240 v. i know enough about electronics to follow a schematic but not enough to know what i am looking for. i tried google but got lost in the maze. if anyone could point me in the right direction i would be most thankfull. thanks in advance sarex"sarex"
** You must find out what that motor is first.If YOU cannot tell by inspection you are in no position to make any sort of drive unit for it.
Here are some commercial "variable frequency drives" that suit small single and three phase motors.

240V sounde like single phase a three phase motor would be marked for 415V and have a 5-pin plug.
if that lathe is driven by an inducion motor (large, quiet, most lathes are) you're looking for a variable frequency drive, but may should also check withe the maker of the motor, there's some issues related to running single phase induction motors under speed...
