Basically I was looking at making some moulds of some of my custom bases just to make life simpler and so I dont run out of green stuff, but I have no idea what a good price or a good product looks like. So basically from a few people in the UK who have experience with mould making using silicone rubber and the resin for the casting process, where did you get youre materials from, were they a good price and were they good to use for the moulding and casting process.

Muchly appreciataed people

They sell both the resin and silicone rubbers needed for both parts of the project.

Talc makes a good mould release also.

Hobbycraft Stores.

they sell a variety of material, from plaster, two part silicone pastes and RTV rubber.

Maybe more expensive than online retailers but at least you can see what you are getting.

Thankyou you both, ill find me local hobbycraft and price it against the website. As for a mould release agent, I have some silicone spray used for lubricating guns around (I do airsoft so its all ok.)

See as thats used to lubricate moving parts and prevent friction do you think a misting of that would act as a release agent? (Or to prevent moulds from sticking together)

Just been looking through as well, would people reccomend silicone or latex for the mould? Seeing as latex is one hell of a lot cheaper.

Forget you saw latex. Silicone is the way to go Strength, durability, heat resistance, it's got all you need.

For mould release petroleum jelly (vaseline), talc or ambersil (silicone spray release agent) are ideal.

I would suggest testing your silicone spray on a piece of cured silicone mould to see the effects.

Also, just wondering, are you looking to cast in resin or pewter?

Was looking at casting in resin. Found a nice very runny resin, but it only has a pot life of 4 minutes so would need to be VERY fast. Ideally id rather have a really low viscosity high cure time so I would have ample time to vibrate out the air bubbles in any detail/crevaces.

For ensuring detail is kept I was planning on vibrating the silicone when creating the mould, which invariably would entail obtaining a "personal pleasure device" to provide suitable consistent vibrations until the silicone had cured.

If i did some more complicated designs or thing to put on the terrain I was planning on making two part moulds in order to ease the casting process, which seem simple enough to make.

I have a vibration plate for that.

It's a frankenstein's monster tool cobbled together from a small steel table, a plate (1/2" steel) and a repaired orbital sander.

Concreters often also have vibration plates which are just AC powered solenoids that oscillate at a given rate.
