I'll be lucky it its 500 revs doing a g76. And with this monster, probably rigid tapping is out of reach at more than 50 revs. I can make one of these frame 142 Century 3 phase 1 HP motors I bought yesterday jump half off the table doing a reverse from a 60 hz drive in about a second with this inverter, but thats still an overshoot that needs to be compensated for in the z value passed to a g33.1. And while I can reverse the motor, there will be all those squawling v-belts as they protest trying reverse a 40 lb chuck (and I can figure out how to lock that 2.125" thread from unscrewing itself off the nose of the spindle) ;-) Besides that, I have no intention of being in the same county with that big chuck doing even 3000 revs. Country boy dumb maybe, not stupid. You never did say which of these hall switches you were using in the bridgeport? Cheers, Gene Heskett -- "There are four boxes to be used in defense of liberty: soap, ballot, jury, and ammo.
