[QUOTE="shortgrass, post: 725502, member: 24284"] 'Bout the only way to get true 3 phase, if you don't have power company supplied, is to use a rotory phase converter. They are, in simplist terms, a single phase motor driving a 3 phase generator. I wouldn't buy one for each machine. I'd buy a large enough one and feed a three phase panel and wire my machines from there. Flip's right about the "hard start". Lathes without a clutch, air compressors, 3ph welders all fall under that heading. That VFD from e-bay might look good, but, check e-bay for "rotory phase converters". Not much difference in price and it makes "the real thing". Electronic "variable speed" isn't a 'gotta' have' for gunsmithing tasks. Simple gear changes work just fine. [/QUOTE]
