Hey everybody, check out my new pneumatic cannon and let me know what you think. Thanks!

Specifications:
Name: PL 2100 (Pneumatic Launcher)
Setup: Over-Under Style
Chamber: 18”x 3” PVC, 2143.78 cc
Barrel: 26”x 2.5 PVC
C:B Ratio: 1.07:1
Fuel: Air Compressor when at home, or Bike pump when mobile
Actuation: Airgun modified 1” sprinkler valve
Ammunition: Tennis Balls
Modifications: Airgun modded 1” sprinkler valve, Custom built trigger handle with slots to fit snugly onto sprinkler valve cover, Interchangeable barrel ability, Interchangeable chamber ability, Straight style setup ability if U-Piece is removed, custom built chamber support block, two shraeder valves (one on the bottom and one on the left), 0-100 P.S.I. pressure guage, Black krylon fusion paint job.
Comments: This is a really fun gun to play around with. I call it my “party shotgun.” I like making a slit in tennis balls and filling them up with caulking, let it dry for a few days at the slit, and then launch it- makes a nasty mess when it hits a wall or something. It’s just a basic design- my first pneumatic cannon. Very sturdy construction, no loose or wiggling pieces.

Nice cannon! Despite my barrels for aerodynamically better ammunition, I still love to shoot tennis balls!

What kind of distance do you get with water-filled tennis balls? Have you tried water-filled yet, (they go farther)?

Just a little suggestion for next time. Whenever you have a large-diameter barrel, try making a piston valve! They're cheaper and work a helluva lot better for larger diameter barrels. Remember, for a 1" modded sprinkler valve, the flow is equivalent to that of about a 9/16" hole. For a piston valve, you can practically make one with flow equivalent to a 3" hole.

But nice cannon anyway! You still wouldn't want to be caught on the receiving end of one of that cannon's serve!

iv always thorght having a small pipe from chamber to a bigger barel would severly restrict the air flow and reduce peformance

anyway a very clean and kool cannon

Mark, i haven't tried water filled tennis balls yet but how do i do that? cut it and then fill with water and glue the opening shut? Sounds fun though. I love shooting balls filled with caulking, they're soo messy. :twisted: Ya if i upgrade this cannon someday then a piston valve would be my next thing to do, this is my first pneumatic bye the way. Would a piston valve dramatically increase my gun's power? And Experament, The chamber is 3" and the barrel is 2.5" diameter, so i am going from a larger chamber to a smaller barrel. If you read up above at the specifications, my chamber to barrel ratio is 1.07:1. I know, i know, it used to be 1.5:1 but it just took too long to pump up the chamber to 100 p.s.i. when i was out just with a bike pump. I guess if i made a piston valve for this gun i might as well just get an onboard CO2 injection system too for convenience. I have a couple paintball tanks i could put to good use. Any other suggestions? I need feedback cuz i'm new at the pneumatic stuff. thanks.

nice job overall. i really like how you built the blowgun right into a handle on the valve. im tempted to try that on my own cannon. you did a very clean job, keep up the good work mate! :)

to fill a tennis ball with water just go to a pet shop and get a syringe. Stick the needle in the tennis ball and just keep refilling it.

This is an old thread, try not to post in threads more than a couple of weeks old unless you have something really important to add. There are a bunch of people on here that get pissy about that.

It is fairly rare, ive never been able to find any. The internet isnt a bad place to get t though if you buy other exotic plumming parts. even if you did find some at a harware store, fittings for it would be nearly impossible to find.
