robbor Posted September 24, 2016 Report Share Posted September 24, 2016 The best way is to use heat vulcanized silicone for a spin cast machine or jewelry mold. The best part is no warming or feat dissipation. I can shoot lead the a wire size canal and fill a small ball head or ice fly. U have to heat it to cure it 1 Quote Link to comment Share on other sites More sharing options...

School Master Posted September 28, 2016 Report Share Posted September 28, 2016 Regular RTV will work for a prototype mold. I make a master out of clay or wood etc. Then I will glue it down to a board and build a box around it. Pour silicone over the entire thing and use a xacto to cut it out. I say it works for a proto because it will not last long at all. It's good enough to get a couple proto lead heads out for testing. If it works then I will take the time and make a 2 cavity mold out of something that will take the heat. I'm actually working on one right now. I will throw up some pictures soon to describe the process a bit better. Quote Link to comment Share on other sites More sharing options...
