Hello nightowl - again,
After I submitted the previous post, it dawned on me that your motor is almost certainly a single phase motor (dah).
VFDs only work on 3 phase motors.
So all that rant about VFDs is only of academic interest to you. Guess I been spending too much time in the 3 phase world lately.
Anyways, its probably not cost effective to change out your motor to 3 phase just so you can use a VFD.
Another member has published an article on using a industrial duty sewing machine DC motor on smaller lathes.

Take a look and see if this might be a cost-effective path for you to get to variable speed.
Sorry for the confusion,
Terry S.
