David Posted March 2, 2005 Report Share Posted March 2, 2005 Basically Ive got an old frame im building up but the first few threads on both sides seem to be a bit knackered. No matter what I try I cant get the bb in straight and it just cross-threads. I was wondering If anyone has any tips for getting it in? Apart from re-tapping and buying a threadless bb. I was thinking of re-chasing the threads with a chisel or something? Quote Link to comment Share on other sites More sharing options...
Tartridge Posted March 2, 2005 Report Share Posted March 2, 2005 You may be able to cut the first bits of the threads out (stanley knife) if its an alloy frame, but, best option is to head down your LBS and have them chased through (Y) Quote Link to comment Share on other sites More sharing options...

Brian Bleech Posted March 2, 2005 Report Share Posted March 2, 2005 When trying to get Tim's (dr evil's) cranks off and the first lot of threads were knackered on his cranks and we couldn't get the bb tool to screw in, so I put some sellotape on the inside of the crank over the knackered threads and the tool just kinda 'cut' new threads into the sellotape, until in caught the good threads and then worked fine you could try that. Although if you are building up a proper bike for riding you probably wanna get them chased, but if its just an hack or mess about bike you may not be wanting to spend too much money on it and may be worth a try!
