I have a chance at getting an old lathe from work for a good price but it needs 3 phase power. Below is the tag on the machine:

I've read this article on Making Three Phase Machines Work in a Single Phase Shop

It sounds like I have 3 options for phase converters, a static converter being the lowest cost option. Problem with it is in cuts the power in 1/3 and needs to be sized properly for the motor it runs. Not sure if this would work for me or not.

Not sure on exact cost of the lathe but I'm figuring around $3-500. It's not a great machine but is good enough for making spacers and other odds and ends. It is manual (no CNC), the 3 jaw isn't true, the tool holder base has some stripped threads that make it hard to get it locked down rigid etc. There are some odds and ends tools that come with it (ball bearing tail stock, 4 jaw, etc and quite a few other things that I'll probably never use). Size is around 36" not sure on the throw. So given the cost of the machine and its condition I don't want to sink a ton of money into correcting the phase.


Looking for guidance from anyone who might have been through this before.
