Thanks, I guess good advice, I thought $3 was too good to be true. What I really want to do is reduce my lathe to about half speed using the lowest headstock gear of 60 RPM to get about 30 RPM for the occasional tricky screwcutting operation, as this would be very low load on the motor. For general turning I would be quite happy to just use the headstock gears and run the motor at full speed. I could of course add a smaller pulley to the motor. I may never have to use it. It was just a thought and at $3 it appeared attractive but if I risk burning out the motor I will have to give it up.
I could have ordered this lathe with a 3 phase motor, but I really don't want to go to 3 phase as I would have to get an electrician to bring the 3 phase to my shop.
Thanks again.
Bob.
