I built a rotary phase converter for under $20 using cast off parts that I scrounged: a 5 horse 3 phase motor for the converter, a 1/2 horse 110 motor to start the converter motor spinning, and then bought 2 pulleys and a belt to connect them.

I don't regret the things I've done. I only regret the things I didn't do.
