inquiring minds want to know...
Lapping is typically a machining process to lap or make cuts on high spots of a surface with a cutting lathe. Lapping has become a common term for reducing a high spot in most all applications. Lapping a round (drive) shaft just machines (or laps) it down to specs within tolerance reducing a sticking point where a close fit is desired. Even sand paper and a whisk on a high spot is often called lapping.

I would not worry about a prop / shaft fit unless it were to be a b!tch to fit for some reason or the TIR shows a high spot to prevent a good fit. .
