I am working on a project and using 1 1/4" stainless steel exhaust tubing with .065 wall thickness and need to weld straight tubing to a cut off bend. Problem is the bends OD is distorted probably because the manufactures mandrel is getting worn and allowing the tube to distort. Does anyone know if and where you could get a tube expander that will do 7/8" to 1 1/4"? I have bought cheaper ones but they don't work so I am looking for something that would expand the tube to it's straight length and only maybe a 1/2" of tube since it is in the bend area and it is 2" CLR.
Thanks, Ed
Yes I have made a tapper and been hammer it in the end but I haven't been able to quite get it to the straight OD.
