Jim & Len:

You guys are getting me exited! Maybe in a couple of months, when the snows finally melt, I'll get my No 10 out again. I haven't had good luck with a Cirkut in the cold.

RE: drilling spring steel - as you know, that don't happen with a drill bit. Using a small dremel stone works. You can also heat the end couple of inches to take the temper out, then use a drill bit.

Go for it.
