 I am making some new molds for the Cosma Ray. Some of my original molds have broken from harsh flexing to remove parts and making parts with unwanted seams on them. Also all the existing molds were made too big for a couple of pots that I have so most all will be made small enough to fit all three pots. This will speed up the time it takes to make a kit. These original molds were being put in my bake oven for preheating. That caused them to become somewhat dry and brittle. Jeff the Time Machine Resin guy told me this is a waste of time. Curing resin will reach a temperature of 140 degrees.  Here are a couple of parts that are about the same height. How tall a part stands is something you will want to consider when you are doing a full kit compared to just a small group of parts. Engine halves may go with another group while the rest of the engine parts are not as tall. If you were doing an engine then the block halves would just go in one of the molds. Just some thoughts on conserving silicone use. Since the parts in the kit do not have numbers I will simply call this mold Cosma Ray 1. If the parts had an assigned number I would have taken the time to take my number stamps and mark the number in the clay the part is positioned in. |

   Here are some parts that are ready for the mold process. I poured a small amount on some parts and let cure before pouring a large amount over them to help insure they do not float off of their posts and become lost in the silicone mass. Originally there were about 5 pages of the Cosma Ray molds being created. They were hidden in the PARTS WANTED SECTION under the topic Mustang wheels. The pages have somehow disappeared from this forum. Admin does not know what happened to them. I may have started this project in 2008. In search of a way to make parts that are nicer and with more accuracy I came up with the idea of "claying up" the parts on a pyramid shape of clay. The idea worked very well. |

 I poured a small amount of silicone over some of these parts to insure they don't float away when i pour in a big batch. Some of the parts came out when I removed the clay. When this happens I spray in some mold release and then press the part back in it's spot. Sometimes it is not easy to do. i counted all of the parts in each mold. There are 130 parts to each kit. A hundred bucks for two kits is TOO MUCH?? I have been told that. |

Anyone that has told you that
1) Hasn't seen the prices of Cosma Rays already built & missing pieces.
2) Hasn't seen the prices of resin kits.

Thank you. I do as good as I can with it and keep my ego in check.
I did notice something about my original molds that made me unhappy! I made a body so that I could remove the Barris badge from it and make a new mold. I just happen to try to put the original kit hood in the resin body and it was too big. (the hood) HUH?? Yes, I'm not certain what is going on though those molds were put in my bake oven when I first started out from listening to those darn silicone vendors. My resin hood mold just so happens to be MIA in my room so I can't try a resin copy to see if the same problem exists. Nobody has complained of a fit issue but not many have been sold. So now I'm going to make a new body, hood and bubble top mold. Having a beak nose body would be nice too, I just don't know how to master one. (HINT, HINT)
