Two days ago, I was fitting my prop to the hub to turn the engine by hand (I do that from time to time for preservation, when I notoiced something very strange.
My KR2 has a fiberglass spinner. There used to have a plywood plate at the front end of the prop, after the crush plate whose function is to help hold the spinner in place nicely. It matches the inside of the spinner cone tightly. About 80 fligh hours ago, I replaced that plate with an aluminum one (2024 T4, 3mm thick). What I saw yesterday is that the plate has been "eaten" badly (looks like uneven grinding) on two opposed sides, exactly abeam the propeller blades cutouts. I then checked the spinner cone, and indeed, the fiberglass is eaten exactly at the same place. Would anybody have a convincing explanation for that? What must I do?
