Hello Rayh, the lathe has only 4 speeds and two directions, that makes 6 clutches. It's sure a nice feature squaring off - I'm usually turning by hand - to turn her up as it goes toward the center. She runs up to 2000 per minute. You change gears by rotating the engaging lever. There have been larger models of this brand, maybe with more gears, but they aren't produced anymore. Graziano was bought by Deckel and Deckel was bought by MAHO and MAHO was bought by Gildemeister.... In addition, I've put a VFD in the supply line to the motor so she can come down to about 8 turns per minute with full momentum. Greetings Peter Blodow
