Been an engineer since I was 17 (now 39, no really

I've just bought an old Easimill and need to change the motor to a single phase one, or run a 415v O/P inverter (expensive)
The motor is not a dual voltage one so the cheaper inverters are no good as they only output 220v 3 phase, also the shaft is quite long so an adapter will be needed or a special order motor sourced.
So how have other users got round this problem, what motors did you use?
Thanks
Steve
