The press mold was made using Quick-Sil, a RTV jewelry molding rubber:
This mold was then used to make castings of the weapons by pressing green stuff /brown stuff into it.
The green stuff didin't turn out well; it had air bubbles and was a bit too soft to get a clean impression.
The brown stuff worked great. Though it was bit tricksy getting the epoxy into the mold since the mold material won't stick to anything but itself.
I made eight castings for each side of the four swords I was going to need along with the two swords for the pack leader.
Then the back of each blade was filed down to make them thinner. The two sides were then stuck together using brown stuff. You can see the length of metal paper clip placed as support in four of the 8 castings in the pic.
And here's one of the Hounds proudly holding aloft his newly acquired sword:
Now all he needs is the pistol for the other hand. I plan on making a two-sided press mold and casting it in brown stuff again once the sculpting is done.
