The point was to move the air, and that they do. Turned down to 12 volts would be a lot quieter, but when I found they didn't let the magic smoke out on 19 volts, I lost the urge, those expensive A3977's need all the cooling they can get.
> Thanks for the compliment. I started out with quality iron, it really > helped. Yes it does, but what really upsets me is that you got it for less than I could get it if I was carrying a bazooka! Such deals never ever show up out here in redneck country. I did see an old Bridgeport sitting out in the weather for several years out south of town, but it disappeared before I "got the virus". It may have been in such poor shape it was just 3k lbs of scrap iron too. I'll never know. Sigh... Side questions, 1, I assume that was your son, and 2, where did you get that toroid for the motor supply? That would allow me to tweak the voltages in my rigging because its so easy to add a few turns to the windings compared to the 30lb potted E frame boat anchor I use now. -- Cheers, Gene "There are four boxes to be used in defense of liberty: soap, ballot, jury, and ammo.
