used to do lots of flame bending ect in my muffler shop .never quenched as if caused problems .if i had a driveshaft or fork leg to straighten id put it on the bench heat the opposite side to the bend then use either the press or clamp to bring it back an let it cool naturally .with the flame unless you get exactly the correct spot an area then quench it will pull at diff angles ect
anuther way we would have our dies and put the shaft tube or bar[outboard shafts n inboard boat shafts]in a jig and bring back to straight then heat the whole thing but never get it hot enuff to discolour the hard chrome[on forks]or tarnish the stainless [boat shafts] then once it was all even roughly with the torches we would lwt cool again by itself .if it was still out a tad normally do as vinny says an give it a yweek in the press .
