That thought is a last resort, mainly due to a profound lack of suitable transformers after building 2 machines with kilowatt+ iron powered dc spindles, my junk box is severely depleted. Also the iron tends to have lots more ohmic power loses. There do not appear to be a surplus of big iron for sale any more, not like there was half a decade back. The choices are pretty limited on fleabay tonight just one page. I found one, only one, that would do for either motor, but he only had one. Std e-core. If he had 2 of them, I'd have bought them. $40. And one for $15 that could have been cobbled up but it was on your side of the pond so the shipping would have made it north of a $50 bill. MPJA, would have needed too many to get the amps and volts. I have some toroids I'd have to hook up and see what they are, but I doubt the wattage is there. I might investigate that tommorrow. Thanks Andy. Cheers, Gene Heskett -- "There are four boxes to be used in defense of liberty: soap, ballot, jury, and ammo.
