You can cast very complex models in one-piece silicone rubber cut molds. In this video I set up a model with the proper sprue and vents to let the urethane resin flow into the mold while the air is vented out. Good technique results in a bubble-free castings with almost invisible parting lines! ——————————————————————————————————————————— Would you like to mold and cast something but have no idea how to start? Send pics of your project to me and maybe I’ll do it as a YouTube video. Here’s a .pdf with the info: ?dl=0
