Gene, We built a rotary phase converter from a salvage 10hp 3 phase motor and a few bits. If you have a motor repair shop nearby sometimes they have used motors with damaged shafts and the like that you can pick up for $25 - $75.... I missed part of the chat on this but if it is 3hp or less I would use an Automation Direct GS-2 VFD to convert my single phase to 3 phase. I have one on my mill and it is a lot quieter than an old rotary phase converter.
If you decide to go with the DIY rotary I can share with you everything we did to make a self starting rotary phase converter.
