In order to make the NACA scoop, I needed to make a plug to mold the fiberglass around. I made this out of scrap 2x4s. It is covered with fiberglass resin (no cloth, just resin) to seal it. It has also been coated with several coats of wax. My friend Roger has promised to help me make the actual fiberglass part using vacuum molding. We'll see how it turns out!
