Finishing the second layer
Okay, this strip I cut purposely long so that I knew I could fit the end exactly. After you have brought the end around to the overlap. tranfer a line from the end of the underneath piece to the top piece. Cut this very carefully by hand. I use a sharp razor knife and a speed square to just keep cutting a layer at a time till it falls off. After you get through this, it will still be too tight. One piece will be slightly over the top. Using a hacksaw blade cut flush next to the top piece to the bottom piece. Don't cut through the first layer! The thickness of the sawblade will give you a perfect butt-up on the top layer. Glue these two pieces down and clamp overnight. Ta-da! You are done!
