I wanted a gatling cannon I could hot swap on my Russ's so I sculpted my own and with a little RTV silicone put a mold together and got to casting.
I'm not entirely happy with the cast. A few bubbles were picked up during the molding process and thus carried on to the castings. I plan on making another mold in the future but for now these are good enough for personal use. Once I have a better mold completed I plan on making this commercially available.
