Abstract
A multi-speed drive system for a portable lathe is disclosed wherein two or more input drive gears are utilized to drive a cutting tool holder ring. Each of the input drive gears has a different pitch diameter so that it will impart different drive speeds/torque characteristics to the cutting tool holder ring. A main drive gear is interposed between each of the input drive gears and a ring gear attached to the cutting tool holder. The input drive gears are each engaged with the main drive gear and a drive motor is connected to the desired input drive gear.
