Pwnany First Cannon

Unread postAuthor: Pwnany » Sun Oct 01, 2006 7:34 am

Here's my first cannon that I made not for looks just for performance and I think its pretty good. It shoots marbles, AA Batteries with a bit of tape and anything else that fits. I have made it with interchangeable barrels but at the moment the only barrel I have is the good old marble barrel.

Here it is without a barrel.

Image

Here is a end cap a friend gave to me. Pretty snazzy. (Sorry for the bad quality photo but if you cant tell its a bullet)
Image

Here is a solid metal can I shot at but it was a really bad shot and it hit the bottom and didn't go all the way through. (The further away from the middle you hit the harder it is to break)
Image
Here's the other side where you can see it breaking out the other side just a little. (Just on the edge of the can top right corner)
Image

Here are some dints to some sheet metal after going threw 2 solid pieces of cardboard. The metal was backed by over an inch of ply wood so there is no chance of it making a hole unless it goes threw that much wood. (It wouldn't do that) Those dints are very deep.
Image

Here is the whole thing with the barrel.
Image


Look at this photo of it shooting a big pile of coke cans.

All those cans are ripped to shreds. (The ones that the marble actually hit.)

Later if I feel like it I will put together a video of me shooting stuff.

Nice gun, but if you build it for performance, you should get a bigger and compacter chamber

Looks pretty good too. Nice first gun, I love how it's all metal (at least I'm pretty sure it is) except for the sprinkler.

I don't think it is all metal, because I dont know where you can get black metal like that. If it is metal what kind is it - I want some!

Is compacter even a word? :roll: Anyway Loverly gun there, get a bigger chamber and longer barrel, And to improve accuracy use RNA_DUELERS's rifleing technique.

To be honest I'm not sure what its made out of. However the pipe can be used instead of the coper piping on your house for water so it must be designed to take pressure. On the stickers on it, it says Plasson. I googled it but it doesn't say how much pressure it can take.

Great gun man I am at this moment working on my AA rifle. As I figure it I’ve spent only 30.00 on it. So far but I intend to spend 100.00 I found a way to mount a laser sight not a laser pointer. I'm thinking of putting on a Swiss or Czech bayonet and a led torch on. Right now it's a work in progress. It’s White and I was wondering what to paint it? Camo or silver or black I don’t know? What do you think I might try to put on a gun stock? But I took off the ball valve. And I’m going to add a modded sprinkler valve and the tape is just to see how it looks.

Ps I also have acess to a plastic welder what do you think. thanks
