Step 2Mold
Make yourself a mold.
I had a bunch of gypsum cement hanging around, so I made my molds out of it. It was a horrific and almost dangerous failure. Don't do it.
So after that, I got myself some steel. In this case, obtanium resulted in some 1/4" wall that fit my needs. After dialing the tig welder up to its maximum (and finding out that its cooling fan has 3 levels!), I had a mold.
The downside of a steel mold is that the steel holds heat so much longer than the tin, so it takes so much longer to cool. casting sands are a good option too, if you can get some.
