I got to wondering today if it would be possible to use one of those foot pedal operated variable speed controls (the ones marketed for router use) on a belt/disc sander. I've got a Delta Sanding Center 12" disc, 6x48" belt combo. Is this motor burnout problems waiting to happen? I was originally pondering this for low-speed (and temp) sharpening but think it would also be an advantage for better controlling the amount of wood removal for fine sanding.
Any thoughts?
