It looks rather simple. But casting it won't be--neither simple or easy.

Anyway, past experience has taught me caution. I think it's best to try a smaller version first. Maybe a third of the size of the adventurer-shooting cannon we hope to replace. But--that's something to talk to others about. *a large arrow is drawn pointing to this last sentence*.

Here is a list of things we will need:

1. Measuring sticks. Our ability to measure exactly is Very Important!
2. Three or four long, thick strips of strong leather
3. Three strong wooden boxes to hold the sand mold. (One for the mold to make the breech cap, and two for the cannon barrel)
4. enough sand and clay mixture to fill the boxes.
5. a barrel of coal dust
6. a) Rod to create the fire hole. b) Iron band to secure the breech cap to the cannon barrel.
7. Trunk from a very solid tree whittled into a cylinder the diameter we want the cannon to be.
8. Two braces to steady the pattern that will form the inside of the barrel.
9. large iron ladle to pour molten metal into the mold. Crane to hold it up. (Hope we don't have to make one of those!!)
10. lots of scrap metal.
11. Lots of luck.
