Start with a good penetrating oil. Let stand for three days with
reapplication of oil regularly;
Then bang solidly with a hammer a few times;
Then heat the connection till it glows a dim red;
Then put wrench to bolt;
Bolt will break at the most inopportune place while you are pushing towards a
jagged surface with your knuckles outward.
Drill out center of remaining bolt;
Apply easy out until you have totally stripped the inside of the bolt;
Repeat process with larger easy outs until the bolt is completely gone, and
the receiving threads are also destroyed;
Get a larger drill bit and drill out the hole to a larger size;
Rethread the new hole;
Attempt to insert the larger bolt (at this point you will notice that you
jumped threads with the rethreader)
Repeat.
Voila--works every time.
