What to Mold creature Hand from?
Hoping someone with experience in many different type of mold making materials could give me a better idea of what would suit this specific project needs best. Here is the purpose of this project and mold: Doing a test run for an animatronic hand. I've done the sculpture in Monster makers oil based clay, The goal is to have silicone skin that I can slip over the cable mechanisms and mechanical insides. I will only need to use the mold to create one to two skins (casts) and needs to be able to capture very high detail. Also I need to be able to put clay into the mold in areas that I need thicker and thinner for the "skin". pour in plaster to make a core mold, take the mold apart, remove the clay and float cast the final skin between the mold and the core mold (Hope I explained that clearly). I did some research and have watch most of the mold making lessons here and I'm not sure What would be my best option, I thought Hydrocal would be a good option but than I learned about Fiberglass molds and thought that might be better for detail, The main thing is I want to be able to capture all the details in the sculpture, the longevity and multi-use of the mold means nothing to me for this project. There may also be a better process out there I don't know about, so any advice is good.
Hope to hear your thoughts.
