Yesterday I cut Frame #2.
The bottom members are relatively easy as they are pretty much just 3" boards. Of course I managed to mess up the end of one of them. It's just not square. However this time I made the cut about 1/8" away from line so that I could tidy it up with a block plane afterwards. So now instead of moaning about ruining another board, I'm off to sharpen my planes.
Maybe, just maybe I'm learning.
