades would be placed at a 3-5 degree pitch angle. Then the system turned on and the Rotary Encoder turned the correct number of turns to make the stepper motor rotate the threaded rod and move the nut until the blades were at a 45 degree pitch. Now the wind tunnel would be turned on and when up to speed the Rotary Encoder button be pushed sending a signal to the Arduino board to return the stepper motor to the position it started at. This would be the 3-5 degree pitch for highest rpm. Took a bit of new learning to get the Arduino and programming code to work but all is good. Now to just solve the problem of being able to get it to drive a generator and produce some electricity.</div><div><br /></div><div><span style="color: red;">DESIGN #3 Thinking like the real 2MW Vestas</span> </div><div><br /></div><div class="separator" style="clear: both; text-align: center;"><a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEj79Vx7ZJlMvWCnjP6-Wv2WEMUhpco_wT3WBy9XzQf1eixrB3LTXFzaOTPEI_0ksgI6kfStuNpIfMmUL5wRbarK5POMvdYz9HFV9dZdUgYfmU2h1nIbMaCga1iYY2KXz23xwf50tIPS4SRKq9Np-ZVZxlI0o2bMHWpYl4tD7uE4Q5kT_ct9JZnMleM/s4608/IMG_4098.jpg" imageanchor="1" style="margin-left: 1em; margin-right: 1em;"><img border="0" data-original-height="3456" data-original-width="4608" height="240" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEj79Vx7ZJlMvWCnjP6-Wv2WEMUhpco_wT3WBy9XzQf1eixrB3LTXFzaOTPEI_0ksgI6kfStuNpIfMmUL5wRbarK5POMvdYz9HFV9dZdUgYfmU2h1nIbMaCga1iYY2KXz23xwf50tIPS4SRKq9Np-ZVZxlI0o2bMHWpYl4tD7uE4Q5kT_ct9JZnMleM/s320/IMG_4098.jpg" width="320" /></a></div>OK so the stepper motor needed to be in the nose of the rotor. And the linkage rods reversed. A 1/2 - 20 NF threaded rod with a nut was used as before to provide the motion to the linkage arms. The blades are mounted to the white gear (just used the gear I had instead of cutting a blank disk) and allowed to rotate to change their pitch. Now just behind the white gear is the slip ring assembly where the 2 signal and 2 power lead connections are made. All of this rotates at the speed of the blade rotor, just like a Vestas turbine!<div><br /></div><div><div class="separator" style="clear: both; text-align: center;"><a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEiMOinQ2SI3YbGWomUQjAxsC-HEcH7lb3n2mwwGyhr9-5UeYhvPb3VF66b4KQoud6c_EVKvA8wa7eYUbOEA6y5KJ3GmWdD4j9SFunJzThtCl9bnNn_XNKj5h3XbNCaLDToSuJZNtLI-ybelo5e5hOJXbdB5VgfrGC5MOyqrsxEmMcYFisbNWKTKljk/s4608/IMG_4100.jpg" imageanchor="1" style="margin-left: 1em; margin-right: 1em;"><img border="0" data-original-height="3456" data-original-width="4608" height="240" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEiMOinQ2SI3YbGWomUQjAxsC-HEcH7lb3n2mwwGyhr9-5UeYhvPb3VF66b4KQoud6c_EVKvA8wa7eYUbOEA6y5KJ3GmWdD4j9SFunJzThtCl9bnNn_XNKj5h3XbNCaLDToSuJZNtLI-ybelo5e5hOJXbdB5VgfrGC5MOyqrsxEmMcYFisbNWKTKljk/s320/IMG_4100.jpg" width="320" /></a></div>Now this 1/2 - 20 NF rod is held in some nice bearings for support (not like the piece of 2x4 in the model). Then a coupler does the job between the rotor and the 1:25 gearbox and 20 watt generator. Using a 5" diameter PVC pipe for the Nacelle the electronics and power supplies should fit nicely.</div><div><br /></div><div>So now the next step is to learn how to get the data from the rpm sensor to be used to determine the pitch of the blades and control rotor speed and electrical output. No small task but a good learning opportunity for KidWind teams that want to blow away the judges in 2023. <br /> <br /><div><br /><div><br /></div><span style="color: red;"><br /></span></div><div><br /></div><div><br /> </div></div>Dickhttp://www.blogger.com/profile/13870935149581761539noreply@blogger.com0tag:blogger.com,1999:blog-5754440625977916703.post-30626653952398501652022-03-02T13:41:00.000-08:002022-03-02T13:41:01.378-08:00KidWind, Students and Maple Syrup<p> OK this post is going to be about some serious fun.</p><p></p><div class="separator" style="clear: both; text-align: center;"><a href="https://blogger.googleusercontent.com/img/a/AVvXsEiCbk8UdVunTBZz_0lz-9beUWR7r4qqsQ9mtLiSJVs1TYJFbx02rdt9Vd0moOzy-q0GYJ3L0Ni4K1bpksO6ScesOQDgDW8RHwUwr_chqJLb5hJjhNpJErLFoFa3M4xzIygZu8URVdddfzuDsbqt8lT9tQ_2MICHlE0akK08ymKd_Bu_R0dUTSGUOo0=s4608" style="margin-left: 1em; margin-right: 1em;"><img border="0" data-original-height="3456" data-original-width="4608" height="240" src="https://blogger.googleusercontent.com/img/a/AVvXsEiCbk8UdVunTBZz_0lz-9beUWR7r4qqsQ9mtLiSJVs1TYJFbx02rdt9Vd0moOzy-q0GYJ3L0Ni4K1bpksO6ScesOQDgDW8RHwUwr_chqJLb5hJjhNpJErLFoFa3M4xzIygZu8URVdddfzuDsbqt8lT9tQ_2MICHlE0akK08ymKd_Bu_R0dUTSGUOo0=s320" width="320" /></a></div><div class="separator" style="clear: both; text-align: left;">Darlington Quilt Block KidWind team making their presentation to the Manage and staff at EDP Renewables Quilt Block wind farm in Darlington.

They also went on to complete two Instant Challenges. These were a surprise test to correctly rig a gin pole and make a guyed tower raising in 30 minutes. Then they had to design a wind farm layout for highest production and lowest cost. They also got to listen to presentations from people in the wind industry and visit displays set up by local utility companies and vocational schools.

This boiler will hold one gallon of sap and the feeding system hooked up to the 30 gallon sap supply will keep that level as the boiling takes place. I tested out the system today using only two gallons of sap! Look closely and you can see the 4 ounces of finished maple syrup in the pint fruit jar sitting on the white cloth. The orange hydrometer box is pointing to it. It took two hours of boiling and consumed about 3/4 pounds of propane.<div><br /></div><div class="separator" style="clear: both; text-align: center;"><a href="https://blogger.googleusercontent.com/img/a/AVvXsEgwZMmFEmTv2wXOv5V4Jof-Hd2ZOWnzygyYceXMtYdthlWYPU3KyEVsyRN79sHI9bTvnlMKBz_NpkXZ7uZCEVIDAG7xrVvCfP5YMsZPu_tTxv82CX_PUIge9xZvd31V8m89Lex1pD_91WDMH8-8Ba56Q1K5vqFABp2GsKY2QXm0EYjwv-3cUm6chOw=s4608" imageanchor="1" style="margin-left: 1em; margin-right: 1em;"><img border="0" data-original-height="3456" data-original-width="4608" height="240" src="https://blogger.googleusercontent.com/img/a/AVvXsEgwZMmFEmTv2wXOv5V4Jof-Hd2ZOWnzygyYceXMtYdthlWYPU3KyEVsyRN79sHI9bTvnlMKBz_NpkXZ7uZCEVIDAG7xrVvCfP5YMsZPu_tTxv82CX_PUIge9xZvd31V8m89Lex1pD_91WDMH8-8Ba56Q1K5vqFABp2GsKY2QXm0EYjwv-3cUm6chOw=s320" width="320" /></a></div>But just look at it.

On these guide rods would slide an Upper and Lower Guide with set screws to lock them in place. The adjustable Upper Guide would hold the axle for the middle set of gears. The adjustable Lower Guide would hold the KW generator. The first step, green gears (8 T pinion and 64 T ) would be a 1:8 ratio and always stay this way. The yellow 16 tooth gear would always be stacked on the middle axle shaft but the white top gear would be changed out to get any different gear ration between 1:8 and 1:32. The idea here being that perhaps there would be some value in being able to more finely adjust the gear ratio between the blades and the KW generator and get more electrical output?</div><div class="separator" style="clear: both; text-align: center;"><br /></div><div class="separator" style="clear: both; text-align: center;"><a href="https://blogger.googleusercontent.com/img/a/AVvXsEgj5Vz_hTNQ4TERzKc0JIezzVAcas8Ibm9GXur8uFZpfumybpWtNkyx9XTDAVhsFnNiJYBaELE7tFUp7c0u6xpZ1rrGm3JgKlHf1eigV8fCfZfO1tcg9E4wfdWvkadKbnYRTt3ZGCdRjokv6_ONNG2l2w57INY7Un-mhRpH4V2-QicOabomVC_zQNM=s4608" imageanchor="1" style="margin-left: 1em; margin-right: 1em;"><img border="0" data-original-height="3456" data-original-width="4608" height="240" src="https://blogger.googleusercontent.com/img/a/AVvXsEgj5Vz_hTNQ4TERzKc0JIezzVAcas8Ibm9GXur8uFZpfumybpWtNkyx9XTDAVhsFnNiJYBaELE7tFUp7c0u6xpZ1rrGm3JgKlHf1eigV8fCfZfO1tcg9E4wfdWvkadKbnYRTt3ZGCdRjokv6_ONNG2l2w57INY7Un-mhRpH4V2-QicOabomVC_zQNM=s320" width="320" /></a></div><div class="separator" style="clear: both; text-align: center;">So I went to work with my 3D printer and proceeded to make gears with 56, 48 and 40 teeth to fill in some of the ratio gap between the now possible 1:16 and 1:32 ratios using the green KW 64 and 32 tooth gears. </div><div class="separator" style="clear: both; text-align: center;">Note: I also printed off gears with 28, 24, and 20 teeth to fill in the gaps between the now possible 1:8 and 1:16 ratio)</div><div class="separator" style="clear: both; text-align: center;"><br /></div><div class="separator" style="clear: both; text-align: center;"><a href="https://blogger.googleusercontent.com/img/a/AVvXsEjKVEkGIfBJ7Viyzixd1vYYdavCOLC7Fl5Bf5bseVdRmA1PwnYLlUK2f-Dt-7jBfwQ0M3MMcGV4nZ_If-GH-T2kTRK3CVFyTGIGJgAZjhwfBfsd00DMVNNhbSbgC0yzcFrwuhJTWBXN-GUWrF4DwVtopRpe3BsRWpfMDDEDwQw5RmEjsUrOdnaxdao=s4608" imageanchor="1" style="margin-left: 1em; margin-right: 1em;"><img border="0" data-original-height="3456" data-original-width="4608" height="240" src="https://blogger.googleusercontent.com/img/a/AVvXsEjKVEkGIfBJ7Viyzixd1vYYdavCOLC7Fl5Bf5bseVdRmA1PwnYLlUK2f-Dt-7jBfwQ0M3MMcGV4nZ_If-GH-T2kTRK3CVFyTGIGJgAZjhwfBfsd00DMVNNhbSbgC0yzcFrwuhJTWBXN-GUWrF4DwVtopRpe3BsRWpfMDDEDwQw5RmEjsUrOdnaxdao=s320" width="320" /></a></div>So hear is a picture showing the set up for a 1:32 ratio ( 8:64 x 16:64 reduced to 1:8 x 1:4 then to 8 x 4 = 32 for the final two step ratio 1:32) which is now possible.

