Holy spring steel can also be made with a punch and die setup as per "Leaf Springs Design and Construction" by Frank Kerfoot in Live Steam March/April 2001. Electronic Discharge Machining (EDM) would do the trick for those with access to the equipment. And if none of these work, I'm reasonably sure the stubborn steel will be blessed enough to become holy. ;-] Charles > Spring steel can usually (noticed I said USUALLY) be drilled by running > the > drill very slowly, using plenty of thread cutting oil and keeping a steady > and relentless pressure against the drill bit.
