Every time I encounter a rusted bolt that I know is gonna be a ***** to remove I bust out the O/A. Heating AROUND the bolt until its just about cherry and IMMEDIATELY start trying to remove the bolt when the heat is taken away. I also make sure before I heat it up, that the wrench or w/e is going to fit perfectly snug on the head of the bolt. If the bolt does brake or its a rusted stud like on a boiler header. I'll just go right to grinding it flat, drilling and tapping it. I <3 my tap and die set. Always use an oil too when drilling and tapping. When tapping, do one full turn and then back a half turn to break up the filings. When drilling, press down and drill slow. Just like a drill press.

You guys are coming up with some awesome suggestions that I will add to my toolbox. Thanks! Keep it up! Maybe we can write a book on the finer points and nuances of removing broken stuff without pulling your hair out.
Kimball-Midwest Penetrating Oil. Smells like cherries, works like nothing you've ever seen. I blew up the front end in my old mud racing truck once, in the process of taking that apart, I had to remove the spindles. The first one I had to ram with a forklift to remove. The second one got a little spray of the Kimball-Midwest stuff, it came off with a couple light taps from a 16 ounce hammer. The stuff is magic in a can. In this field, anything I've snapped off, I've just put another screw in right on top of it. I only do residential though.
Left handed drill bits are must, X2 on Snap on extraction products (been through many Snap on works and lasts) and X3 or 4 on the tranny fluid. the candle wax trick works, I also never done my self but a friend in the marine industry uses ''Mint'' on aluminum.

As for extractors, I have tried a lot of different ones. So far these are the best I have used. http://buy1.snapon.com/catalog/item....mp;dir=catalog
In automotive repair, and later in boiler and pump repairs, I have used the candle wax trick many times with success. It gets sucked into the threads like solder. Guys, if you heat the tapping instead of the bolt you will get better results. When you heat something with a hole in it the hole gets bigger. If you heat the bolt more than the tapped piece, it gets tighter until the temps equalize.

Gonna have to remember all of these for the next time!

For broken bolts that are not too rusted in I like to use a left twist drill bit to drill them out. Many times just the drilling force will be enough to back to broken portion out. Otherwise heat and patience normally work.
