Default Lowering Lathe Speeds With A Rheostadt. OK idea? Bad idea?

Was watching a Del Stubbs bowl turning DVD the other night he showed
how on a general with reeves speed control he rigged a foot pedal with
pullies to work as a clutch on a hinged mount motor.

I had an earlier thread asking about a Jet wood lathe, and one of the
things that people get concerned about is that some lathes do not have
a slow speed that is as slow as they would like it. Turners doing
outboard stuff seem to prefer to be able to get down to speeds in the
300's.

The lathe I'm looking at has a bottom speed of about 550.

Question: If I put a variable resistor in line with the motor to cut
the voltage when I need a low speed, would that do the trick or would
that be bad for the motor?



IIRC you have the 1236? The one with a lever with about 6 detent stops? If
so, you can pull the lever out on the lowest speed and push the lever down
farther. You just have to tie a piece of rope around the lever to hold it
in that position. I can get mine to go pretty slow in that position
