I recently converted a nice late-70s Colnago frame and I'm using what I believe to be the frame's original Campag BB. My chainline isn't quite as straight as I'd like it to be and I figured I could fix this by swapping the bottom bracket out for something slightly narrower.
Unfortunately, the Campag BB seems to be fused to the frame. It's probably been there for the last 30 years, collecting moisture that's made its way down the seat tube. I've tried everything I can think of, soaked it in WD40 and the like, tried to "shock" it off with a hammer. It simply won't shift and I'm concerned that when it does, it'll take the thread on the frame with it!
I've read that it's possible to remove a very stubborn BB by heating it with a blow torch, although of course you will destroy the BB and probably the paint around the casing in the process.
Does anyone have any other ideas that won't end up with me having to re-spray my frame?
Cheers,
Rob
