Looks like you have done a fine job.
also appears you have alot less wiring with the new 3 phase stuff, you gotta like that, ;)

Your going to like having the vari-speed with the VFD

One issue I ran in to with this upgrade was the placement of the power wiring box on the motor. It sits on the bottom side of the motor when in place on the lathe and I had to make a flat cover to get it to fit...If I had it to do over, I would have payed more attention to where the wiring box is located when I was motor shopping.
 
Jonathank. I know this is a very old thread but i am curious how the upgrade has worked out over the years?

Thanks, Joe
