Real progress is being made now and I will have to change gears in my thinking as I plan and layout the half dovetail joints for the cabin.
Square Pegs in Round holes? Glad you asked.
Since we are building the cabin on "spec" and hope that a buyer can be found when it is finished I needed to come up with a solution that will secure the log ends but allow for easier removal than actual 7/8" Oak pegs. Trust me when I tell you that you don't just drive out a 7/8" Oak trunnel from an Oak log! These babies really hold once they are driven in.
So I figured, drilling a 7/8" (.875") diameter hole and then calculated (.875" x .707) that a .618" square peg would fit! I ripped some scrap pine making 5/8" square pegs to fit my round holes! They hold nicely and can be easily sawn off and driven out when I dis-assemble the finished cabin for delivery and re-assembly.
Maybe this is where the saying about square pegs and round holes comes from?
