In my very small shop I have a lathe and drill press, both for 3 phase 220. My house is an older place, not wired for 220, but I do have a 30 amp 110 circuit to my shop. I use a little Baldor variable frequency drive. I mounted it to the wall and have an old three phase motor direction switch to route the output to which ever machine I want to use. The only caution is to not switch the output of the VFD while it is putting out power. For control, I built a small remote control box that is wired to the VFD with a small armored cable. The box has a switch for direction, stop, a control for speed, and a meter that shows speed 0 to 100% (100% is 90 cycles for a little extra speed, so 66% is normal speed). This has worked out very well so far.
