I have put together several RPCs, I have long ago stopped using the cap start method. All the RPCs I do are pony start, and though I takes a few seconds to spin the motor up to speed, its more reliable than the offshore caps they sell here.
Allso have done them with tranformers to accomadate different machine voltages.
Pony start is simple, and I also never bother with trying to balance the legs. Providing the motor is at least 2 times the HP needed, its not ness. I will dig up a few pics if there is interest.
