The tail is prepared for molding. A wall is built to separate it into halves. The first layer of brush-on silicone is applied to the tail. It is too big to go in the pressure chamber, so a different type of mold is built for it – one that will have the resin roto-cast inside of it instead of pressure cast. This means that instead of using pressure to eliminate air bubbles, I will pour a small amount of resin into this completed mold and then slosh it around inside the mold until it sets up, capturing all the detail inside the mold. Then the hollow tail will have a hole drilled in it and be filled completely with resin the rest of the way.
