Mine too is a J model... mine was made in 79... I wish I paid$75!I wanted one as soon as I figured out that mill would drill square holes! I was about 16. I have a J model paid 75 dollars in 1978!
I used a converter....it was only two hundred dollars.Is your mill 3 phase Clint or did you covert to single? Definitely a handy tool to have.

You can run it that way.Can you run it with a VFD off your single phase?
