For Sale: interesting, but tricky Bob Jackson

heres what hilary says about tapping (different thread)

Argos here in Bristol will ream a BB shell and fit a new sleeve which is threaded for £65 - the sleeve can be brazed or glued in if you do not wish to disturb the finish... This is the best solution for stripped BB threads. But slitting the BB edge, closingup and brazing does work if done carefully; its just rather messy... though a lot cheaper.
