Hi Denis
It could be that the outer hub is riding on the key. If you fettle the key you should be able to pull the hub on the taper. The half shaft should have a bit of room at the pinion end. Try fitting the outer hub without the inner hub and check that it doesn’t bind with the axle end. If not then I think it is a new half shaft.
I have stopped lapping tapers and use a Loctite taperlock instead. After 80 odd years tapers are bound to be well worn! (Bitter experience of lapping a flywheel too much
.)
Also remember that the outer hub nut needs tightening very hard. I use a 30” breaker bar and all my meagre weight behind it.
I think a hardened washer behind the nut is OK if you are worried about the split pin.
Cheers
Howard