That this unit is about 4' by 4' and made of several parts requiring assembly. For boiling off 400 gallons of sap to make 10 gallons of syrup (requiring 100 gallons of propane) this set up fit the bill. Then you have to consider tapping 25 trees, placing 50 sap bags and collecting 400 gallons of sap over a week or two and it becomes a job. Not worth the time and effort to just make a gallon or two. Where my idea now is just to have some fun and make a little syrup and be done. </div><div class="separator" style="clear: both; text-align: center;"><br /></div><div class="separator" style="clear: both; text-align: center;"><a href="https://blogger.googleusercontent.com/img/a/AVvXsEi18ojbRvv6ETj1saiiQ8sq4Oueevli7kLsCIOOhP1PnF40PMP9UhzIQR842b5eCeI2Ww3KxiJo-JqasVOiECGAFrpSOPjldvkXl7FXY-_r1BWeOaNp4rv6q6dcIrT691ULOQ6AimhUDyQAhYNNbIyZndfyJ74ah7nN47LNo32IrXaYn3R5YCBY3xc=s4608" imageanchor="1" style="margin-left: 1em; margin-right: 1em;"><img border="0" data-original-height="3456" data-original-width="4608" height="240" src="https://blogger.googleusercontent.com/img/a/AVvXsEi18ojbRvv6ETj1saiiQ8sq4Oueevli7kLsCIOOhP1PnF40PMP9UhzIQR842b5eCeI2Ww3KxiJo-JqasVOiECGAFrpSOPjldvkXl7FXY-_r1BWeOaNp4rv6q6dcIrT691ULOQ6AimhUDyQAhYNNbIyZndfyJ74ah7nN47LNo32IrXaYn3R5YCBY3xc=s320" width="320" /></a></div><div class="separator" style="clear: both; text-align: center;">Enter the MMSC (Micro Maple Syrup Cooker) A friend and fellow maple syrup maker got some equipment from me a few years ago to give making syrup a try. When I saw his set up using a turkey cooker I got this idea. Menards had a sale on turkey cookers so I bought one for $100. Here you can see the turkey cooker set up on it's stand. To the right is the sap feeding system connected by a pipe to the cook pot. The sap feeding system is a metal box with a stock tank float in it. The green hose connected to the stock tank float goes up to the sap supply resevoir. The float is set so that the level of sap in the cooking pot will be about two inches deep. Keep in mind that a deep liquid requires a lot of heat an time to boil. The best boiling takes place when the liquid level is about 2 inches deep. To do this manually you would have to stay by the cooker and add a gallon of sap every 15 minutes. My friend can tell you what happens if you let the level get to low and the pan burn. Yeks! With my system as the level of sap boils off and goes down in the cook pot the float sinks, opening the valve allowing sap to flow from the reservoir keeping the level of sap in the cooker at 2" at all times. With a 30 gallon reservoir supply of sap you are good to go for several hours. Just light 'er up and let it boil. But don't let the reservoir run dry!</div><div class="separator" style="clear: both; text-align: center;"><br /></div><div class="separator" style="clear: both; text-align: center;"><a href="https://blogger.googleusercontent.com/img/a/AVvXsEiafd1miLwIAvcdzUJZP0Z_tlZPmQfZtTwFZWQbY_jKqLURZ-4nFq61aNvDHWAaYZwDmr_RhY275Z1MyQlhshfu4zu-IZquiYXqF7noTt0_bVVaiv7dnbPeS50k-bHgsDAITkebwscEZtNe6PKImD9U-fMearp_-AQ1y5qT-uMnRxXB_5mkr6tupsU=s4608" imageanchor="1" style="margin-left: 1em; margin-right: 1em;"><img border="0" data-original-height="3456" data-original-width="4608" height="240" src="https://blogger.googleusercontent.com/img/a/AVvXsEiafd1miLwIAvcdzUJZP0Z_tlZPmQfZtTwFZWQbY_jKqLURZ-4nFq61aNvDHWAaYZwDmr_RhY275Z1MyQlhshfu4zu-IZquiYXqF7noTt0_bVVaiv7dnbPeS50k-bHgsDAITkebwscEZtNe6PKImD9U-fMearp_-AQ1y5qT-uMnRxXB_5mkr6tupsU=s320" width="320" /></a></div><div class="separator" style="clear: both; text-align: left;">Here is a picture of the sap feeding system.

The valve will stop valuable finished maple syrup (it take 40 gallons of sap to make 1 gallon of syrup) from coming out when the union is disconnected so the pot, with the finished maple syrup in it can be lifted up and dumped out for filtering and canning. Right now the system is sitting on a temporary base set up. A better more secure platform with a base will be made in the near future.</div><div class="separator" style="clear: both; text-align: left;"><br /></div><div class="separator" style="clear: both; text-align: left;"><div class="separator" style="clear: both; text-align: center;"><a href="https://blogger.googleusercontent.com/img/a/AVvXsEgnnOHnfRaa8DFY2mkmFNC9Pjh3g_101eRX1UcwL2Sa1Qv4XbMS9NWQjiZ2yozmlqrpYzhhkRMreAoNkZjQSl_sS8pfIQiDujuOHMclIdm6E5t78qArhwQZob2XIfF3DFj_PmOGPcgIWgC-V9JpbNtxEV2bYcr7MAIRxydAC6YNEp5sHSUbmoxXeLY=s4608" imageanchor="1" style="margin-left: 1em; margin-right: 1em;"><img border="0" data-original-height="3456" data-original-width="4608" height="240" src="https://blogger.googleusercontent.com/img/a/AVvXsEgnnOHnfRaa8DFY2mkmFNC9Pjh3g_101eRX1UcwL2Sa1Qv4XbMS9NWQjiZ2yozmlqrpYzhhkRMreAoNkZjQSl_sS8pfIQiDujuOHMclIdm6E5t78qArhwQZob2XIfF3DFj_PmOGPcgIWgC-V9JpbNtxEV2bYcr7MAIRxydAC6YNEp5sHSUbmoxXeLY=s320" width="320" /></a></div>A look below the cooking pot shows the heat that is produced.

