Anyone built one? Anyone built a powerful one? Anyone built a pneumatic spud gun?

Mine is built with 5' of 1 1/2" sch 40 pvc and 30" of 3" sch 40 pvc and will operate with 165psi of compressed air.

We built one that used mapp gas. Piezo igniter...it was bad ass.

Had 6" combustion chamber. Looked like a bazooka.

I have one. Total length is about 6 1/2 foot. 2" barrel 3" chamber, all sch 40. Run it at about 100 psi.

Had all the parts for a propane one in highschool, but never put it together. Olly was the brains behind that though, so it's his fault the ball was dropped. We made several ones that were hairspray powered and screwed around with chamber and barrel lengths. Had a couple that were badass.

Ours is 2" barrel with a 6"x4"Y combustion chamber. Grill igniter and a shot of hair spray. Will launch just shy of 300 yards.

I want to try and build one that will fit a golf ball and run off mapp

Get some of those pool water balls and load it in before you drop a golf ball in. It will launch them out of sight.

Think big. I'd like to build a pumpkin gun.
Multi-staged high pressure air.

Neighbors truck still has the dent.

Spud gun was my 'project' for engineering drafting class. We had to draw and build something so...
Hehe.
Campus police showed up when the class and prof tested it.
Public enemy #1...again.

That's why mine got built. Physics project, wanted to build it specifically for golf balls but the teacher said that was a weapon and it was a no go.

One time I tried to build one for golf balls too and I did a lot of research on it and unless you wanted to use a wad the barrel that a golf ball fit perfectly in had to be specially ordered. Like $60 a foot or something. And I'm talking PVC, special oddball diameter.

turned a chunk of bronze on the lathe for a golf ball cannon more then a few times over the years

I just wanted something easy to draw, fun to build, and a blast to play with.
It wore off. Tannerite is WAY FUNNER!

tennis balls are the way to go.

I can't believe nobody has a video

I saw one once that was made to shoot .177 pellets. That fucker was badass. Sure with I had the tools to put one together.

Didn't know that, never got to the planning stage of it just the idea.

Remember reading it on some Potato gun websites. Guys were buying it though and building some awesome golf ball cannons out of them.

It was 1996 when I made mine. Internet was just a baby...dial-up shit.

Haha I forgot we did that. How stupid did we have to be to think it was ok to shoot the neighbors truck at point blank range?

A few pictures of mine. The air chamber is bias wrapped with duct tape in case of chamber rupture to stop flying pieces of PVC

excuse my messy garage.


The gun is over five feet long.


3" slip x slip and a 3" x 11/2" bushing


3" slip x thread and a 3" cap diaphragm is cut from the side of a plastic waste basket (stiff but still flexible)


Use three pieces of 5/8" heater hose (about 1" long) around the breech end of the barrel to keep the barrel centered in the air chamber.

This works similar to the way air brakes work, it is a rapid release valve, air pressure keeps the diaphragm against the breech end of the barrel and when the air nozzle is removed from the hole in the pipe cap, the diaphragm is pushed back by the higher pressure in the chamber and the air is evacuated through the barrel propelling the potato out at a great speed. The potatoes are cut with a piece of beveled PVC so that they fit snugly in the barrel.

Spud guns really bring out the 10 year old in you.

Nice rack in the background.

Not really, One is a forked horn from Mendocino County, California that I shot in 1956 when I was 12 years old, my first deer. One is a 10 point white tail that I shot at Fort Hood Texas in 1969, first white tail I ever shot. One is a small California antelope that I shot the first time I applied for the draw in 1974 (when Squeky Frohm [sp] tried to shoot President Ford). The racks on the wall mean nothing to anyone but me, certainly not what you would call trophies in the usual sense.
