I've been thinking about both a belt grinder and a bead roller but haven't pulled the trigger. I'm interested to hear more from others too. The most critical tool is the belt grinder. I was thinking to possibly do one of the DIY kits like the knife makers do. A like to an example is below. Anyone ever built and used one of these??
