After injecting resin into th molds (Gotta work fast, this stuff has a 2 minute working time!), immediately place in a pressure pot at about 80 psi (pressure pots' limit). This step gets " The liquid resin into all the nooks and crannies"! |

The 3m Flexi Bandage tape worked out well to hold the mold halves together. Rip off a length then tear strips off at desired width. 1/4", 1/8", no.problem. This replaced the rubber bands I forgot. Glad I did, the tape worked much better! Another "Fortunate Mistake". |

A sharp no.11 to the pattern. This is one way to do the parting. It's much quicker than making two separate halves with two mold castings. Ugly as sin but it does yield excellent results with an almost invisible part line. |
