Following that thought Andy, would there be a way to determine which direction (as in axis to effect if it wasn't Z) by that method? My experience with edm has all been Z driven as I was removing broken screws from blind holes, which because of the lack of dielectric electrolyte circulation in a blind hole means you eventually short and have to back all the way out, vacuum out as much as you can, refill the hole with k2, and go burn another 10 or 15 thou. Pain in the butt. But I did get it done. Eventually. Did I mention it was slow? Very slow. 2 broken 6-32 screws were about 3 days to remove. But later when I needed some holes in the web of a table saw blade, I rigged 2x the voltage, to about 80 and 5x the cap (2uf to 10uf), and using a piece of brass tubeing of the correct OD, that worked much better, about 10 minutes per hole, but I did have to wear my Silencio Magnum ear muffs (30db loss) as I expect it could be heard several blocks away. Even with the muffs on, I'd guess my ears were getting 130db. There is loud, there is damned loud, and there is "Oh my Gawd is that painfull" loud even with the muffs on. That was definitely in the latter category. Cheers, Gene Heskett -- "There are four boxes to be used in defense of liberty: soap, ballot, jury, and ammo.
