Still failing to see how that will make the prop stay on the shaft without a nut. Lapping is not done to lock the prop to the shaft. It is done to give more effective surface contact area, in order to increase the coefficient of static friction...... And to reduce any chance of wobble.
Ironically, proper lapping of a tapered fit will actual pop free easier with harmonics.
