I appreciate that axles for all sorts of cars have been welded forever. Yet all the good books emphasise the problems of welding higher carbon stressed steels. There is more to it than running layers of common mild steel bead around.
There seems considerable scope for removing the gears, boring and very tight pressing onto a new shaft, and welding the outer end. Dunno if anyone has had success with this. Perhaps it softens the gears too much, or the press fit relaxes.
It is curious that over stressed parts subsequently better resist fatigue, hence the advice. i understand the life of road springs is greatly increased by initial scragging. The endurance tests on the original test Comet appeared satisfactoy because of initial over stressing of the prototype.
