Creating a mould? Help!

[Sloth-]

Hey,

I was wondering if someone could help me out with this. I want to make a mould of something I created so that I can make more identical bits with green stuff or putty.
Ages back I saw this YouTube video of this stuff you basically heat up put the thing you want to make a cast of in the middle and let it cool. Cut it in half and bam there's your mould.
I have tried and cannot find it any more or anything similar. Anyone got any suggestions of what it may be, or maybe something better that they use?

Thanks

Sloth!

Yes I think you may be right! Is it good? Does it work well? and if so do you know if they ship to the UK?

Thanks

I've never used instant mold, so maybe someone who has will chime in. There was a video review ( I think on youtube) and it looks good for limited casts of smaller parts. If you need many casts or larger parts, then rtv silicone is probably what you are looking for to make the mold.

They do ship worldwide, however you will have to add it to your shopping cart and go through the shipping methods bit to see what the cost will be.

I've used both instant mould (sold here by some other name, but basically the same stuff) and rtv silicon, and while the silicon is a wee devil to work with, it definitely yields much finer results. however, the silicon I worked with would be no good as a mould for green stuff - it isnt firm enough. Silicon works best with 2 part epoxy resins, which you pour into the mould. silicon mould + resin casting together will yield very nice results, but tend to come in bulk. (e.g. I used them for making about a hundred bases so I could base my 40k army thematically). The instant mould is probably a better bet if you just want 2 or 3 copies of something that doesnt need to be super fine detailed, e.g. some wheels, shields, or similar things.

Ah right cool. Yeah that's pretty much it, I just wana clone the top of this sword really so I can have it mirrored on the other arm haha. I'm sure it'll open up hundreds of other possibilities. I think I shall get the CMoN Instant Mold off eBay right now, since its the same price without the shipping charges.

Thanks for the advice

What's the part, i.e. how detailed is it, the size, any undercuts?

If it's not too complex you can easily make a simple press-mould from epoxy putty and then cast near-perfect replicas from the hardened, lubricated mould using fresh putty.

For a full pack?

Yes its the same thing (full pack), identical product sold by someone who I have bought from many times before

The details quite high on the actual arm, swords pretty plain.

I have Instant Mold, it is interesting to work with. It takes some time to get it right, how hard to press, how much putty to actually use. What I love, is if you need to copy a large shield, you can combine sticks, and later cut the mold in half. I do recommend a water warmer or hot plate to heat the water. The putty works well at a certain temp, I use 155 Fahrenheit , (68.33 Celsius). Do not use putty though that heats or needs heat to cure.
