Wondering if anyone might have experience with building up worn automotive splines?
I have a few crown wheel shafts that have badly worn splines. The material is soft (sacrificial) and I'm hoping to turn the old splines down in a lathe, build up with weld, turn down to size and re-cut splines on a hobbing machine.
There seem to be a few firms doing this in the US and Russia but I haven't quite managed to find out exactly what filler rods they use. Main issue is finding something that is hard wearing and still easily machined with a HSS gear cutter. Also need to keep the workpiece temperature low enough to avoid affecting the heat treatment of the crown wheel. I know there are probably better ways of doing the job (e.g. welding new, heat treated spline section onto existing shaft) but I'm looking for a faster solution that will allow me to ensure concentricity when cutting the splines.
Pictures I found either seem to show a stainless rod (possibly not hard enough) and a bronze coloured filler that builds up the worn splines. Anyone got an idea as to what this could be?
Know this might be a tough one but got a few pieces I'm hoping to make good.
Thank you!
