I made a cannon that is the same. Except I didn't have the wood glued to the back.

Sorry but as i said its at my friend's house. By the way we shot it at a 10 degree angle and it went about 50 yards hit the ground and bounced over a pool and a fence.

Hi this is my first post. My friend and I built this cannon a few months ago. It is an extremely simple design. Sorry but the cannon is at my friend's house and I only have a diagram I drew. Hope you like it. P.S.- I use Static Guard. P.P.S.- Sorry for te bad image but you have to open it to see it ...
