Well, Ben is right again..."I'm cooked". I'll spare everyone the details,
but I have broken off a bolt extractor inside the drilled out portion of the
stuck bolt. Funny thing, I later read on some other forum that you "never"
use an extractor on a rusty/seized bolt, only on one that broke for some
other reason. I tried drilling with cobalt bits, but progress is negligible.
Oh well, the kids enjoy playing in it  :)
