Prop Dressing Errosion
One thing I could never figure out is the frequency of cleaning up the leading edge. Dressing removes material-even if only several thousands. If one would theoretically dress the prop after each sign of erosion or minute pitting, one would remove a finite amount of material equal to the depth of each imperfection removed. This would add up quickly. So then that brings up the question: How long can these minor erosion pits remain before needing to be addressed. Note that I am only talking about the erosion type roughness and not a noticeable singular rock ding which should be addressed immediately. My concern has been changing the original blade profile by dressing too often.
