Mike,
Astron makes a series of heavy duty power supplies for amatuer radio use up to about 70 amps. You do not want a switch mode power supply since the start load on drills or chalupas will kill the feedback and shut down the supply. If you have multi motor drive with any kind of friction in the drive train than you can expect easy spikes to over fifty amps at start up or direction change.