My goal here is to change that for KidWind students to mean Lock Out Tag Out. A system of safety measures (locks and tags) that wind turbine technicians use when working on turbines to prevent anyone from turning on the power while work (mechanical, electrical, hydraulic etc.) is being done. To that end I have constructed a working model of a 2MW Vestas turbine. While the model does not produce electricity it has all the major parts and each of them can be locked out to duplicate LOTO procedures that a service technician needs to preform using the actual locks and tags of the trade.</div><div class="separator" style="clear: both; text-align: center;"><br /></div><div class="separator" style="clear: both; text-align: center;"><br /></div><div class="separator" style="clear: both; text-align: center;"><a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEj-GKidQzmKMcCA3NcbhOMbITo9eGecCNVm_D0PmCxMw3_oXnh6KPfgfvVB5zaH_NKXVLvivG2V-KAyODbLeqLR1nxR0fKWw0QjOE3dfMRlQ9gobR4qvkd00mgwG3yvPQUmqQoBzxsXsDg/s2048/IMG_3883.jpg" imageanchor="1" style="margin-left: 1em; margin-right: 1em;"><img border="0" data-original-height="1536" data-original-width="2048" height="240" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEj-GKidQzmKMcCA3NcbhOMbITo9eGecCNVm_D0PmCxMw3_oXnh6KPfgfvVB5zaH_NKXVLvivG2V-KAyODbLeqLR1nxR0fKWw0QjOE3dfMRlQ9gobR4qvkd00mgwG3yvPQUmqQoBzxsXsDg/s320/IMG_3883.jpg" width="320" /></a></div>Left to right we start out with the Rotor. This holds the three blades and the mechanisms that pitch the blades which in turn control the speed of rotations for different wind velocities. Next is the main drive shaft that connects the Rotor to the Gearbox where the low rpms of the Rotor (16 rpm) are sped up to over 1,200 rpm to turn the shaft of the electric generator ( black component at the end ) to produce 2MW's of electricity. <br /><div class="separator" style="clear: both; text-align: center;"><br /></div><div class="separator" style="clear: both; text-align: center;"><a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEiHf67DLqowBUi2cF55vZHKLopFkAF1hKFD7eaW_N8EhjFY8-Cm29SiCLFDKwFnLbd_1uH4xvhxgLZ48Ddyx2FvgzwCetvHmSGJBFo_9fzEZfDfuqYQ4eCeXRDPj7Z79JWVBOjzF59FfG4/s2048/IMG_3887.jpg" imageanchor="1" style="margin-left: 1em; margin-right: 1em;"><img border="0" data-original-height="1536" data-original-width="2048" height="240" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEiHf67DLqowBUi2cF55vZHKLopFkAF1hKFD7eaW_N8EhjFY8-Cm29SiCLFDKwFnLbd_1uH4xvhxgLZ48Ddyx2FvgzwCetvHmSGJBFo_9fzEZfDfuqYQ4eCeXRDPj7Z79JWVBOjzF59FfG4/s320/IMG_3887.jpg" width="320" /></a></div><div class="separator" style="clear: both; text-align: left;">Between the Gearbox and the Generator is a Disc Brake that is used as a fail-safe. Also in this close up you can see the four Yaw motors that control the rotation of the Nacelle on the top of the tower to keep the Rotor blades pointed into the wind at all times.</div><div class="separator" style="clear: both; text-align: left;"><br /></div><div class="separator" style="clear: both; text-align: center;"><a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEiqGFwsFlBqulqIVJt3UlaL4XNhyLMb2cI51DlI9Z0u9wg6oeB0r2p0PnGelL8r-EakWfeHnXGKo_Nva1I7RhZtNmMdn0XNTKtOREDqdWGis1SHhW86joXSmMkTJaxWWHlM6KeSdi0MQbU/s2048/IMG_3888.jpg" imageanchor="1" style="margin-left: 1em; margin-right: 1em;"><img border="0" data-original-height="1536" data-original-width="2048" height="240" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEiqGFwsFlBqulqIVJt3UlaL4XNhyLMb2cI51DlI9Z0u9wg6oeB0r2p0PnGelL8r-EakWfeHnXGKo_Nva1I7RhZtNmMdn0XNTKtOREDqdWGis1SHhW86joXSmMkTJaxWWHlM6KeSdi0MQbU/s320/IMG_3888.jpg" width="320" /></a></div>Here you can see two pins in the Nacelle have been pushed down so they go through two eye bolts, on the tower. One has been secured with a nut and the other has been tagged and locked out with a special padlock. The technician performing the work will fill out the tag with all of the necessary information. The padlock has only one key and it will remain with the operator. This way only the operator can remove the lock and allow the Nacelle to Yaw when the work has been done.<p></p><p><br /></p><p></p><div class="separator" style="clear: both; text-align: center;"><a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEgVZxy__dVmCWxtKgzNaPrnCvlXVqZKZbvhaZ-4af9XJCEkf0ja7kYyvuWxs4kWdxUuWorhJ1uPrSHTK0kYc9TpmuizGddH72mfQb4n1Ei-yNoe_MmZH5wHOZ-6JhTZtrAtzlfcOzfXSSU/s2048/IMG_3884.jpg" imageanchor="1" style="margin-left: 1em; margin-right: 1em;"><img border="0" data-original-height="1536" data-original-width="2048" height="240" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEgVZxy__dVmCWxtKgzNaPrnCvlXVqZKZbvhaZ-4af9XJCEkf0ja7kYyvuWxs4kWdxUuWorhJ1uPrSHTK0kYc9TpmuizGddH72mfQb4n1Ei-yNoe_MmZH5wHOZ-6JhTZtrAtzlfcOzfXSSU/s320/IMG_3884.jpg" width="320" /></a></div> Another point that may need to be controlled is the rotation of the Rotor. This is done from the back side of the Rotor inside of the Nacelle.<p></p><p><br /></p><div class="separator" style="clear: both; text-align: center;"><a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEg6HkkZW740QRJnEDVg4OZPN88MwIkrlZTm5yOxSuhUwj9iTJ0APqWD535PixeQ85f04bTgIXGxTy0ElIIuZ6cks684hJXQUxdr-zkPvjXs9klfaKlFtias1oSZHbOdPPG7iwrb29hT8YM/s2048/IMG_3892.jpg" imageanchor="1" style="margin-left: 1em; margin-right: 1em;"><img border="0" data-original-height="1536" data-original-width="2048" height="240" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEg6HkkZW740QRJnEDVg4OZPN88MwIkrlZTm5yOxSuhUwj9iTJ0APqWD535PixeQ85f04bTgIXGxTy0ElIIuZ6cks684hJXQUxdr-zkPvjXs9klfaKlFtias1oSZHbOdPPG7iwrb29hT8YM/s320/IMG_3892.jpg" width="320" /></a></div>So now we have gone around to the back side of the Rotor. Here you can see two pins. Like for the Yaw these two pins are pushed into holes in the Rotor to keep it from rotating. Notice the numbers. Each of the three blades can be locked out so that they are in the horizontal position. Believe it or not the blades are hollow and technicians need to get inside for inspections. Also to get into the nose of the Rotor they have to squeeze through the small semi-circle openings shown. Again a tag and lock can be placed safely locking the Rotor when necessary.<div><br /></div><div><br /></div><div class="separator" style="clear: both; text-align: center;"><a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEg2RlaZVcK28o2RjkpN9fhf475UKfdrFf6jLiJmCwdTeWhjrZ-nGxheb5WIekOi7Pvuc-OwL53rIXb844gq9an-ghqYo0NyvChJNYtPokQm-B2CluwdPW5sHbRrmBicmYvSx52Fdn6LczA/s2048/IMG_3885.jpg" imageanchor="1" style="margin-left: 1em; margin-right: 1em;"><img border="0" data-original-height="1536" data-original-width="2048" height="240" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEg2RlaZVcK28o2RjkpN9fhf475UKfdrFf6jLiJmCwdTeWhjrZ-nGxheb5WIekOi7Pvuc-OwL53rIXb844gq9an-ghqYo0NyvChJNYtPokQm-B2CluwdPW5sHbRrmBicmYvSx52Fdn6LczA/s320/IMG_3885.jpg" width="320" /></a></div>Here we are back out front looking into the Rotor where the three blades are attached. Each blade has to be able to change pitch as the velocity of the wind changes. This is done with double acting hydraulic cylinders through linkage to the blade mounting plate. The bearings for the blades have an inner and outer race with bearings between them to handle the extremely high load forces. You can see the ball bearings for blade #2 in the picture. To lock the blades the hydraulics are shut off and two pins are screwed in from the outer race to eye screws mounted in the inner race plates. Notice the hole in the inner race. This is where the technician would crawl through to get inside the blade for inspections.<div><br /></div><div class="separator" style="clear: both; text-align: center;"><a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEjRIKsrD4IaAaRHibAthD_p2KTDaqrWe_e8lSMbzyjH6k_i_ph1t46E-x19N4Csy6IgzhUPupYMfTh3d1RhIPVX0iGfweKxXaed2sd7VoYs-XypYVewxDNldchEwd3nmcieikKqQ8t_7RU/s2048/IMG_3893.jpg" imageanchor="1" style="margin-left: 1em; margin-right: 1em;"><img border="0" data-original-height="1536" data-original-width="2048" height="240" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEjRIKsrD4IaAaRHibAthD_p2KTDaqrWe_e8lSMbzyjH6k_i_ph1t46E-x19N4Csy6IgzhUPupYMfTh3d1RhIPVX0iGfweKxXaed2sd7VoYs-XypYVewxDNldchEwd3nmcieikKqQ8t_7RU/s320/IMG_3893.jpg" width="320" /></a></div>Tagging and locking these two screws in this model requires the use of a special String Lock Out. The flexible nylon string is threaded through the two nuts welded at the end of each locking screw and then back through the handle where it is clamped and locked with a padlock. This way the screws cannot be turned until the work is done and technician safe.<div><br /></div><div class="separator" style="clear: both; text-align: center;"><a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEhPXQjC5NwQdj02blcW3AD8FZanc1b5-5Wtsgz3Ypa-2n22Q77adL34pCCxzhOue6o2MkvkXfvpKWZqkaNxgY_rWGJ8aiTZAe2fgS3zfr5xT2nLuFHsdwtm1iaLrTB-pzudgcCAh42iDHI/s2048/IMG_3887+2.jpg" imageanchor="1" style="margin-left: 1em; margin-right: 1em;"><img border="0" data-original-height="1536" data-original-width="2048" height="240" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEhPXQjC5NwQdj02blcW3AD8FZanc1b5-5Wtsgz3Ypa-2n22Q77adL34pCCxzhOue6o2MkvkXfvpKWZqkaNxgY_rWGJ8aiTZAe2fgS3zfr5xT2nLuFHsdwtm1iaLrTB-pzudgcCAh42iDHI/s320/IMG_3887+2.jpg" width="320" /></a></div>Finally we come to the Disc-brake. Rich, from Oneota Cycles in Decorah, IA had just what I need for this in his scrap bin. The disc brake provides some control of the Rotor between the time the turbine is shut off and the two pins are place into the rotor for a more positive and secure lock to prevent the Rotor from spinning.<div><br /></div><div class="separator" style="clear: both; text-align: center;"><a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEi4L5hb6FvevtMTOmxq4Mhaj-oQGp9bxngXx_EdZMCXp9hETXOVhPqYF04AAduDy3T20YxWAMdYbH53pTesIzZXXFHPA6kUHqylYQgSG58YocPAk11OYu9dRBUB8F1ylcLJOQ9srpZPDy0/s2048/IMG_3895.jpg" imageanchor="1" style="margin-left: 1em; margin-right: 1em;"><img border="0" data-original-height="1536" data-original-width="2048" height="240" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEi4L5hb6FvevtMTOmxq4Mhaj-oQGp9bxngXx_EdZMCXp9hETXOVhPqYF04AAduDy3T20YxWAMdYbH53pTesIzZXXFHPA6kUHqylYQgSG58YocPAk11OYu9dRBUB8F1ylcLJOQ9srpZPDy0/s320/IMG_3895.jpg" width="320" /></a></div>So how is this hands on LOTO training model going to be used with students? There will be a series of toggle switches like this in a control panel. Each will be labeled for the different turbine components with LED's. The Red LED's when lit will indicate a live circuit condition and a Green LED indicating safe to work on. Think of it like a fuse box in your home. You turn the circuit breaker off for the circuit that you are going to be working on. In this case the Green LED would light up showing that you have de-energized that part of the wind turbine. After you tag and lock it out it will be safe to work on.<div><br /></div><div>So ask yourself if you were the technician and your job was to repair the following turbine problems what would you tag out?

So what goes into designing and planning a tilt up tower for a 300 watt Air-X wind turbine? <p></p><p>I hear or read, I forget. I see or watch, I remember. I do it, I understand!</p><p>This will be about a guyed "tilt-up" tower. The big question. How strong is strong enough? Design and build your system to stand up to 50 m/s (110 mph) max force wind (worst case) with a safety factor of five and you will be able to sleep through any weather event!</p><p>Lets look at the F.A.T. (Frontal Area of the Tower) and swept area of the turbine. At 50 m/s you can count on a force of 250 kg/square meter of area to the wind.</p><p>We have a .1m wide by 6m tower = .6 sq/m and a .6m radius rotor on the Air-X = 1.13 sq/m </p><p>Total FAT = 1.73 sq/m x 250 kg = 432.5 kg (951.5 lbs) force at 50 m/s (110 mph) wind velocity. Times the safety factor of 5 means designing it to withstand 2162 kg (4757 lbs) of force. </p><p>This will help decide the rigging and anchor sizes needed for the tower guys.</p><p>Now the raising of the tower is another story...</p><p>In our example with a 6m (19.5 ft.) tower weighing 17.27 kg (38 lbs) and 11.36 kg (25 lb) 300 watt turbine for a total weight of 28.63 kg (63 lbs) you could probably just "muscle" the tower up to vertical and tighten up the guys. However this will help prepare you for bigger projects.</p><p>Anyway you need to think about the forces at play when you try to lift a hinged tower, to vertical, with a weight at the end of tower by pulling on a rope. </p><p>First, understand that lifting a 28.63 kg (63 lb) weight straight up with a rope would require a force of 28.63 kg (63 lbs)</p><p>Second, understand that lifting a weight by pulling at an angle is going to require more force than the weight of the object (the pole and turbine) you are lifting.</p><p>Third, the angles of the lifting rope to the weight determine the fore you will need to lift the tower and turbine.</p><div class="separator" style="clear: both; text-align: center;"><a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEjkE3BhiHxg7t4FKz5WYY1rk-1rHpgdG43DdVNjzyjU2QWAAigGrNV6fsVETZ870zok-DbqZNwsKj8Z8JeXW7OG8CQbfcbLLV6npK1hKX95G7AZaRUPMR3zV_AC02gXZsjDv20gz9RwUkk/s2048/IMG_3838.jpg" imageanchor="1" style="margin-left: 1em; margin-right: 1em;"><img border="0" data-original-height="1536" data-original-width="2048" height="240" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEjkE3BhiHxg7t4FKz5WYY1rk-1rHpgdG43DdVNjzyjU2QWAAigGrNV6fsVETZ870zok-DbqZNwsKj8Z8JeXW7OG8CQbfcbLLV6npK1hKX95G7AZaRUPMR3zV_AC02gXZsjDv20gz9RwUkk/s320/IMG_3838.jpg" width="320" /></a></div>The vertical line in the drawing represents the gin pole.

In this case the thimble is being attached to a turnbuckle. Notice how the thimble has been twisted so it will allow the closed end of the turnbuckle in.

For a guyed tower the base needs minimal support as compared to a free standing tower. So here the two rods will be driven into the ground to hold the base in place while the tower is being raised. A punch is being used to start the holes for the two rods.

