Made up a small rotary phase converter for fun and games, and it actually works quite well! I used a WYE motor, as I couldn't find a delta one for cheap. Used a kickstart kit for start up, and added run caps to help tame the wild leg a bit. The little fan was just laying around so I put it in there to keep it all cool in the summer. We have it running a shear with a 3 HP motor.
