I am currently working on a project that has really pushed me. I am cuttting all of the joinery by hand and the dovetails are at 86/94 degree bevels instead of 90. This particular joint was the 5th of 6 and while starting to test fit it, i realized it was going to go together without modifying it. As far as woodworking goes it is about the best feeling in the world!!
