Molds and casting

[Nocturne]

Hi.
I have a 'template' (Not too sure what the right word is) for making some grenades.
BUT Rather than cast them in resin, I want to cast them in latex (or some other rubbery substance) so that they're safe to throw at people.

Any tips from you experienced casters out there?

www.smoothon.com Try the expanding flexible urethate. You can make Nerf grenades.

Hmm hadn't thought of that... I was more concerned about making the molds than what to cast them out of, I think mainly because I'd settled on liquid latex (something I keep plenty of around for making LRP-safe swords ... and lightsabers)

silicone is probably best for the mold as the only thing that will stick to silicone is silicone itself

I'll second that.. Silicone is wonderful stuff
