    I use a 1640 RPM motor with a 4 step pulley. I use the smallest step for polishing, I’m guesstimating about 250 rpm. I use the next to largest step for cutting, guesstimating 850 rpm? Somewhere in my tool pile I have an optical timing light (for measuring rpm on diesel motors), as soon as I find it I will update with accurate speeds.
