I've solved a lot of stuck fastener problems just by using a propane
torch and a can of LPS 1. Heat, spray, heat, spray, repeat as
needed. Sometimes it takes more than just a few go-arounds to get
things loosened up. In this case, I'd be heating the hole area, not
the fastener. Doesn't have to be red heat, just enough to expand
things. Then there was the nazi superbolt in the VW shock mount,
drilled that one out until it shucked the flutes off the drill, then
spent three days with a mini-die grinder and a handful of pink
aluminum oxide points grinding it out to the hole threads and picked
the bits out with a dental pick. I've had the most success with left-
hand bits on wood screws. Rusted bolts usually will drill or will
break the drill bit, but don't move until they're cored out.

I hadn't thought of the die grinder solution. I may try that before
the chip-it-out exercise.

Thanks
