Anyone Heard of Youngs?

wolflore On a more serious note.
As it was bent slowly and smoothly - somewhat akin to the sort of bend you'd get from a pipe bender - you may well be ok taking her back the other way. Only as long as you get her up to a good temp - we're talking nigh on cherry here!. You need to anneal the metal and then then take it back the other way - then anneal it again. All in all though it would be easier to replace the piece that is bent ;-)

chris crash ok stop now, put the blow tourch and the hammer, and wood down.

1 when you heat steel not high enough to heat treat it you weaken it.

2 it has allredy been bent past its tinsel strength, and thefore weakened

3 it has been bent like that for a long time and due to steels memory you will have to bend it back way past its tinsel strength again, weakening it further.

take it to some one with the proper tools, removing and replaceing a seat stay is not that labor intensive, though it may be a bit ore difficult on a brazed frame, as i have only done welded ones
