I just got a Sale Notice email from Penn State, and one of the items is a variable speed conversion for the Jet mini (and other small lathes).
It looks interesting: http://www.pennstateind.com/store/e-10300.html
but I wonder how well it'd work. I also wonder the ite 680 rpm they show as the lowest speed is the lathe speed, or the motor speed. If it's motor speed, then with the OEM pulleys, it ought to let the lathe get down to about 175 ~ 200 rpm - much slower than 'stock.'
So, has anybody tried it? How well does it work. Shoulf I spend my pennies?
