Best clay molds according to redditors

Btw In regards to miniature casting, whats a good resin to use with https://www.amazon.com/Smooth-Silicone-Smooth-Cast-Plastic-Compound/dp/B01D9BUSI0/ref=cm_cr_arp_d_product_top?ie=UTF8

I wanted to do a quick write up of a fun project I just finished today. I hope you dig it!

I needed bases for my Rogue One figures (Seriously, check out Sun and Skull studios - great stuff!) that came in, but what is this? FFG does not sell extra bases? Well, close enough just won't do, so I did what any crafty gamer does, and I got to work. Let's make some bases!

So the first thing I did was get some Smooth-On Silicone Molding material and some Smooth-On liquid plastic. I wanted to make a mold of a bunch of bases at once, so I could replicate them in batches. Once the product came in, I could start the project.

As far as making molds go, this was going to be pretty easy. The technique is referred to as a "Dump Mold" - basically, we have a fairly flat object to duplicate, and a flat surface to pour the mold onto. We don't need to have the mold wrap around to the other side of the bases, because the bottoms of them are flat.

I used Hot Glue to stick the 8 bases I wanted to replicate to a piece of Foam Core board, and then I used the same Foam Core and Hot Glue to form a box. This is what I was going to make my Silicone Mold from.

Once this was done, I mixed equal parts of the two part silicone material in disposable cups. Being sure that the pink and blue materials are thoroughly mixed together and blended into a purple material with no streaks in it. We then poured this into the box we made, and tamped it down to get any air bubbles out of the mix. This has to sit and cure overnight.

The next day, I was able to break apart my box to reveal a well formed silicone mold! A little flash on the edges was just fine here, and wont interfere with the later plastic pour.

With the mold made and cured, it was time to make our actual plastic material. We needed a LOT less of this to make the actual bases, so I was trying to be careful with my pours. We mixed equal parts of the liquid plastic material together and mixed it well. This stuff is clear out of the bottle, but sets up to make a white plastic when it is all done. I could have added coloring agents to change the white into something else, but I knew I was painting these guys regardless after the fact, so the white was fine.

Pouring the plastic was fairly easy, but I was trying to keep all of the plastic in the mold itself, without overfilling and creating a "bulbed out" look that I would need to file down after.

15 minutes later, my perfect replica bases popped out, and are ready to have some Rogue One K-2 units attached to them!

I hope you liked this little walk through. Give this technique a try, it got some great results. :)
