Take it to someone who actually knows what they're doing.

How goes the sawing and filing of that hanger that you've made useless?

And how exactly does one manage to bend a dropout?

Geared to widening rear drop outs for wider, newer wheels, but complete enough for repairing bended dropouts. If going to fixed / single speed, you may need to narrow the dropouts.

yeah, thanks, I know about that process, and I have read the article before .....thanks for refreshing my mind...

Its a beacon frame that I purchased from a bike garage sale, and the left drop is slightly bent outwards, not a deep bend, but more like a push out.

If it's a minor bend, the Park FFG2 or equivalent will make quick work of it. If you are a DIY mechanic, I imagine that some of the community bike shops will have a set lying about. If you're very DIY, you can see how a vice is functionally a similar solution minus the alignment.

LBS Oscar Wasttyn (sp?) on Fullerton between Western and California has a frame bending machine that will do the job right for not much money.

Had a similar, though more critical issue with my 1987 Specialized CroMo frame:

After gettimg runover by a Toyota Tundra this past Summer, my Bike faired much worse than I did; ending up with a severely bent derailleur-hanger (not the replaceable aluminum type, but the kind that's an integrated extension of the dropout itself).

I brought it to one Shop, but for liability reasons, they didn't want to touch it; fearing that they might irreplably stress the part.

Ultimately, I found UV Metal Arts in an Industrial Park in Bridgeport. Primarily a powder-coating operation, UV is also quite adept at frame repairs; which in this case was accomplished with a minimum of hand-wringing and expense.

Saved me from having to turn my hybridized vintage 18-speed Rockhopper into a Fixie!
