Hi everyone, I bought some rapid mold after it was discussed on here some time ago, it sat dormant for quite a while gathering dust and then I ordered an Ork Big Trakk from alexprintposter on ebay.. it arived in great condition though I discovered it was missing a small piece of trakk... I informed him but didn't want the refund he offered me.. (he's insisted I have free postage worth £5+ with my next purchase anyway)... so why didn't I want a refund.. well... I had remembered I had instant mold:     I found rapid mold really easy to use.. I wish I'd had the confidence to use it before! It took me 3 attempts at casting to get a piece I was satisfied with, but that was a learning curve (and greenstuff is really cheap from non GW suppliers so didn't matter that I was making mistakes). I admit the underside of my chosen piece isn't so well detailed as one of the other casts - but since this will be impossible to see when the model is built I figure it doesn't matter as much as the snug fit and topside detail. I wish I'd begun using rapid mold ages ago - I could have taken casts of grenade launchers, melta guns, the decent catachan legs etc and saved myself loads on buying from bits stores. I'm planning to make a load of 'dead' guardsmen and orks - I plan to take casts of these so I can litter my games table with the agonising screams and stench of death that a true grimdark battlefield should be covered with. Anyways, I'm digressing - what I'm trying to say is get yourself some rapidmold and make yourself some cool stuff for cheap! |

Cool, where did you get it from? (Link plz) I am missing a link for a chimera (think I have a spare somewhere), but I like the idea of casting special weapons  |

Ebay has it, I got myself some a while back.
My only issue would be that the parts being made come out a bit deformed, as the Instant Mold is quite rubbery and has a bit of give in it when the green stuff is pushed in. For making spares and replacements, or bits for scenery, it'd be a great way of getting them quickly and cheaply.
As Treads said, get some epoxy putty off ebay instead of from GW stores, it's much cheaper and buying a big roll can cost the same as the little packet from GW.

What about using liquid green stuff?

I think it'd take a long time to dry  |

Can you not use resin instead of GS?

Could do, although you'd have to figure out how to get it in. And not get it everywhere  |

Sorry, i was up sick all night and tired as hell this morning pooping my guts up, god i want to go home... Works killing me! AAAAANYWAY, i meant cant you just make the mold then instead of cramming in GS pour in some resin? Or would the resin destroy the mold? I really need to get my silicone molding kit and casting kits sorted out... Need monies!

Not bad at all. Now I need to figure out where I left mine, because the hobby itch is starting again.
I hope to one day make copies of bits like Digits can.

rapid mold is a substance that can be re-used by heating it in boiling water.
Pouring resin would probably mean that the resin would melt or soften the rapidmold and deform the cast.
not sure what you need to create a resin cast.. hint hint ..

I mentioned the silicone but i wasnt sure what rapidmold was... Sounds like you'll never get a great result with it  |

I tried this with some green stuff standard and liquid as well as some two part silicone I think and the best was the silicone it set quicker than the liquid gs and didn't deform the mould like standard gs but does take longer and if you don't lube up the entire area it'll stick and go wierd so whatch out for das

Where did you get the rapid mold? I have been looking for something to help me with bits and such but haven't found anything that works so far. I also have no idea if it is available in the States or not.

Yeah resin.... yeah. Probably the worst thing about resin casting is the silicone rubber. It is really expensive. But supposedly it lasts. So this isn't just normal greenstuff? It's actually called rapid mold? After just googling it I see that there is in fact nothing called rapid mold. Also isn't green stuff called Yellow and Blue in the States? I think the hobby store guy was kind of pissed when I asked about "green stuff."

"Two part epoxy putty" is green stuff.
Rapid mold/mould (sp?) is a brand name (EDIT: I couldn't find any on ebay either... I'm not sure whats up with that)
Silicone rubber, depending on quality, is good for ~30-50 cast depending on how well it's looked after (mould relerase, washed out after use, stored in dark dry cool place etc etc).
If you're after a few odd bits, the rapid mould stuff is pretty good value for money, and quick too. Green stuff moulding takes a bit longer, and a bit fiddlier.
Resin molding is brilliant if you have the pocket and the time for it, and you have a lot of parts to make. I certainly wouldn't have resin cast the example parts in the original post, for example.

Yeah, if you're going to cast resin, you may as well invest in a vacuum chamber and whole shabang. Supposedly you can cast molten pewter into silicone rubber, though I had a lengthy discussion with the hobby store guys on whether it was safe to do so or not.
Maybe Milliput molds would work better since it's supposedly harder when dry?
Also if anybody ever dreamed of being a criminal and casting their own GW miniatures, I'll tell you just don't. Not because it's very nasty and illegal, but because it's actually cheaper just to buy the miniatures. Seriously.

Agreed. It's a lot of hassle to make anything, especially if you're two-part molding it. Curing time is a pain in the bum. And then there's the whole legal side, which i'm not going to bother with explaining, as we all know how that ends |

Yeah, I can confirm liquid GS won't work. Tried it this spring, and it just dried down to a thinner-than-paper layer inside the Instant Mold mold of the part I was trying to reproduce.
