Singlespeed & Fixed Gear "I still feel that variable gears are only for people over forty-five. Isn't it better to triumph by the strength of your muscles than by the artifice of a derailer? We are getting soft...As for me, give me a fixed gear!"-- Henri Desgrange (31 January 1865 - 16 August 1940)

It's bent. By about 4 millimetres. It's made of steel. Someone stop me from bending it back with an adjustable crescent wrench. I'll need a good reason not to, because the noise is driving me nuts.

I wouldn't have a problem with doing that, because its steel. I might even do it with alu. But it will never be straight/round. That might anger you.
Bend it back with the cresent wrench, check for flatness on a flat table,counter,etc. You could make it more flat via a BFH. (big _ucking hammer)

You'll probably never get it perfect again, but if you take lots of time, make tiny little changes, and check your work often and with a good reference*, you should be able to get really close.

Heck, give it a shot. What have you lost if you can't fix it? Even the time spent can be chalked up to learning.

*Carbon paper over a marble slab (or tile) is a great reference, if you happen to have one lying about. But then I suppose you could be practical and use a countertop or a straightedge. Your choice.

Using a 'pair' of cresent wrenchs' is a common method of truing a chain ring regardless of what it is made out of.

Or just stick it in a nice big vice and do gentle, considerate, loving violence to it that way. Whatever works for you. There's no nice way to do this.

Yeah, a vice would probably be a better way to do it. The larger gripping surface would make it a lot easier to avoid little zigzag bends all over the place. Just be sure to use some sort of pad on the jaws, or you'll wind up with pockmarks all over your ring.

(And what's all this about "gentle, considerate, loving violence"? Um... )

if you have a nice smooth area (such as a concrete garage floor) and a car or truck or something, try running it over, no not a burn out on it, but just slowly drive over it, sometimes if the metal isn't bent to badly, you can sort of press it back into place, not a garenteed fix, but it sure is lazzzzzy, and that's always good. ooooh yeah, what a *****in run on sentance!
