Re: what did you do to your motorized bicycle today?
So cool GN! When I was in school, the instructor was showing us a Bridgeport mill. To change tool speed/gear ratio, you turn a dial. He had no idea why I got so excited about that but instead of changing the belt ratio by hand as you would on a drill press, ya dial it. Would work exactly like what your wanting to do.
Dangit, now your gonna beat me to it, eh? lol
Would be wide but perfect for our thing.
