Way to go, Bubba. Looks like it chops pretty well as it is. I got a 1" X 24" el cheapo belt sander last year. Practiced on cheap machetes. Took all safety guards as stuff off of it so I could use the whole belt and get wide blades into it. I do it totally free-hand. So far, I have managed to make some nice convex edges. Got to have some slack in the belt to do it right. I'm not a machinist, so you might do better listening to a pro. I got a Dog Father coming soon!
