| Luckily on the last one with a good launch, I launched into sink. It would have been on the roof had it been in "Good" air. Name and phone number is going on next! |

| "Moist" just isn't an adequate description!! |

Pulled them out of the pot after about 30 min. still have to wait at least another 30 min. to demold. The waiting game. Tic Toc...Tic Toc. Don't remove too early, They will deform. |

Another must for proper castings. 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"! |

Ready to cast. I recieved this urethane resin from DD. Very thin withou too much shrinkage. I "Like" it. 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". |

Plunge cut a Zig-Zag pattern for the outer edges (for registering the mold halves) with a chisel point blade. 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. |
