I'm in planning stages on an original prop. I'd love to have checkered grip inserts in black rubber. I'd hand-carve the master, but is there a material I can cast that has the give and look of hard rubber and will stand up to handling?
Urethane rubbers are probably what you're looking for, may even be what your original is made out of. They are a two-part material and come in all sorts of densities.
Thanks. I checked Smooth-on now that I had a name to work from. Only downside I can see is the stuff apparently hardens in the can within two weeks of opening it. I wonder if there's a hardware store product that would substitute? But...with the starter kit from Smooth-on being only $25, seems worth it even if you only use it once...
i have put argon from my welder in to paint cans to displace the air and stop the paint from getting a layer of film on top. I wonder if doing that to the part A would stop it from hardening in the container.
