Kendall:
I believe the claim is that residual stresses in the crank relax over
time, so older is better. It also may be that the thermal cycling increases
the rate of relaxation (Any metallurgists out there?).
I would hazard a guess that even a NOS crank has had plenty of time to
relax, thermal cycling or not. The newest crank you could get now would be 30
years old, so it is probably well relaxed. If not, give it a beer to drink and
it will relax. It always works for me.

I thought I'd heard before, (possibly from
you?) that a used crank was better than NOS because they were better if they
had been used for awhile.
Mine crank was already 0.010 under so yes, it is
definitely scrap.
