8/19/13

Right now I have a hatch mounted to a board. The board is covered with Mylar and is acting as a flat place to lay glass around the hatch to that the mold has a flange. This is a positive... known as a plug. The surface has to be completely flawless but it only has to have enough strength to last long enough for me to make a mold off of it. To make the mold, I have everything waxed and sprayed with PVA. PVA is a sprayable film that will keep the mold from sticking to the plug. Then, I'll brush on tooling gel coat, back that with 1.5oz chopped strand mat, 1708 fiberglass mat, and resin. This will form a mold. I should be able to lift the mold off of the plug. The mold will be a negative of the final part. I'll talk about that when I get there. Right now I have 2 coats of PVA on my plug so the next step is gel coat and fiberglass.
