No time like when you need it. Another thought, dependent on how well it has galled & self welded, would be to get out the mig, and weld a handle to it. Between the heat of the welding, and a little PB Blaster, it might come off that way if you can adequately hold the screw, like putting the drive components back onto the splined end? If it works, a heck of a lot faster than the edm which I can imagine taking several very noisy hours, or would using my supply and capacitor. 80 volts, 10 u-f= a god awful, make yur ears ring racket. also faster than the usual 30 volt .5 u-f setup. ;-) Cheers, Gene -- "There are four boxes to be used in defense of liberty: soap, ballot, jury, and ammo.
