frequently the 50 to 60 hz will involve a pully and belt change on any 
mechanical system that involves larger motors directly powered from the 
main supply.  Other than that most of what you have should be strapable 
for voltage and frequency.

On ebay, you might search for an Elgar converter, or pacific power 
systems (I think) of huntington beach, ca) both of which make larger 
variable frequency supplies.

I had an elgar in the 5kw range, and a pacific supply that was 3kw in 
the past and both were quite reliable with solid state outputs.  Both could
handle the power factors to run motors as well as the power supplies.

They will probably be cheaper than what I had if they are strapped to a 
fixed voltage and frequency as well.  My pacific system had a 43 to 1000 
hz variable oscillator, which allowed 400hz power.
