Check out the METAL WEB NEWS at:
http://tbr.state.tn.us/~wgray/index.html

There is some info on building a 3 phase converter. I can also FAX you some 
other articles on this if you want.

This does seem to work   I had an electrician friend of mine relate a story of
a convent which lost 1 phase.  All worked well until the frugal sisters
turned off the heating sytem with it's 3 PHASE motors for the night.  After
that some lites went out because the motors were no longer 
making the missing phase.
