I bought a cheap wood lathe from a friend to start getting into turning. It has 4 speeds, but the lowest speed does not seem to spin any of the pieces at all. I'm wondering if anyone has worked with this lathe or any other lathe where the belt has to be moved for different speeds. Does tension or anything else play into the motor not spinning correctly at certain speeds. I can get it to work fine at the two highest speeds, but trying to rough turn a log of a bowl at those speeds is terrifying. I'd rather keep my face and appendages in tact.
