Homemade artillery

Feel welcome to comment!
The music is from Battlefield 1942 (EA Games) and does not belong to me.
The barrel is made of 3 inch PVC pipe, the wheels are from a bike trailer, and most of the rest of it is wood. It is powered similarly to a water bottle rocket launcher. Water is poured into the bottle; the bottle is placed onto the cork, insert the U pin to keep form launching prematurely, then fill with air (60-120 psi) pull the cord when ready, and watch whatever you put in the barrel fly. Both the idea and design are mine.

The water is necessary for better propulsion. Since Water does not compress, the air inside the bottle is what really provides the thrust, but the water provides a more solid thing to push against, air pushing on water, vs. air pushing on air. For more info on how and why it works I suggest seeing the Mythbuusters Water powered jet pack episode on Youtube. I might post a Tutorial on how to make your own cannon in the future.

When the desired air pressure is achieved, the U bolt is pulled out with a rope/lanyard, the bottle pops off the stopper and moves forward very quickly, sending anything in front of it (normally I use a tennis ball) out of the barrel and down range.

For the launching, there is no pressure that the pipe needs to withstand, the 120 PSI is contained in a soda bottle, witch is filled 2/3 full of water and placed on a rubber stopper in the end of the barrel. A U shaped bolt is then fed through the 2 holes in the top of the pipe and around the end of the soda bottle. This makes a pressure seal, so that when the air compressor valve is opened, the empty space in the bottle is filled with compressed air.

The Music is the loading music from Battlefield 1942 (which is an awesome game), although the music is similar to BF 2142.

To answer the question about the PVC pipe, I cut the 3 pipe with a jigsaw after drilling holes for the corners. It helps to draw the shape of the cut and measure out everything as I did. For the ends I used a hack saw. Thanks for all the great comments!

give us a tutorial

Pretty cool man thinking about building one kind of like it only i wouldn't use the water to shoot stuff I would just use bottle rockets and crap, thanks for giving me an idea though.

okay.. that is impressive.

[luckyscootboy]

i would like to make one of these please explain to me how the mechanism works

when i make this i put this to my window next to my neighbor :D

[AmazingTangy]

PVC pipe: $40

Pack of water bottles: $30

Tennis Ball: $10

Getting to launch tennis balls at that one cat that always craps in your yard: Priceless.

@BobNO227 i think its only there for easy loading access

Could you overload the bottle with air and make it explode to send the projectile flying?

NICE!
