Here's a belt grinder I made up, it takes 730x25 belts, which I chose because the grits available vary from 80 od to 1000. Originally the design was a three wheeler and there were two belts but the motor didn't have enough power to spin them, so I came up with this two wheel design. It's used for sharpening drills and lathe bits. When I come across a more powerful motor I'll ad another belt rub.
