Pumpkin Cannon

<div align="center">PUMPKIN CANNON

Provided By - John

Here is a picture of a 4" dia coaxial gun with an 8" X 4' chamber. This cannon shoots small pumpkins or large grapefruits over a quarter of a mile at 40 psi. Good fitting and hard pumpkins have flown nearly 1/2 mile at 75 psi, although the short 8' barrel makes for erratic flight at this pressure. The valve is an 8" diaphragm style with a simple 2" ball valve trigger.

alll that I cna really say here guys, is, DAMN!!!!!!! that is a big azz mutha freakin' cannon!!!!! I wonder how much that thing weighs, you should add some more barrel to it so that you can launch a grapefruit about 2 miles at like 110 psi. I bet that it would blow it self back into the ground!!!!!hahaha

i'll give you a dollar if you hold that, and try to shoot it. lol just kidding, i wouldn't try that for 50 bux.

THat is a BEAST. that is awsome. 2 inch ball valves are so hard to open. hOw long did it take you to wear it in?

[Mac_User]

Could you tell me how long it took for you to create it?

[Caboose]

how do you make it

[iamthewalrus]

i think its just a really big diaphram cannon caboose

[spudshot]

first you take a hammer, then you smash all of your fingers.

really, if you plans on something that big and complicated you shouldnt be messing with these, pressure in plastic pipe is a VERY dangerous thing an explosion means shrapnel, and PVC doesnt show up in X-rays, so pray the DR can find all of the pieces

lol yea I woulnt want to be next to this when it goes off

[Brother_Bear]

I read somewhere that ABS plastic is best because it rips rather than shatters when the pressure get to high.

[spudshot]

it does rip, but its not pressure rated, and if constructed right a PVC cannon will never explode on you, PVC is pressure rated, that just adds a safety factor to cannons, and most people will agree only use PVC in pneumatic cannons

[mouse kid]

This cannon is very dangerous looking, but I guess it's safe as long as it can take the pressure. Have you ever found the pumpkins/grapefruits that you fired?
