<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?

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

how do you make it

i think its just a really big diaphram cannon caboose

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

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

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

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?

lol that wasnt a dead topic at all yeah and that guy dosent post here this was posted bout 1 year and a month ago do you really think that this dude is still surfin the forums !!!!!no!!!!! jesus make some forking connections
