Hello, I have an insanely seized bottom bracket cup on my bike. I took it to my LBS, they soaked it in some PB penetrating oil, used a special tool, and still couldn't get it out. They told me I should go to a local frame builder and have them torch the bottom bracket shell so it expands and I can get the cup out. The only problem is the NAHBS is around the corner so everyone is super busy for the next few weeks.
The paint is old and messed up, so I don't care about that. Its an old lugged steel frame and I think they used brass to braze it together... I was thinking about getting a butane torch from the hardware store and just do it myself. I just don't have any experience at all with this stuff.
I have a couple of questions:
A) Is this a bad idea? Should I just be patient and wait a couple of weeks?
B) If I do end up doing it, what equipment should I have besides the torch, wrench, and gloves?
C) Can you give me some tips for doing it myself?
