Here are a few photo’s of the process of bracing the back.

I probably used too thick of braces, either that or they aren’t tall enough. They are more triangle shaped than pillar shaped. During the shaping process, I slipped a lot with the chisel and took chunks out of the back. So I have a significant amount of sanding to do. At least I didn’t slip and take chunks out of my hand… I can’t sand that out.
