First, order some urethane casting compound. [http://www.devcon.com/products/products.cfm?familyid=152 Devcon Flexane] is a good choice, or, a more generic, less-expensive product, such as [http://www.mcmaster.com/#8644k11/=3f24h0 part #8644K11 from McMaster Carr]. This can be used to repair seals, make molds to cast ceramics, etc. It comes in two parts; you mix the two together, and then pour them into your mold. They take 48 hours to cure, and there is no baking required. Because this compound only shrinks 0.0005" to 0.0014" per inch of thickness, there is no need to worry about making your molds oversized. | First, order some urethane casting compound.
