Thanks again fellows!!!
About the badge...
-I sculpted the ‘tooling model’’ with a hobby shop product named Sculpey- It’s like modeling clay made of plastic that you bake in a oven to harden.
-After it was baked I mounted it to a scrap of board and made a Sculpey "dam" to contain the silicone.
-The Silicone mold material was simply high temp gasket sealer from a auto parts store, comes in a tube.
-I globbed it on, tapped it down, forced it into the detail as best as could with my fingers, and tapped again. I would wet my fingers before touching the silicone to help keep it from sticking to me.
-I melted a old roll of solder wire with a propane torch to fill the mold, It actually took a few tries to get a good cast. And it still lost a good bit of detail compared to the model, soft edges, shrinkage, etc...
Having said this I’ve since discovered that “Premol” sculpey comes in color including some that look like metallic silver, brass, copper, bronze, etc...
Next time I make a badge (Excalibur ‘03 perhaps?) I’m just going to use it straight up! Less work, better detail...