It is anchored in place with four 12" long 2" diameter screw in anchors. 1/2" diameter steel rods are slid through the eyes of each anchor and over the top of the mounting board the winch is on. As a recommended safety precaution the hand crank will be used for the first test raising so the resistance in the (anchor and lifting) cable lines to the lift can be felt and adjusted if needed. A power drill can be used after the system is proved out and safe. </div><div><br /></div><div class="separator" style="clear: both; text-align: center;"><a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEh4nK2-P-DcESdtPIgIqDfR42oX4MStW7g7bETfMSzf9R_aAtYRkGjzHUr9XQOhlef3cd6AJaq9yCITpA6JTiWF2F5sKEeT9YhE3lTbAzYRbWAbsZy8PRcSH4uceMZi58fTqipkM7yN8-E/s2048/IMG_3802.jpg" imageanchor="1" style="margin-left: 1em; margin-right: 1em;"><img border="0" data-original-height="1536" data-original-width="2048" height="240" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEh4nK2-P-DcESdtPIgIqDfR42oX4MStW7g7bETfMSzf9R_aAtYRkGjzHUr9XQOhlef3cd6AJaq9yCITpA6JTiWF2F5sKEeT9YhE3lTbAzYRbWAbsZy8PRcSH4uceMZi58fTqipkM7yN8-E/s320/IMG_3802.jpg" width="320" /></a></div>This shows the hinge line for the tower. The location of the anchor points have been chosen and calculated. I say chosen because several factors come into play here. The idea distance would be so that the anchor cables were at 45 degree angles to the tower but that takes up a lot of area. So by doing some Force and Tension In A Rope Due To Angle calculations found on the <span style="color: red;">www.EngineeringToolBox.com</span> web site I came up with this distance. Also for my application these anchor points are also used as lifting anchors to stabilize the gin pole. Lets me get by with two anchors instead of four along this hinge line.<div><br /></div><div class="separator" style="clear: both; text-align: center;"><a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEjDp0Y9mNTOtYvhGQQXHIJenVu0YKST3Se89I7ge_wbuYGH3nReBk2d2v-_1ugeYu5fHEhrBcHUlUGJIxuZcy0W3a6zvnBF8BIh0dTo7dMzlI5QofiPg47bSqtkpTfzj1BfDJq1HqLpb2c/s2048/IMG_3805.jpg" imageanchor="1" style="margin-left: 1em; margin-right: 1em;"><img border="0" data-original-height="1536" data-original-width="2048" height="240" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEjDp0Y9mNTOtYvhGQQXHIJenVu0YKST3Se89I7ge_wbuYGH3nReBk2d2v-_1ugeYu5fHEhrBcHUlUGJIxuZcy0W3a6zvnBF8BIh0dTo7dMzlI5QofiPg47bSqtkpTfzj1BfDJq1HqLpb2c/s320/IMG_3805.jpg" width="320" /></a></div>Here we are all rigged and ready for the test lift. This is done without the generator being mounted so that if anything should be wrong or goes wrong you don't have all the weight to deal with. Also dropping the generator would most certainly wreck the blades and damage the Nacelle at the very least. A well designed and rigged system should be easy to raise and lower. This will need to be done for annual maintenance anyway.<div><br /></div><div><div class="separator" style="clear: both; text-align: center;"><a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEiF7ctsOa0sXUuncQmeNGjhh9SifS6LxVpGTuopw8wXYN50iUyOY9hMO2K_CM3XywjW2smN_kEqg_aTyld3P1UZPnFHlTtBl5DOC9egZmRC3zq8i4dDmeneH1-t8ajRNuJgIRpf2Iwk_OM/s2048/IMG_3808.jpg" imageanchor="1" style="margin-left: 1em; margin-right: 1em;"><img border="0" data-original-height="1536" data-original-width="2048" height="240" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEiF7ctsOa0sXUuncQmeNGjhh9SifS6LxVpGTuopw8wXYN50iUyOY9hMO2K_CM3XywjW2smN_kEqg_aTyld3P1UZPnFHlTtBl5DOC9egZmRC3zq8i4dDmeneH1-t8ajRNuJgIRpf2Iwk_OM/s320/IMG_3808.jpg" width="320" /></a></div>Going up nicely. This project is way over engineered I am using a scrap 6 m aluminum light pole for the tower. Plenty of strength of the weight of my 15 pound 300 w Air-X generator.

As the cabin is built on a concrete slab this should make a big difference in the winter comfort level and enjoyment of the cabin.</p><div class="separator" style="clear: both; text-align: center;"><a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEieXEfpyCTFEkZ9NzCFcTUnqOEgteqyHFFrA294GLXKenpnyg3KwUBIT4CxksLx1t_gbV3GImq6YRWj3gHUjNn5HKlnqKwTh63Y2vmziOxgaQsuOh6qGYz-NiFffAXrxkER0Ej9aCv0l4E/s2048/IMG_3769.jpg" imageanchor="1" style="margin-left: 1em; margin-right: 1em;"><img border="0" data-original-height="1536" data-original-width="2048" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEieXEfpyCTFEkZ9NzCFcTUnqOEgteqyHFFrA294GLXKenpnyg3KwUBIT4CxksLx1t_gbV3GImq6YRWj3gHUjNn5HKlnqKwTh63Y2vmziOxgaQsuOh6qGYz-NiFffAXrxkER0Ej9aCv0l4E/s320/IMG_3769.jpg" width="320" /></a></div>I decided to lay down 3/4" of foil faced insulation on the concrete floor as a thermal break to the cold.<div><br /></div><div class="separator" style="clear: both; text-align: center;"><a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEg-e_CmZ5J2Ci1KkP4aPyPbNIT92_pOcOo1ULh80Ce55r2rn9-fXj8CPNip5OV_EkVZNCu7UyzJO-kmkwaKbbnMjBrz6uGuNhn6AqumbAfDPVovcmpNyj8OuMFAEsMsZI70F8pS_s-yrP8/s2048/IMG_3770.jpg" imageanchor="1" style="margin-left: 1em; margin-right: 1em;"><img border="0" data-original-height="1536" data-original-width="2048" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEg-e_CmZ5J2Ci1KkP4aPyPbNIT92_pOcOo1ULh80Ce55r2rn9-fXj8CPNip5OV_EkVZNCu7UyzJO-kmkwaKbbnMjBrz6uGuNhn6AqumbAfDPVovcmpNyj8OuMFAEsMsZI70F8pS_s-yrP8/s320/IMG_3770.jpg" width="320" /></a></div>Next the system I choose comes with a mate that is laid down and the heating resistance wire is snapped into. I comes in 3 foot wide rolls and cuts easily with a utility knife.<div><br /></div><div class="separator" style="clear: both; text-align: center;"><a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEiZ4LP9Vjl60oRxCZQ-6p9emGMe9kwiGkbDrhUXy6WWnPvZ0JVDxzH7K2f0GxCyzN8dTggfqvV04OytNwlgvLevqi04wOs5zSQIe-1ey5mBfIjkPk1OzFgoBOBimzhEgoMube1ZdYmKdRo/s2048/IMG_3771.jpg" imageanchor="1" style="margin-left: 1em; margin-right: 1em;"><img border="0" data-original-height="1536" data-original-width="2048" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEiZ4LP9Vjl60oRxCZQ-6p9emGMe9kwiGkbDrhUXy6WWnPvZ0JVDxzH7K2f0GxCyzN8dTggfqvV04OytNwlgvLevqi04wOs5zSQIe-1ey5mBfIjkPk1OzFgoBOBimzhEgoMube1ZdYmKdRo/s320/IMG_3771.jpg" width="320" /></a></div>OK now with the mate down it was time to start snapping in the heating wire. For this system the wire is spaced every three cones. There are some rules for this and every system is different. For this one no wires can cross and the length cannot be cut. So you have to order the exact length for the area you are heating. My supplier did all this and it worked out just fine. The sensor wire for the system cannot cross over any wires and should be located near the center of the room. In most situations this type of floor is used where ceramic tile is used for the finish floor. I wanted to use laminate plank. <div><br /></div><div class="separator" style="clear: both; text-align: center;"><a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEiEjYBr3Upz3HYMDZRe-GRvsCbKXpjb4BRsYRCA1XmRx9IQ8A1vBU6Td0TqfQnZP2koZ34xuetsZXt18I8E8N1OyGjrDbgGB7d6_a1nueAj-j5IJUhCa9mSdLPao5aFC3yXwf9qwkJnJmI/s2048/IMG_3772.jpg" imageanchor="1" style="margin-left: 1em; margin-right: 1em;"><img border="0" data-original-height="1536" data-original-width="2048" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEiEjYBr3Upz3HYMDZRe-GRvsCbKXpjb4BRsYRCA1XmRx9IQ8A1vBU6Td0TqfQnZP2koZ34xuetsZXt18I8E8N1OyGjrDbgGB7d6_a1nueAj-j5IJUhCa9mSdLPao5aFC3yXwf9qwkJnJmI/s320/IMG_3772.jpg" width="320" /></a></div><br /><div>Nice. Finished laying the heating wire. Now to place the two sensors and their wires. They send two sensors so there is a back up should one fail. For me it would be a big pain to pull up the finish floor. For a ceramic floor it would be impossible. So two is better than one. However the wiring for all this is another learning experience. A lot of online video to help and the second time will be easier.</div><div><br /></div><div class="separator" style="clear: both; text-align: center;"><a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEgocMMg3VKwKZjzHEKvOnO4ia8kOvr9K_9nkQybSJvuXkphvHi36jaGxbxgJ3NDFvN4SfNZZg4wPHIwbzwVRI9C8pqU0SkmIh-7PwVt6DwmcHpN_bOHhp8qV36WIisGiBqr6wCmbmyEcCE/s2048/IMG_3774.jpg" imageanchor="1" style="margin-left: 1em; margin-right: 1em;"><img border="0" data-original-height="1536" data-original-width="2048" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEgocMMg3VKwKZjzHEKvOnO4ia8kOvr9K_9nkQybSJvuXkphvHi36jaGxbxgJ3NDFvN4SfNZZg4wPHIwbzwVRI9C8pqU0SkmIh-7PwVt6DwmcHpN_bOHhp8qV36WIisGiBqr6wCmbmyEcCE/s320/IMG_3774.jpg" width="320" /></a></div>The final step would be the finish flooring. I used snap together vinyl laminate. This required a thin layer of foam to be laid down over everything. Snap it together leaving a 3/8" gap for expansion and you have a nice durable cabin floor in a couple of hours.<div><br /></div><div class="separator" style="clear: both; text-align: center;"><a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEjVdN52BvBe1QyAxqWU7SLzjNnR8gzVKAsuX7cggwe1Z-uvBCxNmSnE7r4y6r9Cx-Bk4RE61haNokvlFvv_MGn2-0fVuqGCsKMo_FTJrZgEM34woXAaxvjZnbgOC6Buk5a6CbYAEJmspjk/s2048/IMG_3775.jpg" imageanchor="1" style="margin-left: 1em; margin-right: 1em;"><img border="0" data-original-height="1536" data-original-width="2048" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEjVdN52BvBe1QyAxqWU7SLzjNnR8gzVKAsuX7cggwe1Z-uvBCxNmSnE7r4y6r9Cx-Bk4RE61haNokvlFvv_MGn2-0fVuqGCsKMo_FTJrZgEM34woXAaxvjZnbgOC6Buk5a6CbYAEJmspjk/s320/IMG_3775.jpg" width="320" /></a></div>And there you have it. You can see the main power service panel. The cold end of the heating wire had to be routed up to the thermostat along with the 220 volt supply power and two temperature sensor wires. This all terminate out of view in this picture at the top of PVC pipe where the control thermostat is located. This company is pretty strict about testing the heating wire and sensor wires for resistance and shorts before, during and after installation. But all is well. Will wait until fall to make the finals connections and put the floor to work.<div><br /></div><div>Well I hope you have enjoyed the journey and process of designing and building my Hand Hewn Log Cabin #6 as much as I have over the past year or two.<br /><div><br /><div><br /><div><br /><div><br /><p><br /></p></div></div></div></div></div>Dickhttp://www.blogger.com/profile/13870935149581761539noreply@blogger.com0tag:blogger.com,1999:blog-5754440625977916703.post-4196861401286466442021-06-23T19:56:00.000-07:002021-06-23T19:56:20.017-07:00Treehouse Phase V - The Enjoyment Phase<p> </p><div class="separator" style="clear: both; text-align: center;"><a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEggVKSLE9Bmdk1tej98f24spaJcVoBBHZfT-s7Xwy5hU0MGT7BhtGPIX9brBBHFAeIrq7G0fxBc4_xFeUdhP6inyWs0vhz2uOaE7GJlU9DUBgSLQF8Uh_eUG3f45bVJeaT9Miou3JBvcRI/s2048/IMG_3757.jpg" imageanchor="1" style="margin-left: 1em; margin-right: 1em;"><img border="0" data-original-height="1536" data-original-width="2048" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEggVKSLE9Bmdk1tej98f24spaJcVoBBHZfT-s7Xwy5hU0MGT7BhtGPIX9brBBHFAeIrq7G0fxBc4_xFeUdhP6inyWs0vhz2uOaE7GJlU9DUBgSLQF8Uh_eUG3f45bVJeaT9Miou3JBvcRI/s320/IMG_3757.jpg" width="320" /></a></div>OK so with the reassembly phase complete it was time to put on the rubber membrane roof material. It was a calm day so I took advantage of it.<p></p><p><br /></p><div class="separator" style="clear: both; text-align: center;"><a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEgXkyjZYGmOwe6bMQKLwJEtAE0w1w7aMuCA45ICms5bx_9BaxvZLXZRbCBpcBABLEZi-Z4qlEqm0ZMvEUxeOnN1ToOCfmUT-GpgqO8XF3vElgLXHwQOX8x08C1fOHli8FDGo-VwzWLzYUs/s2048/IMG_3758.jpg" imageanchor="1" style="margin-left: 1em; margin-right: 1em;"><img border="0" data-original-height="1536" data-original-width="2048" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEgXkyjZYGmOwe6bMQKLwJEtAE0w1w7aMuCA45ICms5bx_9BaxvZLXZRbCBpcBABLEZi-Z4qlEqm0ZMvEUxeOnN1ToOCfmUT-GpgqO8XF3vElgLXHwQOX8x08C1fOHli8FDGo-VwzWLzYUs/s320/IMG_3758.jpg" width="320" /></a></div>Now if you have been following this process you remember how the membrane was laid out in place on the roof the first time. The process was a struggle even when there was the possibility of working with this sheet of material from the ground. So when we took it off I carefully folded it like a giant pie crust and marked the starting location with detailed instructions for unfolding. This had to go exactly in place the first time when working only from the hatch opening in the roof. I loaded the 80 pound bundle on the elevator and crossed my fingers. It was a success! The loose edge s would be pulled down and wrapped around the fascia then stapled to the inside. Then a 1x2 strip would be screwed over the staples and screwed down to clamp it in place.<div><br /></div><div class="separator" style="clear: both; text-align: center;"><a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEi-q2FmNkevUlqdDi-30ygQ3981cvW6Y9oGMLLGw4rVZuHMJb5UJMqqLlLd6mcf28ehCMAEJwBVWJP5QAhVJ7EBoiuYH_AtAQw77S6tN6e2SJq7I3ZlLPSPqgOiPIIBfWVufEjKpIFqq-8/s2048/IMG_3759.jpg" imageanchor="1" style="margin-left: 1em; margin-right: 1em;"><img border="0" data-original-height="2048" data-original-width="1536" height="320" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEi-q2FmNkevUlqdDi-30ygQ3981cvW6Y9oGMLLGw4rVZuHMJb5UJMqqLlLd6mcf28ehCMAEJwBVWJP5QAhVJ7EBoiuYH_AtAQw77S6tN6e2SJq7I3ZlLPSPqgOiPIIBfWVufEjKpIFqq-8/s320/IMG_3759.jpg" /></a></div><div>With the roof membrane down and secured it was time to bring up the windows.

