Question about my take apart axle system

@adamantiumpops

What about a notch on the axle and the body, with a pin there? Like a half-circle on the outside of the axle and a matching one on the inside of the body, then a small dowel popped into it. Could be a slight pain to align the second half in assembly, but no worse than tuning a TMBR.

So this idea is difficult because the axle is one piece?
