Help with VFD conversions - Leblond lathe 15x30 with 3HP & Bridgeport 1970's with 1hp

Hi Chris, I bought a Temco RPC for my lathe which I think is about 3 hp.; not certain because there's no tag on the motor. Here's their URL: http://www.temcoindustrialpower.com/ They have a knowledgeable sales staff & they'll probably advise you to buy a bigger unit than you'd expect due to the starting inertia. I don't have any details handy because the unit's in the shop & I'm in the house. You might try to find a used one that's at least 7 hp or 20A output. I mounted my RPC on Temco shock mounts & wooden 2x4s which are anchored to the shop floor & haven't had any trouble with it. I think I read that their units have a life expectancy of 100K hours if you use shock mounts.
