Brief Description:  Initial fiberglass work on nose profile

Started working with the fiberglass cloth and resin/hardener. I have nover worked with this material before, so I wasn't real confident. I started by pre-cutting the cloth to fill the gaps left by the sections on the nose I removed. I taped some cardboard on the inside to help protect the engine and provide some minimal backing. I had no idea how much resin/hardener I needed, so I mixed up about 7.5 oz, which is 1/4 of the can of resin. With a brush, I coated the exposed fiberglass and laid on the 1st layer of cloth pieces and applied the resin. I got the 2nd layer of cloth applied, but didn't get it all coated before the remaining mixture in the measuring cup turned into a sticky gelatenous lump. Lesson learned. I mixed up a smaller amount and finished coating the cloth.

Two hours later I trimmed the excess cloth and sanded to feather the edges. There is still not enough rigidity in the layers covering the large opening. It doesn't need to be full strength, but I want enough so that when I cut it apart, it will hold its shape enough to reinforce from the inside. I also added cardboard around the prop extension and taped to the new surface. That should make it easier to add additional layers. I plan to make the final hole slightly larger than the spinner backplate, but for now this gives me a matched surface to work with. Mixed up the resin and added 2 more layers of cloth.

A couple of hours later, I again trimmed the excess cloth, but I think it needs a bit more time before I feather the edges. Ugly brown aside, I think this is going to come out ok. The covered gaps are significantly more stiff now than after the first 2 layers.