I knew from the start this project would be a challenge and a learning process but I tried not to think to much about it and just plunged forward. For every problem there was a solution and this is the proof of that. I have to give a big shout out to my good friend Jerry for without his help and many ideas throughout the process I could not have done this. My advise if you are going to try something cool like this is make sure you have a guy like Jerry around.<br /> <br /><div><br /><div><br /></div><div> <br /><p><br /></p></div></div></div>Dickhttp://www.blogger.com/profile/13870935149581761539noreply@blogger.com0tag:blogger.com,1999:blog-5754440625977916703.post-27384757054787829332021-06-22T03:25:00.003-07:002021-06-22T03:25:49.849-07:00Reassembly of the hexagon and roof frame<p> </p><div class="separator" style="clear: both; text-align: center;"><a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEh9TT3AuSjsSxaHv-3cXGHUZFNg6RBG8pzRUd1Uwpe9L3ICRF8A-UP6U2OjXE3HOGCsKgz2WJO1UPYy9YNRklj5jwzuBHbTlA4rOAGPojq2FAaiiNYNHC6Y-FzqlZGGFmuBsf72nsZ4Elw/s2048/IMG_3741.jpg" imageanchor="1" style="margin-left: 1em; margin-right: 1em;"><img border="0" data-original-height="1536" data-original-width="2048" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEh9TT3AuSjsSxaHv-3cXGHUZFNg6RBG8pzRUd1Uwpe9L3ICRF8A-UP6U2OjXE3HOGCsKgz2WJO1UPYy9YNRklj5jwzuBHbTlA4rOAGPojq2FAaiiNYNHC6Y-FzqlZGGFmuBsf72nsZ4Elw/s320/IMG_3741.jpg" width="320" /></a></div>With the floor done it was now time to begin to reassemble the corner posts that would support the hexagon roof frame. The elevator would come in very handy for this task.

The header is fastened to the posts with 4" wide nail plates and screws. <div><br /></div><div><br /></div><div><div class="separator" style="clear: both; text-align: center;"><a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEhqK5ZfvjVY6mWyJg9goYqCIh5Xe5HcU-qWUii8x9ixPk9UB6X8EnKP2AxumI-GFZ8Q4vW4clr2Hc_Rrk_NYJG1bkUbWNoYQIypnZhpUn4weB7gqFVo7CaBxn7v4VMtWC3anhreVMbs5zM/s2048/IMG_3749.jpg" imageanchor="1" style="margin-left: 1em; margin-right: 1em;"><img border="0" data-original-height="1536" data-original-width="2048" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEhqK5ZfvjVY6mWyJg9goYqCIh5Xe5HcU-qWUii8x9ixPk9UB6X8EnKP2AxumI-GFZ8Q4vW4clr2Hc_Rrk_NYJG1bkUbWNoYQIypnZhpUn4weB7gqFVo7CaBxn7v4VMtWC3anhreVMbs5zM/s320/IMG_3749.jpg" width="320" /></a></div>Here the nail plates that hold together the posts and headers can be seen. Not visible are the hurricane straps that are wrapped around and over the rafters and fastened to the outside of the header. Also in the picture, between the nail plates is the temporary blocking at the end of each rafter subassembly section that helps position it. This was key to the assembly process for a roof frame like this. To the right can be seen the upper pulley that was used to bring up each roof subassembly frame. This could not be brought up in the elevator because of their size.</div><div><br /></div><div class="separator" style="clear: both; text-align: center;"><a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEikPztuksFupaTLmh6-xnLWJ82mXO2eRj9hJ3NwFcXvqDetSNoBBvgHgKvD_f56ijO7uJV9NafuE3CNnXJrfpfl0Zn6oDYMJF31Y9yZntdgwJVuUr8-ylsGebw6B1Bvp7fYd8XotD8cRpY/s2048/IMG_3750.jpg" imageanchor="1" style="margin-left: 1em; margin-right: 1em;"><img border="0" data-original-height="1536" data-original-width="2048" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEikPztuksFupaTLmh6-xnLWJ82mXO2eRj9hJ3NwFcXvqDetSNoBBvgHgKvD_f56ijO7uJV9NafuE3CNnXJrfpfl0Zn6oDYMJF31Y9yZntdgwJVuUr8-ylsGebw6B1Bvp7fYd8XotD8cRpY/s320/IMG_3750.jpg" width="320" /></a></div>The rigging of a second class, moving pulley, made the task of lifting up each of the roof frame subassembly a snap. Two guide ropes were attached to the bottom corners of the frame and ran through junk brake rotors on the ground. These kept the frame from twisting around as they were raised to the top. Also the extra length of the sling from the pulley to the frame gave me the slack I needed to lift and twist the frame up onto the floor deck. Made the whole thing a one person process.<br /><div><br /></div><div><br /></div><div class="separator" style="clear: both; text-align: center;"><a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEhcETTp1Jv1hKP-tX9wYs0vp8pyqvKqyeysn3nMo-Zm4ywzK1yyboCeBakdnWophF2P3-fHNBJNUEBjNc8w6MEYgXqBIM6MyoNbDiGPNoQySXwPncVxu18D1ELYU_KgA0SkLnKijLQ9lHs/s2048/IMG_3751.jpg" imageanchor="1" style="margin-left: 1em; margin-right: 1em;"><img border="0" data-original-height="1536" data-original-width="2048" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEhcETTp1Jv1hKP-tX9wYs0vp8pyqvKqyeysn3nMo-Zm4ywzK1yyboCeBakdnWophF2P3-fHNBJNUEBjNc8w6MEYgXqBIM6MyoNbDiGPNoQySXwPncVxu18D1ELYU_KgA0SkLnKijLQ9lHs/s320/IMG_3751.jpg" width="320" /></a></div>Things are really starting to take shape now.

I decided to harness the top in two places with a cable then attach a sliding snatch block that could move along the harness as the assembly was raised. This would make two lifting points and take some of the stress off the rails during the lift. Not shown but, equally important was a set of come alongs attached to the bottom ends of the rails. These held the rails and prevented them from sliding forward as the assembled rail system was lifted. It did the job and worked very well.</div><div><br /></div><div><br /></div><div class="separator" style="clear: both; text-align: center;"><a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEjuLngBkcYydWt-m5MDb1kJi0rAYbpqBXXOb1q5lm9KWbIF0bZ0zMCzlZzH9ayfiTBZYUAV2Mfco5BRBe5vdfL8zKqgGDcXGEmgc8T6tILC0c9MEx6aJnAbjBYAPbaNbkBPU5xzXkDxxV8/s2048/IMG_3728.jpg" imageanchor="1" style="margin-left: 1em; margin-right: 1em;"><img border="0" data-original-height="1536" data-original-width="2048" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEjuLngBkcYydWt-m5MDb1kJi0rAYbpqBXXOb1q5lm9KWbIF0bZ0zMCzlZzH9ayfiTBZYUAV2Mfco5BRBe5vdfL8zKqgGDcXGEmgc8T6tILC0c9MEx6aJnAbjBYAPbaNbkBPU5xzXkDxxV8/s320/IMG_3728.jpg" width="320" /></a></div>A worm drive winch left over for a bridge raising was used to raise the rail assembly.

