bent aluminum hanger

I've got a bent aluminum it's not one of those replaceable ones (schwinn 564)...yes, I have access to one of those derailler bending-back tools...

does anyone have experience with heating aluminum to bend it? I was told that this might work

It really just depends on how bent it is and how many times it's been straightened before.

I've done minor aligning on many, many aluminum frames, both with and without replaceable hangers, and have yet to break one. I do keep in mind that aluminum only has so many fatigue cycles in it and always go slowly.

As for heating it...I don't see how you'd accomplish that in a way that it wouldn't defeat the heat-treating and soften the metal.

The first question to ask yourself is: "Can I ride it the way that it is?"

If your answer is "No" then you have nothing to lose.

I haven't realigned a huge number of dropouts but I've done a few including a couple that were seriously bent. My experience has also been good but YMMV.

Reheating a bike frame that was heat treated in the building process doesn't sound to me like a good thing to do.
