My first attempt with 3 phase
I don't think anybody has mentioned this in the thread...
Another thing to keep in mind. If you are using a 3 phase motor not
specifically designed for use with a VFD, slow speed running may cause
it to overheat. VFD rated motors are built with higher temperature
insulation on the windings because when the motor runs slowly, the fan
runs slowly.
I think that Bill N has suggested running a plain old fan pointed at the
motor in a prior thread but that seems a little Rube Goldberg to me.

Hey Rick,
Thanks for the info. Unfortunately(or fortunately) I am a
thousand or so miles from Columbus. I Live just outside Missoula
Montana. But I would like you to keep me posted on your progress. Do
you have any online pice of said lathe? Well thanks for getting back
to. I am going to do some more looking into the VFD's.