The last piece of flooring has to be left off for now to allow access so I can work on installing the elevator system.

Should be more fun than climbing the ladder.<br /><div><br /><div><br /><div><br /><p><br /></p></div></div></div>Dickhttp://www.blogger.com/profile/13870935149581761539noreply@blogger.com0tag:blogger.com,1999:blog-5754440625977916703.post-249768896705920882021-06-04T13:12:00.000-07:002021-06-04T13:12:54.261-07:00Treehouse packed and ready to roll<p> </p><div class="separator" style="clear: both; text-align: center;"><a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEjmFVHQuiShGjU2O-1o4xL6_NRBKw26okMmvx0I-_8Qvjyzpmvbcmoieq1iKhE7sdKy5R1qk4uqWolmuz4S2DoOZNTl328aZdr3jXnFGGNiknoHXmjdEYR5VwA5X5djytEbQKtagPQnycU/s2048/IMG_3686.jpg" imageanchor="1" style="margin-left: 1em; margin-right: 1em;"><img border="0" data-original-height="1536" data-original-width="2048" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEjmFVHQuiShGjU2O-1o4xL6_NRBKw26okMmvx0I-_8Qvjyzpmvbcmoieq1iKhE7sdKy5R1qk4uqWolmuz4S2DoOZNTl328aZdr3jXnFGGNiknoHXmjdEYR5VwA5X5djytEbQKtagPQnycU/s320/IMG_3686.jpg" width="320" /></a></div>The first step in dissembling the treehouse was to remove the hatch and rubber roof membrane. With this done I could begin to take off the roof sheathing. The upper portion of the treehouse would be stacked on the trailer shown on the left. The floor and floor framing would be put on another trailer.<p></p><div class="separator" style="clear: both; text-align: center;"><a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEgXCMUEKWDKC0FRxMBivVs4Y28TaTv8j6VzmUbSvBnCcwyWwZG6vmaepnDqfNh5pXM3-_W11xy3zdZ7nRPbHuG1akcNZ5cqx755lrE4VycacX9xdd6axqututPCNStlEE8dL-4XAxCBPaY/s2048/IMG_3685.jpg" imageanchor="1" style="margin-left: 1em; margin-right: 1em;"><img border="0" data-original-height="1536" data-original-width="2048" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEgXCMUEKWDKC0FRxMBivVs4Y28TaTv8j6VzmUbSvBnCcwyWwZG6vmaepnDqfNh5pXM3-_W11xy3zdZ7nRPbHuG1akcNZ5cqx755lrE4VycacX9xdd6axqututPCNStlEE8dL-4XAxCBPaY/s320/IMG_3685.jpg" width="320" /></a></div>With projects like this it is best and easiest to do any painting or staining before you assemble the project. So here are the roof sheets laid out in the shed where I could roller on a nice coat of white paint for the ceiling. The same treatment was given to the bottom side of the sheets of plywood flooring.<div><br /></div><div class="separator" style="clear: both; text-align: center;"><a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEjl96hQJs8UfuqMdg_5kSGKEukMMK2MHQG7D2EGbObttLEbq_AGv046-2W0gKQhykGmusw2OIHkrGJxY8dsLqcwVI1pgX4m9vmxmj-uCiQxOaPvEMqCXOh9Hh4eLPuc7AAU-Vycu1kRi40/s2048/IMG_3687.jpg" imageanchor="1" style="margin-left: 1em; margin-right: 1em;"><img border="0" data-original-height="1536" data-original-width="2048" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEjl96hQJs8UfuqMdg_5kSGKEukMMK2MHQG7D2EGbObttLEbq_AGv046-2W0gKQhykGmusw2OIHkrGJxY8dsLqcwVI1pgX4m9vmxmj-uCiQxOaPvEMqCXOh9Hh4eLPuc7AAU-Vycu1kRi40/s320/IMG_3687.jpg" width="320" /></a></div>So with the roof sheathing removed it was time to think about the rafters and how they might be kept in some sort of sub-assembly. The solution was to add a second set of block stops to the mid rafters. Then I also installed three leg supports on the center plug and marked their location on the floor.<div><br /></div><div><div class="separator" style="clear: both; text-align: center;"><a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEjj3naunlAjadUr46ZKCWpclVtG-PCvVeaiGTTVrtFsGlXDI576DPFyFF9PYmbhqMKGco9c47NYNz1OBySFgA0ar8Iq4uq1DDr7_4hJDwQQGI57_A2b09IoQNsIrKo-pU_sjF6ExRt3Zk4/s2048/IMG_3689.jpg" imageanchor="1" style="margin-left: 1em; margin-right: 1em;"><img border="0" data-original-height="1536" data-original-width="2048" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEjj3naunlAjadUr46ZKCWpclVtG-PCvVeaiGTTVrtFsGlXDI576DPFyFF9PYmbhqMKGco9c47NYNz1OBySFgA0ar8Iq4uq1DDr7_4hJDwQQGI57_A2b09IoQNsIrKo-pU_sjF6ExRt3Zk4/s320/IMG_3689.jpg" width="320" /></a></div>Each set of primary and secondary rafters would be screwed together at the top. Then one end of the fascia would be unscrewed, leaving it attached to the lower ends of the primary/secondary pair. This triangular segment was then removed.</div><div><br /></div><div class="separator" style="clear: both; text-align: center;"><a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEh6r1WGkNdeODjxfLB1Gv1l56O9sjKfxMJZ9W3E7RSJpHVYNmrS21NVqVh0hDz6oS8vgebuLrn92GxEECujCZqw_Lh1L3ygD1vLRyjVvObjzof8QJjM7-leRa9YrGVmtWNyRcUlK8-2294/s2048/IMG_3688.jpg" imageanchor="1" style="margin-left: 1em; margin-right: 1em;"><img border="0" data-original-height="1536" data-original-width="2048" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEh6r1WGkNdeODjxfLB1Gv1l56O9sjKfxMJZ9W3E7RSJpHVYNmrS21NVqVh0hDz6oS8vgebuLrn92GxEECujCZqw_Lh1L3ygD1vLRyjVvObjzof8QJjM7-leRa9YrGVmtWNyRcUlK8-2294/s320/IMG_3688.jpg" width="320" /></a></div><div>This unit, one of six was easy to remove.

As there is no running water at the cabin I would need to bring in my own supply. This would be done by filling a 30 gallon garbage can in the truck then using a fountain pump to transfer the water to the two milk cans. The mighty mixer was a labor saver that would mix the batches of premixed mortar. About half a bag at a time. All I had to do was add water and turn it on! Not knowing how many 80 pound bags of mortar I would need I ordered a full "cube" 40 bags! Yikes that was 3,200 pounds for a 1/2 ton truck.<div><br /></div><div class="separator" style="clear: both; text-align: center;"><a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEhTlf4XYQ8Vf3EQPrX7syoRQol08gcmHgb3dK3ROqxXYONh0T4BXQOsxkD5pGT9H20hFN2DNBj9VT0NIPaDlG_U6py4lcGlhoVlOnJSgs5cCJ8hYMic5l2LlBzHhIcHMLlNuEf1olITihs/s2048/IMG_3647.jpg" imageanchor="1" style="margin-left: 1em; margin-right: 1em;"><img border="0" data-original-height="1536" data-original-width="2048" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEhTlf4XYQ8Vf3EQPrX7syoRQol08gcmHgb3dK3ROqxXYONh0T4BXQOsxkD5pGT9H20hFN2DNBj9VT0NIPaDlG_U6py4lcGlhoVlOnJSgs5cCJ8hYMic5l2LlBzHhIcHMLlNuEf1olITihs/s320/IMG_3647.jpg" width="320" /></a></div><div>Some of the gaps between logs were pretty wide and required the placement of a strip of wire lath to be inserted to hold the first coarse of mortar as shown here. </div><div><br /></div><div class="separator" style="clear: both; text-align: center;"><a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEiXBCwvf1pxjoG9m_a2IEgZM5Z0yoyLAfLvffuzNs7UVFaQZFdKeJwMC6y92ux8L7PGwAEtvG1BpLLlLlE9_WE_ZWoL2qOEnfZADvCm1oc4ZIui7SJ3tr4ZbJLgG4vpyzUYEecAlFtudCc/s2048/IMG_3646.jpg" imageanchor="1" style="margin-left: 1em; margin-right: 1em;"><img border="0" data-original-height="1536" data-original-width="2048" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEiXBCwvf1pxjoG9m_a2IEgZM5Z0yoyLAfLvffuzNs7UVFaQZFdKeJwMC6y92ux8L7PGwAEtvG1BpLLlLlE9_WE_ZWoL2qOEnfZADvCm1oc4ZIui7SJ3tr4ZbJLgG4vpyzUYEecAlFtudCc/s320/IMG_3646.jpg" width="320" /></a></div>This had to be done on about 3/4's of all the logs, inside and out! Note: 12 by 14 cabin = 52 foot perimeter times 12 logs high = 624 linear feet x 2 (inside and out) = 1,248 feet.

The design of the mortar joint is such that the top edge of the mortar is pressed back at the top and then brought out to the edge of of the log below it. Doing this forms a drip edge at the top and a slope that sheds the water off the log below. This is super important for the life of the logs and cabin. <div><br /></div><div> <div class="separator" style="clear: both; text-align: center;"><a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEg4DqQ3RBGMq7VXVnYeAJXDaVHNiIBSIgnNCIcikSgx_qg9vQrxalXRT-aQ47dt18ByPcgsKq9WwnKdB1XisiNH1lRz4onh1biViMbiBJEjYGLOOWNmM1BF9ycnsVqU_LZ3ybVJfQt8KLc/s2048/IMG_3670.jpg" imageanchor="1" style="margin-left: 1em; margin-right: 1em;"><img border="0" data-original-height="1536" data-original-width="2048" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEg4DqQ3RBGMq7VXVnYeAJXDaVHNiIBSIgnNCIcikSgx_qg9vQrxalXRT-aQ47dt18ByPcgsKq9WwnKdB1XisiNH1lRz4onh1biViMbiBJEjYGLOOWNmM1BF9ycnsVqU_LZ3ybVJfQt8KLc/s320/IMG_3670.jpg" width="320" /></a></div></div><div>So this is what it looks like after it is cleaned up with a scraper and wire brush to remove any excess mortar from the log surfaces.

