Well, I have decided against eliminating the step pulleys.? It would be much more complicated than just replacing the motor and installing the VFD.? Then I will have full options available as to power.? With the VFD and three phase motor I will easily be able to overspeed the lathe.? Does anyone know what the physical speed limits of the lathe mechanism is?? At his point, I see no reason to ever do so.? Just wondering.

My concern is the plain bearings in the headstock. I don't run either my SB9A or my SB13 much above the listed top speed of either lathe.
