Three Phase Power in your Single Phase Garage for Lathe, Mill

This is always a problem with small garage shop owners. How do you get a good source of AFFORDABLE three phase power in your garage to power your lathe or milling machine? The traditional way is to buy a static phase converter. The static phase converters work ok but they leave you with only 2/3 of your original horsepower rating and they make that clicking noise when you shut your machine off. I came up with a better solution. I bought a new Variable Frequency Drive controller off of eBay for $140. It was a Taiwanese unit but it work great. The VFD does two things for you. It converts your single phase 220vac power to 220 Three Phase without the HP loss and it gives you digital speed control. This was awesome for me. It also made speeds changes a breeze. The key to all of this is that I had a non-used 220 circuit for an electric dryer on my electrical panel in the garage.