Fortunately this Oak tree is dead so I did not have to keep the health of a living tree in mind when I attached the supporting beams to the tree. <p></p><div class="separator" style="clear: both; text-align: center;"><a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEiMuGfb7wDUrGkfRwpDbpAFYcfvZ6Jab0pTobzh8UVmHHI0W5AtPO4yBRdXZH7NOS4cau-aU9iEyG0ishIBg7LGux2zJhqDNkin6rwgJHBzhlqghiyg0JSnFAa_7DNc_c5n-3msaXaGawk/s2048/IMG_3653.jpg" imageanchor="1" style="margin-left: 1em; margin-right: 1em;"><img border="0" data-original-height="1536" data-original-width="2048" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEiMuGfb7wDUrGkfRwpDbpAFYcfvZ6Jab0pTobzh8UVmHHI0W5AtPO4yBRdXZH7NOS4cau-aU9iEyG0ishIBg7LGux2zJhqDNkin6rwgJHBzhlqghiyg0JSnFAa_7DNc_c5n-3msaXaGawk/s320/IMG_3653.jpg" width="320" /></a></div>Beam material would be 2 by 8 rough sawn Oak plank. Since the pieces I had were not 10 feet long I needed to lap and screw two pieces together. This would not be a problem as each beam was going to be supported in two places about 2 feet from their center point by the 1 foot diameter tree limbs in the crotch of the tree.<div><br /></div><div class="separator" style="clear: both; text-align: center;"><a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEhJ3pEGwZ8Npiprxd-5fyP06lK-RfqyvC2RCtInLXd_fdW7YXySmnGXTbyuo0876zDKcBxskUHbXkndgvkvmc3iWc4O65yf0fxupBpv6-JJ44JnuKHMMKopI4ycs2km2ge-YeGAC0EmruE/s2048/IMG_3661.jpg" imageanchor="1" style="margin-left: 1em; margin-right: 1em;"><img border="0" data-original-height="1536" data-original-width="2048" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEhJ3pEGwZ8Npiprxd-5fyP06lK-RfqyvC2RCtInLXd_fdW7YXySmnGXTbyuo0876zDKcBxskUHbXkndgvkvmc3iWc4O65yf0fxupBpv6-JJ44JnuKHMMKopI4ycs2km2ge-YeGAC0EmruE/s320/IMG_3661.jpg" width="320" /></a></div>Doing all this from 30 feet in the air was not going to be for the faint of heart.

You can see the braces on the model. A change in the elevator design shortened the length of the beam shown on the model by about 3 feet so it will not be sticking out that far to the left.<div><br /></div><div class="separator" style="clear: both; text-align: center;"><a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEgN14Pj1JVTTX5yrSlHgHANmq4j58bEaUJFbZFZpxhgsWZmNnFSIXZECLDRtPNpF-bm4HQTujPtC7YwKZphTqLCvK_WTBgJQjRgAZ-U2Y7NBkhOC1O0hD1KqBnmeTDIbU4RHywKvmG6Efs/s2048/IMG_3654.jpg" imageanchor="1" style="margin-left: 1em; margin-right: 1em;"><img border="0" data-original-height="1536" data-original-width="2048" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEgN14Pj1JVTTX5yrSlHgHANmq4j58bEaUJFbZFZpxhgsWZmNnFSIXZECLDRtPNpF-bm4HQTujPtC7YwKZphTqLCvK_WTBgJQjRgAZ-U2Y7NBkhOC1O0hD1KqBnmeTDIbU4RHywKvmG6Efs/s320/IMG_3654.jpg" width="320" /></a></div>OK, the first two main beams, shown running from left to right were notched into the tree. The notch gave the beam a positive support point that would carry the load and would only need screws to hold them in place. Rubber roof membrane was placed over the exposed end grain of each notch to keep out any water. Although I don't see this as being much of a problem as the finished Treehouse will be covering this area.<div><br /><div>You can see the ladder has been extended by clamping a section of aluminum ladder to my 24 foot fiberglass extension ladder. This got me right to the crotch of the tree and eliminated the need to climb the 2x4 steps screwed to the tree. It also brought visions of a poster I saw in a local business showing various jury rigged things like this and was titled, "Why Women Live Longer Than Men!"</div><div><br /></div><div>With the first two main beams in place a center mast was installed that provided two attachment points. One for the rope and pulley to bring up tools and materials until the elevator is in operation and a second point for a safety harness line. This point was offset and can swivel so I can work around the perimeter of the Treehouse and not get wrapped up like a dog on a chain.</div><div><br /></div><div>You can also see the first of the four diagonal braces hanging from a second level support beam.</div><div><br /></div><div class="separator" style="clear: both; text-align: center;"><a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEjORiaO8UQCDRKLAyzzauR_6sCFU6OFuTo6B3SlG5uhjr9l7DvztRxDOp1imCbw7uKjZjWcFREFcWgDslY1XsD4Ns-7tsTWxWKgEi52r8vTZvtupRDDY0fD3WP4SsQ-1YTbVMYVJLOGJzA/s2048/IMG_3655.jpg" imageanchor="1" style="margin-left: 1em; margin-right: 1em;"><img border="0" data-original-height="1536" data-original-width="2048" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEjORiaO8UQCDRKLAyzzauR_6sCFU6OFuTo6B3SlG5uhjr9l7DvztRxDOp1imCbw7uKjZjWcFREFcWgDslY1XsD4Ns-7tsTWxWKgEi52r8vTZvtupRDDY0fD3WP4SsQ-1YTbVMYVJLOGJzA/s320/IMG_3655.jpg" width="320" /></a></div>Things are moving right along now.

I know the tree trunk could stand it because it survived the wind storm that tore away the massive tree top several years ago. I needed to make sure those forces, should they occur again not knock out the Treehouse and send it crashing to the ground. Or worse land on Cabin #6! To accomplish this each of the second level beams, crossing at right angles to the main beams were tied together with ready bolts and plates like this.<div><br /></div><div class="separator" style="clear: both; text-align: center;"><a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEg5uFRxdylLuc9BhI2_30fMvXZ19J_DoJxjdavj_S8XXw8nkXAjVLOS3LeXRC_PoWiXRg_LxCbIX0T9q9RHdfgNrys1plJu3dNI00UBTRzdiAyuxyZoACX5rhv2xCKlEb9Lmqa0vJDWuDc/s2048/IMG_3663.jpg" imageanchor="1" style="margin-left: 1em; margin-right: 1em;"><img border="0" data-original-height="1536" data-original-width="2048" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEg5uFRxdylLuc9BhI2_30fMvXZ19J_DoJxjdavj_S8XXw8nkXAjVLOS3LeXRC_PoWiXRg_LxCbIX0T9q9RHdfgNrys1plJu3dNI00UBTRzdiAyuxyZoACX5rhv2xCKlEb9Lmqa0vJDWuDc/s320/IMG_3663.jpg" width="320" /></a></div>So all this might look easy but I can tell you a project like this keeps you on your feet and there are plenty of things to consider if the outcome you want is to be square and level like this.

Pictured is the model of the structure that I am talking about. This will be tricky in the beginning as there will be little to secure safety ropes to and the ropes will also be below the level of work I am doing for the start. <p></p><p><br /></p><div class="separator" style="clear: both; text-align: center;"><a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEitrpmkG8M71nN-qfonuOPftLi9Z6qNIxe36bq3AIWYt2Ll3qS4ajA7ykcplvMO7nPrBUgXhMhMHaY4lsNvAh00l8LCg82naZeZWxaRIHF71IHVTdzEo9J7erAnMUuODDknqEpMtHRcV_4/s2048/IMG_3642.jpg" imageanchor="1" style="margin-left: 1em; margin-right: 1em;"><img border="0" data-original-height="1536" data-original-width="2048" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEitrpmkG8M71nN-qfonuOPftLi9Z6qNIxe36bq3AIWYt2Ll3qS4ajA7ykcplvMO7nPrBUgXhMhMHaY4lsNvAh00l8LCg82naZeZWxaRIHF71IHVTdzEo9J7erAnMUuODDknqEpMtHRcV_4/s320/IMG_3642.jpg" width="320" /></a></div>OK, three hours later the first board is up and secured in place. In preparation for this the extension ladder was placed and tied off at the top to the tree. Then the lad slide rope was attached, as high as I could reach, to the limb on the right with the climbing steps. With the climbing harness on this allowed me to safely go up and down the rope to this point. Now the picture doesn't show it but the climbing steps lean a few degrees out from vertical. This causes a bit of anxiety. I then taused two more rope slings through the crotch at the top and secured them. This gave two more points to attach my safety harness leads as I moved up. Being cautious always to be secured by three points as I climbed.<div><br /></div><div>One of the main concerns in this project is how the 1675 pounds of Treehouse dead weight will be distributed. This first support is a 2.5" by 8" piece of rough sawn Oak. The tree trunk was notched to form a flat support for each end and the piece was secured to the tree with four 1/4 by 6" GRK screws. Also as an extra precaution against rotting a piece of rubber menbrane material was placed one the end grain of the notch area on the tree. </div><div><br /></div><div>So now the safety rope for the lad slide is secured to the top of the highest point on the left limb and I will get to work on the putting up the second main support piece in the same fashion.

