I'm tryin to get this thing recapped and I got one of the set screws
on the xtal switch all buggered up. It's made out of titanium or
kryptonite cause I been after it with a drill for about 2 days and I
barely dented it.

Two stops at Ace hardware on my way home for their best drills and I'm
stymied. I started with a 1/16 white, then the black hardened, and now
the cobalt. The cobalt is probaby the best, but they'res gotta be a
better solution.

So what do kind of a bit am I looking for?

Next screw I think I'll try some WD and a little heat.

Bob,
If you're referring to set screws in the knobs, shaft-couplings, etc.,
they are, in fact, hardened steel. Drilling them out can be a futile
effort. A combination of penetrating solution and the proper size easy
out should do it. I will tell you , though, on occasion I have had to
use the Dremel tool with a cuttoff disk and dismember the offending
coupler, etc. as nothing worked. The worst case was a stuck main tuning
knob on a BC-348 that simply had to be removed. Now, that was a
job.........!
