A Makeshift Cannon

I’ve been a little low on ideas lately and couldn’t find anything worth modelling, so naturally I’ve decided to make a 50mm cannon and model it.

The barrel is made of rolled paper, the breach is actually a piece of a tree branch nailed in there hard and it’s shooting rocks instead of shells. The propellant is my own composition, called Red Powder (guess what color it is), and it’s ignited electronically using those wired match thingies you can see on some of the renders.