The process of chinking has begun. This required a work station for mixing the mortar that will be used for the job. As there is no running water at the cabin and the mortar will be stored outside this all had to be planned for as the chinking process will take several weeks.<div><br /></div><div class="separator" style="clear: both; text-align: center;"><a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEgsNVKmImk6oTRVSPTaxyglL3hkFXuKAWRRO2NYI7Lz63mwnRv1X2VObxdLrpoI4jt1hu0qaAnAo5di4uDjXtjE0T1t_DGTuWFYU8enadzKCxcZWUagXzjiWyTBkA8P2BatKrWoLcakKn0/s2048/IMG_3644.jpg" imageanchor="1" style="margin-left: 1em; margin-right: 1em;"><img border="0" data-original-height="1536" data-original-width="2048" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEgsNVKmImk6oTRVSPTaxyglL3hkFXuKAWRRO2NYI7Lz63mwnRv1X2VObxdLrpoI4jt1hu0qaAnAo5di4uDjXtjE0T1t_DGTuWFYU8enadzKCxcZWUagXzjiWyTBkA8P2BatKrWoLcakKn0/s320/IMG_3644.jpg" width="320" /></a></div>Fired up my trusty new mixer and it is perfect for the job. Making a 5 gallon bucket full of mortar mix per batch is just right. The mortar is a colored pre-mix having all the sand, lime and mortar in it. All I need to do is add water and mix.<div><br /></div><div class="separator" style="clear: both; text-align: center;"><a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEhBWT8yeMBP_xSiDa448d7DQVVO_Vb04ENBAjRTN7HqbWxspPpZVN-Qbk9OHSMhL3dvIKSy7Q40QmCp5TXQe9t8IKl0FClJYX44LSRU5dYy_am4GBeHNm_PWIDVJTAMzuJQUK9_JXBlNWU/s2048/IMG_3645.jpg" imageanchor="1" style="margin-left: 1em; margin-right: 1em;"><img border="0" data-original-height="1536" data-original-width="2048" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEhBWT8yeMBP_xSiDa448d7DQVVO_Vb04ENBAjRTN7HqbWxspPpZVN-Qbk9OHSMhL3dvIKSy7Q40QmCp5TXQe9t8IKl0FClJYX44LSRU5dYy_am4GBeHNm_PWIDVJTAMzuJQUK9_JXBlNWU/s320/IMG_3645.jpg" width="320" /></a></div><br /><div>Chinking, first go at it. Will practice on the back and outside of the cabin to get the hang of it. Some of the larger gaps have wire lath in them but either way it is going to take at least two layers of mortar to fill in the gaps in most places. On the outside it is important to run the mortar so that the top edge is under the edge of the top log by about 1/2 inch and then runs out to the very edge of the bottom log. This make the top log a drip edge and prevents the water running down the wall from being able to get behind the mortar joint to rot the logs. This is an important detail in the chinking process!</div><div><br /></div><div class="separator" style="clear: both; text-align: center;"><a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEgOVo0vID11MCRrYaDXqbQfhMMme457g5cHbMocjL7g1ZuD3t1c6JT2ox0E_XuGCHpJEdTF2snkEVxZo_OKYniu9eSKOq8sJ8sUjywpxrKg0OuIQGi0QYfoGJHZ43c4_roWv_Fnlegdbfo/s2048/IMG_3646.jpg" imageanchor="1" style="margin-left: 1em; margin-right: 1em;"><img border="0" data-original-height="1536" data-original-width="2048" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEgOVo0vID11MCRrYaDXqbQfhMMme457g5cHbMocjL7g1ZuD3t1c6JT2ox0E_XuGCHpJEdTF2snkEVxZo_OKYniu9eSKOq8sJ8sUjywpxrKg0OuIQGi0QYfoGJHZ43c4_roWv_Fnlegdbfo/s320/IMG_3646.jpg" width="320" /></a></div>So after a couple of hours and 2.5 bags of mortar the back outside wall has the first layer of mortar in it.<br /><div><br /></div><div><br /></div><div><br /></div><div><br /></div><div><br /></div><div><br /></div><div> <br /><div><br /><div><br /></div><div><br /><div><br /></div><div><br /><div><br /></div><div><br /></div><div><br /></div><div><br /></div><div> <br /><p><br /></p></div></div></div></div></div>Dickhttp://www.blogger.com/profile/13870935149581761539noreply@blogger.com0tag:blogger.com,1999:blog-5754440625977916703.post-29533587193439907482021-05-01T17:19:00.001-07:002021-05-01T17:19:15.424-07:00Window and Parts Delivery System<p> </p><div class="separator" style="clear: both; text-align: center;"><a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEiVvGDpCITS9dkNBialV-PZxbyDIKmXvpFcye21NTGfsuvIaINuXyoz3g0u48JTpZN3QyGZj5pzMF_VRvtyEJc48cDPPEp6ALZYA3ZoOyOU8EGMQKjzgcYOfTiT18eB-Y4IajiPEO1K-7s/s2048/IMG_3628.jpg" imageanchor="1" style="margin-left: 1em; margin-right: 1em;"><img border="0" data-original-height="1536" data-original-width="2048" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEiVvGDpCITS9dkNBialV-PZxbyDIKmXvpFcye21NTGfsuvIaINuXyoz3g0u48JTpZN3QyGZj5pzMF_VRvtyEJc48cDPPEp6ALZYA3ZoOyOU8EGMQKjzgcYOfTiT18eB-Y4IajiPEO1K-7s/s320/IMG_3628.jpg" width="320" /></a></div>Would a window for the treehouse even fit through the opening?

Measuring from Point to Point of the hexagon was around 18' because of the diagonal of the right triangle roof pieces. So the direction to run the roof material and which edge to start with was determined. The area of the roof hatch would be where the gathering of the 100 pound membrane piece would take place. <div><br /></div><div class="separator" style="clear: both; text-align: center;"><a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEiNTb34Sk7lFjwaL7aIl52BIykJP7-ie6olyCjYhERe7PjMy12biBW6kLkS8BxpAUskoEU3v5ht5F8XtWJW2N588r5OvgcS9fA8QUGCPI9Rvamc9K1IF66ZRt0oywDZoTHe46PmcY_zpJ4/s2048/IMG_3638.jpg" imageanchor="1" style="margin-left: 1em; margin-right: 1em;"><img border="0" data-original-height="1536" data-original-width="2048" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEiNTb34Sk7lFjwaL7aIl52BIykJP7-ie6olyCjYhERe7PjMy12biBW6kLkS8BxpAUskoEU3v5ht5F8XtWJW2N588r5OvgcS9fA8QUGCPI9Rvamc9K1IF66ZRt0oywDZoTHe46PmcY_zpJ4/s320/IMG_3638.jpg" width="320" /></a></div>OK.

This required a bit of construction but will do the job nicely. It also provided the extra height I needed to get the hoist in place and if I ever needed to service the hoist I could get at it. The roof vent will also be placed within reach of the hatch opening should there ever be a leak there.

I had "planned" to do all the construction in my pole shed but the shed roof trusses were in the way of the Treehouse roof rafters. So I was left with no choice but to move it out. Would it go through the garage door opening? The thought brought back a memory of articles read long ago where someone had built an airplane in their basement only to realize that there was no way to get the finished plane out. Would I be suffering a similar fate?<p></p><div class="separator" style="clear: both; text-align: center;"><a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEhaSMwFJGd6NwVCwMLlfLHiiHrWHTG_ZmaocAhSjnml5MNlyhFZgq-866M5C_bzIIAyRT-m3qhBNAe4uhVVbrjqv19OavKQw4qK92FlMQWo-OxRKNvEPOnZ67XsLwzzCRcZXGuiNsrNXbE/s2048/IMG_3580.jpg" imageanchor="1" style="margin-left: 1em; margin-right: 1em;"><img border="0" data-original-height="1536" data-original-width="2048" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEhaSMwFJGd6NwVCwMLlfLHiiHrWHTG_ZmaocAhSjnml5MNlyhFZgq-866M5C_bzIIAyRT-m3qhBNAe4uhVVbrjqv19OavKQw4qK92FlMQWo-OxRKNvEPOnZ67XsLwzzCRcZXGuiNsrNXbE/s320/IMG_3580.jpg" width="320" /></a></div>As they say, "One more coat of paint and it would not have fit through the door."

Two 2x6's are attached on edge to the hexagon post on the right. This is a temporary set-up just to test the proof of concept. The real ones will have a 2x4 stiffeners screwed to the back side forming a T for strength. Two pieces of garage door track are screwed to each 2x6. Garage door rollers are placed at the top and bottom of the cage. The hoist is squeezed into the soffit area just above the door. With 5 foot windows, and using one of them as a door there is a challenge in getting head clearance. This is solved by the elevator stopping 16 inches below the floor of the Treehouse. You can see the cement block in the bottom of the elevator. This represents the "step up" to get into the 5 foot high opening to the Treehouse. Likewise when exiting the Treehouse you step down and your head clears the top header. It works like a charm. Unless you are over 6 feet tall!</div><div><br /></div><div class="separator" style="clear: both; text-align: center;"><a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEhvN6IB82pdQsrfP8Vl_ayt8RSUHzDH2wGP6yIhGsv6JHVogTTxHtvzlaHPxwr0noQ5EwVa5PlpkmoiLXj1eSPHcxE7PwPc5TSu528B7gG9DBnOBswiZQa10h-gMlqDaSAqfWZF_DLT4y4/s2048/IMG_3599.jpg" imageanchor="1" style="margin-left: 1em; margin-right: 1em;"><img border="0" data-original-height="1536" data-original-width="2048" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEhvN6IB82pdQsrfP8Vl_ayt8RSUHzDH2wGP6yIhGsv6JHVogTTxHtvzlaHPxwr0noQ5EwVa5PlpkmoiLXj1eSPHcxE7PwPc5TSu528B7gG9DBnOBswiZQa10h-gMlqDaSAqfWZF_DLT4y4/s320/IMG_3599.jpg" width="320" /></a></div>Here is a look at it from the inside. The top of the elevator stops at the bottom of the header. On exit you step down 6" to get into the elevator and avoid a "header". A recoil with inertia safety cable will be attached to the elevator frame and roof rafter as a fail safe should the cable snap. <div><br /></div><div>So next it will be on to finishing up the roof rafter attachments and placing some cable ties to strengthen up the roof system to hold the load of the roof sheathing. Tricky but doable.<br /><div><br /></div><div><br /></div><div><br /></div><div><br /></div><div><br /></div><div><br /></div><div><br /></div><div><br /></div><div><br /></div><div><div><br /><div><br /></div><div><br /></div><div><br /></div><div><br /><p><br /></p></div></div></div></div>Dickhttp://www.blogger.com/profile/13870935149581761539noreply@blogger.com0tag:blogger.com,1999:blog-5754440625977916703.post-89419863250841522552021-04-15T18:12:00.000-07:002021-04-15T18:12:33.031-07:00Treehouse main frame complete<p> </p><div class="separator" style="clear: both; text-align: center;"><a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEiEOwp2lxJQXCWbIAGJVNCexc0fGuXE779f_cmnTyj37Dket9cxII_DZlDbiFn9HTKtN5nCAYSFD7T_OszOOtf95rUZOxmF2iASyyHBqJ9E6KmP4TVoZb1XONbMTzFT1Fk_F1PTPNwEZBw/s2048/IMG_3569.jpg" imageanchor="1" style="margin-left: 1em; margin-right: 1em;"><img border="0" data-original-height="1536" data-original-width="2048" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEiEOwp2lxJQXCWbIAGJVNCexc0fGuXE779f_cmnTyj37Dket9cxII_DZlDbiFn9HTKtN5nCAYSFD7T_OszOOtf95rUZOxmF2iASyyHBqJ9E6KmP4TVoZb1XONbMTzFT1Fk_F1PTPNwEZBw/s320/IMG_3569.jpg" width="320" /></a><span style="text-align: left;">So with some head scratching I came up with this orientation for the 3/4 BCX flooring.

Before there was a 2x4 held with pocket screws placed between the posts. This was needed to provide wood for the top nail flange of the window. The top 2x12 was then lapped inside each post. This sandwiched the window flange. Bad design. The new design called for the top 2x12 to be butt between the posts. A nail plate was screwed to the inside and this worked well.<div><br /></div><div class="separator" style="clear: both; text-align: center;"><a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEhV6nPrlkfDwbu1JOvKWWBX49N9lUqr7lnxElhWCMrJXX0qluQ4GzsxGf6ODbqi-yg_P0le6g8yxNTAK3ept-_le8jT4L_58wOAh0cSZwJSJt6GerWLHWE8xeQoOCayklbWNS78OyywL_Y/s2048/IMG_3573.jpg" imageanchor="1" style="margin-left: 1em; margin-right: 1em;"><img border="0" data-original-height="1536" data-original-width="2048" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEhV6nPrlkfDwbu1JOvKWWBX49N9lUqr7lnxElhWCMrJXX0qluQ4GzsxGf6ODbqi-yg_P0le6g8yxNTAK3ept-_le8jT4L_58wOAh0cSZwJSJt6GerWLHWE8xeQoOCayklbWNS78OyywL_Y/s320/IMG_3573.jpg" width="320" /></a></div><br /><div>And there you have it. Weighing in at 995 pounds of main frame. Now I will go to work building the elevator frame. With elevator frame I can better gauge the pitch of the roof to get the overhang that will work best to handle the winch placement.<br /><div><br /><p><br /></p></div></div>Dickhttp://www.blogger.com/profile/13870935149581761539noreply@blogger.com0
