I bought myself a nice old J head Bridgeport a while back and I need to get some power to it. I have single phase 220 in the shop but need three phase for the mill. Called the power Co and they said no problem we’ll be right out, no charge. Apparently in the 15 minutes it takes to drive from their office to my place the bill went up from $0 to $1600.

So I need to build a phase converter but I am not by any stretch an electrician. I have a 1hp AC motor for the pony and have two brand new 3 phase motors to use as the generator. My dilemma is that the motor on the mill is a 1hp and the two I have for generators are a 7.5 and a 10hp. Will those be too big? About the second to last thing I want to do is burn up the motor on my mill.

Any help is appreciated, I need to get this thing up and running and making money.
