Bending a 4130 chromoly frame with heat question
I have a 24" wheeled jump frame that is 4130 chromoly, my plan is to modify it some what to fit a standard 135mm mountain bike rear hub in because as it stands it has a BMX width of 110mm. I have decided the best way to do this is to bend out the rear triangles at the point that they have been shaped for the tyre clearance as I believe this is the best way to keep the frames strength.
My question is, will it be ok to heat the tubing to red hot at the place I want to bend it?
Will the tubing loose much strength?
Will I need to quench it or just allow it a slow cool down?
Any other suggestions?
Thank you in advance
