S.P.A.M stands for Self-standing Produce Accelerating Mortar.

This was my first cannon, I made it from scrap I had lying around so it has an odd shape...

I had several goals in this project:
-Make a cannon (I really wanted to have one!)
-Make it fast (I wanted to shoot!)
-Make it simple (derived from previous goal)
-Make it powerful -Make it Portable

I met all my goals except the last one, Since i used a very long barrel i needed a bigger chamber (I didnt think of chopping the barrel) so I used the biggest pieces of pipe I had lying around, 4".

The cannon is really heavy, i'd estimate about 15-20 KG so I had to build it in a way that would allow me to use it easily, and since my goal was to shoot far rather than shoot AT things, I glued it in a 45 degrees position. In retrospect I should have made it as flat as I could... shooting AT stuff is more fun...

Overall this is your basic vall valve pneumatic, with a small twist in the form of a weird layout...

However, If youre going to build a heavy cannon, I recommend either this design, or Joel's Mega Launcher.

My friend Broke this gun by breaking off the quick connect adaptor, took me 2 monthes to find the pieces to fix it... the gun is now in working order and is currently used to launch water when it's really frickin' hot...

Love the name of it, looks really nice. Even tho the air running through the frame slows it down a bit. But i like it. You should upgrade the ball valve to a modded sprinkler.

Do you even read the posts? I know you might of missed that BBM but you've ask a couple of those questions already today when they answered the question in the previous posts. Work on grammar and spelling just a little please, sorry to be so critical.

Neat, very cool pneumatic. It would be awesome if you had a stand for it, you know, one with hinges so you can change its firing angle. 8)

Cannons that are their own stands can be very useful I suppose. You could set it on the ground and run a wire and fire it from a distance, great for parties. Just have your friends throw in whatever and you fire it.
