thanks for looking at it well it could work abit better on very big 2.400 size forming a blank valve seats . i know how to run it the way it is .so it works really good all in all just looking for a weee bit more power .yes i was thinking tq from the pulleys stepping it down would balance out the lost of power from slowing the motor down with the frequeny drive .there no way you can stall it on small stuff. the drive is not at 115 .it could be 220 or 3 phase . i can look in to this i did not wire the power cord .i may go up on the front pully size .if i could get just a wee bit more pulley up there but not sure it would help much. i do not have alot of money in the motor and drive it was new old stock a shop had sitting a round. i think $400.00 the guy installed it for to .i not bitching about that .i could have him come back over and see if he would look at it.i just was thinking if it was a trim can or a dip switch i could turn it up my self . hard to say this could be a monster never had any thing to match it to or a pig but it works good i just have to watch stalling the 3 d cutter when it stalls they some times chip making junk out of a 50.00 cutter ...THANKS
