Have you seen how they do this with phosphor copper. I have been trying to find that info but not found anything online. Reason is I have a set of axles I'm rebuilding and I have to have the drilling etc. done on the shafts and I'm trying to evaluate which way to go.
Nice, how much of a flex in the shafts end to you think the nylon "can eat" I haven´t checked yet the length there and perhaps it´s long enough to allow some flex in the shafts end.
