Here you can see I have cut and riveted the spinner backing plates and now in the process of shaping the cardboard cutout as a template for trimming the fiberglass spinner.I need to explain the cardboard template you see in the next couple of pictures. I had gotten a little excited about putting the prop on, so much that I went to the trouble of torquing the bolts down and getting it firmly attached. So much so that I didn't want to take it back apart to assemble the spinner. So I decided to tackle it on the airplane.Now I don't recommend that anyone do it that way as I had to spend additional working around the blades to make sure they weren't scratched. I was able to do it, and it turned out rather nice as you'll see in the next post.This cardboard was drawn to allow me to evenly space the nut plates (maybe I'm too anal, but didn't know any other way to do it).
