Using Heat on a Stuck Pedal
Ok, I did a thorough search, and just to cover off all the bases:
I have a stuck pedal, Campy pedals, Campy cranks. I've tried penetrating oil, impact, yes I'm using a pedal wrench, yes I know that the left hand pedal is left hand threaded. Today, I tried a propane torch on it, and had a little success. I let it sit for a couple of minutes, heating, then I found I was able to turn the pedal about 1/2 a turn, before it stuck again. I tried heating it some more, but no luck. What I'm wondering is this. I know that the aluminium heats faster than the steel, but at some point, the steel is going to catch up, and of course, once you stop heating the ali will cool faster than the steel, presumably restoring or even increasing the bond. Is there a way to determine the optimum time to free a pedal?
