At that stage; I'd turn it as far as the tight spot and give it a few strikes with a hammer. sometimes you can ease it out bit at a time that way. Once I had to shift a seized in pedal shaft, after snapping a couple of spanners - I welded on the biggest nut I had a spanner for. Quenching the hot steel with penetrating oil did slightly more than just spraying it on cold. The same approach would probably work with a BB cup. It is extremely bad practice to hammer a pin spanner. Who said anything about hammering a pin spanner?!!! If you can't be bothered reading a post - don't bother answering it either. I might suggest "At that stage; I'd turn it as far as the tight spot and give it a few strikes with a hammer. sometimes you can ease it out bit at a time that way." sounds an awful lot like hammering on a pin spanner. Are you supposing we're discussing removing pedals from a crank? Sorry - I forgot you were that thick. I'll draw pictures next time. So you meant something other than what you wrote. Well that makes sense. Its so simple it just never occurred to me that anyone could **** it up - but somehow you always seem to manage. Then perhaps you can explain how you didn't say to hit it with a hammer after writing for everyone to see you suggest hitting the pin spanner with a hammer? Did you mean that unless you vocalize it, that it doesn't count? I didn't say hit the pin spanner with a hammer - you did. And I would have understood you better if you spoke in English instead of Benderthe.evilrobot doubletalk. Tell me who hits their paint job with a hammer? |
