Greenstuff Press Mould - Helmet Crest - Betrayal at Calth

When I looked at the picture I was using as reference to paint up my Sons of Horus test marine I noticed his helmet crest was very similar to the one found on the Captain Sicarius metal model, which I have, in that instant I knew I could use it to make a greenstuff mould. The difference this time is that it needed to be a double sided mould.

There are two ways to approach this:

1) Use a single piece of greenstuff, wrap it around the item and press together, then when dry cut open.
2) Use two pieces of greenstuff and cast half the mould at a time.

I decided for the second option.

I prepared a rough block of greenstuff and pressed the item into the mould about halfway, left it to dry. Once dry I prepared a second block of greenstuff and repeated the process to the other side. I used olive oil as the non stick agent and applied to the item and the mould so the they would not stick to each other. Once that was dry I had my mould in two halves.

Now for the test, I prepared some greenstuff, used the oil as the non stick agent and pressed it into the one half of the mould and pressed the second part on top, left it to dry and amazingly it worked very well.

Highly recommended, although this probably wont work for every part you may want to replicate but give it a try.
