Gents,
Bit off topic I know but this ones got me a bit stumped
My boss is a very keen cyclist and in the process of stripping down one of his frames has got in a right two & eight!
The bit where the pedals/crank (?) go through has a fine thread in the steel frame which has two seperate alloy inserts which screw in one on either side. One of them unscrewed with no problem, the other won't shift at all.
I suspect the aluminium oxide has reacted with the steel and being such a fine thread has locked it solid.
Using the removal tools he has has only managed to completely knacker whats left At the moment he's hacksawing every 3/16" down to the crest of the thread of the frame hoping to be able to remove whats left in sections. Because of the carbon bits and thin steel my sugestion of a gas axe was turned down
Short of centering it on a big mill and boring out to the frame thread crests and picking out the remaining bits I can't think of anything else.
Has anyone got any other ideas?
Paul
