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.
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. You can see the sloping detail of each joint at the edge of the window frame.
Almost done with 1/8 th of the cabin.
The final step for the outside is to give the logs and mortar one last coat of the Honey Gold finish.
Then, while the cabin is drying it will be time to get back to work on the Treehouse Project. Here is the electrical service that I ran out from the cabin to the tree.

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!"
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.
You can also see the first of the four diagonal braces hanging from a second level support beam.
Oh wow, went as planned, so far so good.
Next up, Phase V Disassembly of the Treehouse and Placing the Floor.

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.
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. In the mean time...
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!

So I designed a temporary platform with some 2x4's and scrap flooring that will serve as the base to place parts and windows on to be lifted up to the treehouse for assembly.
So windows will be brought up then layed on the floor and tipped up from the inside and mounted. This method works like a charm and only the bottom nailing flange needs to be done on the outside with the window slid open.
