Puzzle box update

Last night I was using my stationary belt sander and a 50 grit belt to sand off and smooth most of the new block for the second attempt at the puzzle box. I sanded 5 of the six sides. The sixth side is to be trimmed in a miter saw first, then sanded. While sanding, I accidentally sanded off some skin on the knuckle of my left thumb. It will grow back fine, but smarts right now. The block looks really nice and has some interesting grain. Will move to a random orbit sander next.
