Help needed: Moulding detail from one shield to transplant onto another

[myincubliss]

I've been trying to make one-part moulds using Bu-Stuff to transfer detail from one shield to another (a lion, for my ASOIAF Lannisters), but it doesn't seem to work as I'd imagined - has anyone else managed something similar and can proffer some tips, or am I on a fool's errand?

Full trials are at http://deadleadproject.blogspot.co.uk/2013/06/experiments-in-one-part-moulding.html, but it's largely encapsulated in this picture:

Being a little older in the tooth I have never used, or even seen, either blu-stuff or liquid greenstuff.  I have however managed to do similar with just good old fashioned green stuff.  Grease master, cover in GS, leave to set, push in fresh GS and either A: (tricky) transfer to new shield whilst wet or B: let set and then transfer over.

Two-part silicon is what you want:

I've had good success with Instant Mold from Cool Mini or Not:

Or you can buy the same material somewhat cheaper here:

I love the Insta-Mold material. I've used it so often it has paid for itself many times over.

Get two part silicon mold putty.  It's the consistency of silly putty and hardens to a flexible mold in 5 minutes once mixed.  Buy in bulk as the stuff from cool mini, and other shops is the same stuff, rebranded and repacked (more expensive)

Then you can use miliput or any putty in the mold, even two part resin.  Miliput is great since you can use water to make it more of a cream, and flow it into the molds with a piece of plastic.  Easy to sand too once its dry to make the pieces thinner.

Since it is a one time part, you have another vote for insta-mold.

Siligum will do the trick.

No need for the resin, just use GS.

So the collected wisdom of the LAF is that it's a Blu Stuff issue and not something I'm doing wrong (that's pretty much the opposite of what I was expecting  ) - my Green Stuff and Instand Mould have been packed away after my young lady wanted some flat surfaces back, so I'll have to dig them out and have another try...

Also lubricate the mould to aid release... warm some vaseline and just rub a very small amount over it before adding the casting medium, or even a quick short spray of a wax based polish. I'd be tempted to use miliput and miliput, so long as it's lubricated it won't stick together

[myincubliss]

I've used milliput in Blu-Stuff moulds before, so I might fall-back to that if (hopefully not when) my attempts with instant mould and greenstuff (now located) don't work out satisfactorily...

I would use Instamould, itīs perfect for this simple one part mould.
And reusable, if your not happy with the mould.

Hereīs a short tutorial:

Right, I've taken everyone's advice and I've had another crack - using Instant Mould and proper green stuff - long story: http://deadleadproject.blogspot.co.uk/2013/06/experiments-in-one-part-mouding-part-two.html

Short story:



We'll see how they dry, and if I can trim them down to superglue on to the receiving shields. If not, I'll have a crack at trying a thinner layer of green stuff in the mould, and transferring it to the receiving shield whilst still wet...

I would have a go at filing the back part off the shields you have made. I use procreate, which can be filed better than green stuff, but I have heard that mixing miliput and greenstuff works fine, and gives a harder material, so easier to file. File with a large metal-work file. They look really meaty and imposing, but you can do really fine work with a huge file. Plus a half round file will make the curved back surface easier to make.

I got better results when I combined Instant-Mold with GF9's grey stuff or Magic Sculp. The copied pieces' details ended up crispier than those I did in green stuff.
