Our rubber props are actually made from C-1520 which is actually a very tough semi-rigid liquid plastic. It gives the prop guns a nice heft with a very slight give in the barrel. Our 13″ hammer has a fair amount of give in the handle but little or no wobble common with other types of rubber used in props. Each piece is exact in size scale and appears authentic even in close-up. The axe pictured below was cast from the US Army issue axe my father carried in WWII. Check out the weights below in comparison to their “real” counterparts.
We also cast “thinner” props in a urethane resin that cures to a slightly more rigid plastic; Smooth-cast 60D. This product is typically caramel in color but we generally add tint to the object turning it black or shades of grey depending on the individual piece.
For the C-1520 we can add in “Silver Bullet” cast powder to give a metallic sheen to certain parts of our props, such as the hammer head and the grips on the derringer below. The urethane plastic we use can also be painted. The paint of preference is the type used on automobile bumpers and can be found in the auto section of most large stores like Target. Enamel paints sold in hobby stores also work just fine. Really any type of plastic paint will work but the ones mentioned above will flex better and will need less touch-ups.
