| De-molding went well but is the worst part so far. I just did the first pour, and advice is to go FAST. I mixed the two, stirred for about 10 seconds, and poured into the mold. I looked at the cup, thought crap - I mixed too much, and pow! It went from clear liquid to white and near solid. Yikes! Also keep in mind that the mixture gets HOT. |

I poured 2 tonight. The first is great and probably usable as is. The problem is that a couple small pieces of the mold broke off (safety detent hole, pivot pin detent hole) so future pieces won't be usable right out of the gate.
I had made way too much plastic the first time and cut it back on the second. Of course I made too little and the second piece doesn't have a trigger guard. I'm super happy though and plan on making a new mold so I can cut it better. http://photobucket.com/user/mp43sniper/media/2016-12-02%2022.20.13_zpszj5b9pmv.jpg.html |

Drilling a few holes is not a big deal to me compared to screwing up a mold trying to include pins for simple things.
I will, however, order the replacement parts for the AR15mold system. I think it'll make the mag catch area MUCH easier to do. Mine tore in a couple places so I have to clean up each casting. |

I think I need to make a new mold and cut the bottom of the mag well differently. Anyone have any advice? To minimize flashing in the mag well itself, I've taken to cutting the mold along the side of the mag well lip and then trying to slice the center plug deeper inside the mag well, so that the seam flashing there is deep enough into the mag well to sand out easily against the flats of the sides rather than in the complex interior lip. |

Awesome, thank you. |

My small pieces (mag release cavity and 2 small parts of the mag catch area that I accidentally separated from the left side) aren't holding up well. They are the most abused parts since they are pushed and dug out of the plastic after each cast.
I decided that I needed a new mold but didn't want to guess again at where to cut. Last night I made the left side pattern to cast the left side mold from. This will be a combination of Boris' design and the AR15MOLD. It will have a separate mag well core to hopefully make demolding easier. I'm excited about getting home and pouring the rubber into this pattern. http://s252.photobucket.com/user/mp43sniper/media/Left%20side%20mold_zpsp4i4csgk.jpg.html?filters[user]=61522316&filters[recent]=1&sort=1&o=0 |

The holidays have kept me from posting updates. So far I've made a bunch of castings. Most would be usable but have at least one bubble somewhere.
I got creative yesterday and made another mold. Now I can make fruity ghost AR-9's that take Glock mags. http://s252.photobucket.com/user/mp43sniper/media/2016-12-29%2000.41.02_zpseiotfj21.jpg.html?filters[user]=61522316&filters[recent]=1&sort=1&o=0 |

Man, 2 months later and no new posts? I ran out of chemicals and just recently got another batch (my excuse for not revisiting the project). I thought there would be at least a few comments since I was here! What is everyone up to? I'm trudging through my honey do and projects list right now....one down another 25 to go  . Fruity Ghost V2.1 is #25
