Once the machining is done, there not much you can do aside from lapping it. The main thing is trying to get maximum contact on the prop barrel, and some props are not machined the best, both in taper angle or surface finish. I've had to bypass props that the barrel was too wavy to get sufficient surface area and the barrel diameter was already bored to near max diameter
