Actually, it's parts 1 and 2 that are the problem. I am currently
stripping two old bikes back to frame and forks and I'm too crankful to
the tune of three.
Bike 1. An old hybrid partly cannibalised for the recumbent. I took the
chain ring crank off but the other one has a stripped thread on the crank.
Thus I can't use a crank extractor to remove it. One tip in a maintenance
book was to clamp the frame on its side with the crank on the underside.
Then, using a hammper and a blunt cold steel chisel, hit the eff out of it
from above. Apparently restricting the blows to close to the centre and
rotating it. This seems like it might take a lifetime.
Bike 2. The old Peugeot road bike I found. On this one the plastic caps
covering the crank bolts have been smashed. Unfortunately, these caps are
the screw in type rather than the pop in ones. This means the threads are
inaccessible and there isn'y enough room to get a socket in to remove the
bolt. I dis think about melting out the plastic but I'm not sure how
effective that would be.
Any tips?
