Title: Foam rubber casting tips?
Post by: andalucien on November 22, 2013, 02:29:18 PM
Hey guys, I'm in early stages of working on a display board, and I'm realizing some pieces of it are repetitive and could benefit from casting.  Anybody done any foam rubber casting for wargaming terrain / props?

My current plan is...
1) sculpt repetitive piece out of Sculpey
2) bake sculpey to "freeze" / harden it
3) cast liquid silicone mold by just pouring it around the clay piece in a container
4) Make foam rubber parts in silicone mold.

That sounds about right.   Not sure if foam rubber is what you want.  But it could be.   Does the part need to flex?

Thanks :)  Awaiting delivery of various supplies now...  foam more because it will be large, and i'd like to be carry this thing around and be able to drop this thing and not worry too much about breaking it.  I think that too much solid resin would be really heavy.

What would be the first material that comes to your mind Sam if you wanted something voluminous?

Urethane foamed resin.   Smoothon make a couple good ones.   foam rubber tends to be at least as heavy as resin if not heavier.
