The logs for round two of the cabin are completed. This was a good chance to fine tune the process of calculating, scribing and cutting the saddle notches to the correct depth so the tops of the logs for even numbered rounds will be at the same height. Looks easy enough, right? But when you think about it the logs are tapered and different diameters on the ends, maybe not.
And if all goes well this is what you get. All four corners at a height of between 21" and 22" with a minimum 3" wide groove making contact with the log below it. When the EM Seal expands in the groove the joint will be air tight.
With the new school year starting this brings to mind the old saying about learning and it applies here for sure. "I hear it I forget. I see it I remember. I do it, I understand!"

I almost forgot how much work was involved in the "process". Chop the saddle, position log, calculate rough notch, chop rough notch, scribe finish notch, saw edges, chop, re-sawing and fitting logs to build the walls. But it would all came back to me during the next eight hours it took me to do it!
