two of the LBS's here about have refused to charge me for removing bb's in the last six months. In both cases I left picture of the queen, sort of sepia tint, on the counter for em to get some coffees in.

I had the same issue recently, but on a family members bike with an old fashioned cup & cone BB. The solution was, of course, a 6 foot extension pole and a blow torch.

If the tool is slipping off, you can use a G clamp to hold it on - Just ensure the other side of the G clamp is on the BB spindle - NOT the frame! Replace the vice I have clamped on to the adjustable cup in this picture with your BB tool!

That's a darned good idea!

Find a new LBS :whistle:
Took mine in about 5pm Monday. Had a phone call saying it was ready for collection about 11am Tuesday. Cost me a tenner (including fitting a new BB - that I gave to them).
Agree totally.
I had an issue with a bottom bracket I'd neglected since 1997 - never touched it. Was contemplating the bike (actually a decent one) being history after trying everything, including help from a far stronger neighbour and a big lever.
Bike shop got it out for a very reasonable price.

If you are aywhere near SE London I can recommend a place.

just googled and this thread popped up :whistle: guess who has a seized on bottom bracket and is not at work where he could get his hands on some plus gas and a 32mm socket :cry:. Hoping that the Mrs is planning a wee trip over to see the Mother in law as I could be making a detour :biggrin:

Yep I had tried that trick, at least it stopped the skint knuckles but that baby was not for turning! Even after i got it loosened off , I still had bother getting it unscrewed. It is now back in with grease awaiting replacement.

I had the same problem with an old steel frame - the BB was so messed up and could not come off. Some of the teeth wore off on the BB. So my mate and I thought it's already well ruined so why not put the shell on top of the oven flame...4 minutes later after heating the BB shell of the frame we (with gloves on whilst the frame was piping hot) and gave it another go with the tool and it came off really easily after a few pushes with the extractor tool.

Put in a new BB and now the bike is a fully functional pub beater!

I can vouch for Yellow Tim's method of filing and cutting the BB away. After chewing up the grooves on the BB, drilling holes for a bar through, penetrating oil and heating with boiling water all failed, my LBS suggested sending it to a specialist which would have cost about £100. I used a small round file (£12 for set of 3 from hardware shop) and hacksawed to the frame in just one position. Centre-punch and hammer started it collapsing and I could then remove it by hand. Thanks Yellow Tim.
