After several attempts to get the nose portion of the aluminum skin to fit the compound curve of the stb wing, I decided to try mold a fiberglass part. Made plywood copies of #1 nose rib and root nose rib. Fastened into position on another piece of plywood. Used 2-part poly-urethane foam to construct the compound curve of the part & laid-up the skin with 4-oz. fiberglass cloth using West System 105 marine epoxy resin.
This worked well, but I'd have to make the mirror image form for the port wing. I decided to give the two part aluminum skinning process another try and was successful on the port wing. I now have one wing root nose in fiberglass (stb) and one in aluminum (port).
