This is an air cannon that I built this summer to shoot mini tennis balls to my dogs. Of course I also shoot other things like potatoes, tomatoes, apples, etc. Hope that you enjoy the slide show.

Interesting gun, though if you build another, give it a better design so it is easier to hold, carry, and then shoot. My firsdt air gun had no stock, my second had too big of a stock, and my last gunI built is sooo freaking huge, I put my arm through the stock so I can get some support. So just keep in ming, any gun design that is preferably compact, small, easy to wield, and shoots well is great. Nice gun for a first though ;-)
Thanks for the tips. It is a bit hard to carry, but I had built smaller hand held cannon that was that had a large handle to hold onto. On this cannon I wanted to make the tank directly behind the valve for best air flow, so I made a tee shape which was one of the most compact designs possible.
I just finished version 5 Air rifle, and is is mostly S shaped. the top of the s is extended into a barrel, the middle of the S has a trigger, and the bottom of the S has a 2<em> wide chamber. That is how mine is compast ;-)</em><br/>
That sounds like an awesome cannon. You should post a slideshow of it.
One problem: The tests I've done so far let it only shoot 20 ft at 30 psi :( My other gun goes like 100 ft at 30 psi... I might need to do some more tests.
What are you shooting out of it, and what kind of valve are you using
Um... a tight wad of aluminum foil works well, but not in my compact gun... They both have the same trigger, a modded sprinkler valve.
Try a piston valve
Can you point to a source for a piston valve?
Hmm... It sounds like a great cannon that should shoot more than 20ft. at 30psi PS The Aluminum foil sounds like a great projectile to try.
Oh haha... I know this is an old post, but I found out that only half of one of the end caps was glued on. I applied glue all the way around, and it works fine.
Cool, now are you talking about your version 5 air rifle?
I think so. The compact version.
Should I like try a video? or slideshow?
Yeah, that would be great. I really want to see what it looks like.
Sorry, Currently working on an 'ible :D Remind me after I post it :P
Ohhh ok.
I tested it and what works great is 2 90 degree elbows next to the tee
Yeah&nbsp; ! thats good advice My best gun so far i took a bb gun pistol apart and used the handle from that as a Grip and mounted the piezo behind the trigger so i can use that !<br /> <br /> Always a good idea to have a Sling and a stock !&nbsp; A good idea for a stock is to cut a slot down&nbsp; a piece of pipe Heat it up and push the pipe together and tape it .<br /> <br /> Works great<br />
Could this be used as a confetti canon?
here's mine you just duct tape it to an air compreser aim and fire
An Ideo!
My first burrito blaster that I am in the process of building.<br />
What size is the barrel
Check the coments below
Ill have to check it out it sounds cool.
How much did it cost to build and how long did it take.
It cost me around 60 dollars i think. But i could be wrong i built it a long time ago and cant remember. I took me five minuets to put the parts together an 2 hours for the glue to dry. Although most PVC cements take longer.
what is the diameter of the barrel?
For this cannon, i use 2in. barrels and 3/4 in. barrels
I tried it and found you can use two 9 volts instead of three.
i would pneumatically mod the sprinkler if i were you
I have actually done that and it worked great, but i did not mod the sprinkler valve on this cannon because i liked that i could fire it 50 ft. away behind a shield for protection because i used this cannon for experemental shots that were very close to the target.
Yeah, that is what I use at low pressures and it works great, but sometimes at higher pressure it doesnt open as fast. I just built a new more compact version with a metal tank and for that i am using a quick exhaust valve. I would recomend using a quick exhaust valve they are sooo much better and dont need batteries.
how do you power the sprinkler valve ?
Sorry aubout the late reply. Here is a diagram:
