This can be used for pretty much ANY frozen metal parts...on a bike, truck, horse trailer, whatever:
Forget the heat gun...you need a propane torch. When heating up the offending piece, make sure you only apply direct heat to ONE surface. I.E. - for bottom bracket, heat up the metal surrounding the bracket. At the same time, gently (or not so gently), tap on the bracket with a bronze drive. Tap some more and you should be able to break whattever bonds (grit, rust or both) are holding it, and wrench it out as normal.
This all is helped by soaking the damn thing in PB Blaster for like a week.
When you go to put in the new bottom bracket, make sure you use a very high-quality water-proof grease...this will make it easier to take the BB off next time. BBs get a LOT of abuse from road grime, mud, salt-water, stream water etc....that is why they're like a WITCH to get out !!!
"The reason death sticks so closely to life isn't biological necessity - it's envy. Life is so beautiful that death has fallen in love with it; a jealous, possesive love that grabs at what it can." by Yann Martel from Life of Pi
