Guys I need to make myself another shaft for my QCGB,I may be able use it and just turn the OD down then install bushing to fit.But I may just try and make another shaft just to see if I can do it.The shaft has couple different OD's and on the end I will have to try and cut a 5/16 thread.I don't know what kind of material that I should be looking for that has a little strength and to be able to turn the OD down and cut thread on the end.What kind of material should I be looking for?
