Home shop power for a big machine

I was lusting over a big VMC that would never fit in my home shop and
got to wondering about power. The machine's data plate says 230 volts
3PH @ 80 AMP's, 18KVA. It has a 15 HP spindle.

I could use a rotary phase converter to generate the three phase but
don't have anywhere near 80 AMP's available. 18KVA/750 watts equals a
24 HP phase converter.

If you where using this machine in a hobby environment and not trying
to get production feeds and loads how small of a phase converter could
you get by with?
