a very high power paintball gun. can b pumped up to 100 psi safely. Be careful though it is very dangerous some how it managed to shoot a paintball through a bike helmet at 30 psi (not sure how that happened)

also i will give the instructions for a barrel that fits a paint grenade and shoots it 100-200 feet fairly accuratly but you have to use a tippman squadbuster take of the mesh then pull the pin out and make straight instead of bent and slide it down the barrel

a shorter barrel makes it more accurate becuase it is overly poweful with a long barrel and i will get video of it

Step 1: Getting Materials

2 9-inch long 3-inch diameter schedule 40 pvc pipes
2 3-inch diameter schedule 40 pvc end caps
2 1 1/2 to 3/4-inch reducing bushings the 3/4-inch part threaded
2 metal 3/4-inch pipe nipples
1 3/4-inch ball valve (can get an electric sprinler valve to have an electric tigger)
1 1 1/2-male threaded adapter
1 1 1/2-female threaded adapter
1 1 1/2-inch to 1-inch reducing bushing
1 1-inch to 3/4-inch reducing bushing
1 3/4 inch pvc pipe (watever length you chose but longer makes it stonger to a point)
1 tubeless tire valve
1 thing of pvc cement
1 thing of pvc primer
1 roll of teflon tape
1 0-160 psi gauge (optional if your pump has a psi gauge your fine)
1 t connecter 3*3*1 1/2
Optional(for paint grenade launcher)
1 female 1 1/2-inch adapter
1 1 1/2-inch pve pipe(any length)

Step 2: Building the Pressure Chamber

All of this is assuming you know how to glue pvc parts together

first cut the rubber off the bottom of the tubeless tire valve but leave it around the sides then take one of the end caps and drill a hole just about the same size as the tire valve with the bottom cut off a little smaller will work better then hammer it in then glue the endcap to one of the 9-inch pieces then glue the nine inch piece into the t connector nows when you wanna decide if you want to put a psi gauge on or not. if you do drill out a hole into the other end cap and thread it in
(if you cool it and it fits snuggly then when it heats up it will ave a very tight seal) then glue this endcap to the remainig 9-inch piece then attach it to the t connector(if you dont want the psi gauge just glue the parts together the same way just skip the drilling part) then take one of the 1 1/2 inch to 3/4 inch reducing bushing and glue that into the t connector

Step 3: Attaching the Barrel and Valve

ok now you have to take one of the 3/4-inch pipe nipples and screw it into the reducer attached to the t connector then screw the 3/4 inch ball valve into the nipple. Then attach the other nipple to the other end of the 3/4-inch ball valve. then attach the remaining 3/4-inch to 1 1/2 adapter to the nipple. then the 1 1/2 male threaded adapter. Then attach the 1 1/2-inch female adapter to the male one. Then put a 1 1/2-inch to 1 inch reducing bushing. then put in the 1-inch to 3/4 inch reducing bushing. Lastly put the 3/4-inch barrel in that and your done.

Step 4: Optional Paintball Grenade Barrel

just glue the 1 1/2 inch barrel to the 1 1/2 female threaded adpater.

Step 5: Your Done

now all you need is a bike pump or an air compressor and both barrels just screw on and off so you can interchange them
and about the paintball barrel i haveonly come up with one problem and that is that the gun is so powerful that accuracy is kinda questionable now a shorter barrel would in theory help
if you freeze the paint balls.... when you shoot it it would probably fire more accuratly... i havent tried but i would think more mass might help
nope because freezing it dozent change the amount of mass it just changes it from liquid to solid
It might help to freeze them, I think. Paintballs are water based and water is one of those compounds that gets less dense when it solidifies. Maybe this would help the paintballs fit better inside the barrel. Or get stuck.
heheheheh go buy some rubber paintballs that the cops use for crowd control......
<p>I bought some black balls advertised as &quot;riot balls&quot; on Ebay. They seem to be a nylon-type plastic, very hard. The softer balls are sold as &quot;reballs&quot;. The black balls are dangerous.</p>
I thought they used pepper balls.h
Also rubber bullets.
And bean bags!
no, if they wanted to blind them, they have mass amounts of teargas, mace, etc. I've seen riots get sprayed with GALLONS of pepper spray, trust me, pepper balls wouldnt do any good, you couldnt put enough pepper in one, and its hard to hit someone in the face without putting their eyes out lol.
actually he is right the police use paintball guns with a special pepper spray paintball that is presurized so it sprays out on impact and hurt there eyes if they are anywhere near
there called pepper balls and when the balls bust they vaporize and they act like being near onions except it irritates ppls eyes rly bad!
This topic is so old.
sooo......
oh, sorry. but how is that very effecient? maybe for long-range?
no its for taking out smaller groups in populated areas so not really good for use in a riot situation
well maby sometimes they can use it for like big riots and have "sniper paintabl guns/markers" and cops shoot the "leaders" of the riot
oh. but I do know that rubber paintballs exsist lol. interesting fact: my dad used to be on a pro team, have a $2,000 gun, and play like 3 times a week.
Do a search for Reballs. They're for paintball practice. They're hollow bouncy rubber paintballs.
oh.
So, HAH!
yes police do use pepper paintballs go to www.rap4.com and see for urself
dog the bounty hunter uses a pepperball gun sometimes!
but water gets bigger when it freezes
That's the point. They get bigger and fit better in the barrel. But this topic is way old.
wouldnt it break the skin then
I don't think the purpose of the Instructable is to shoot people. It does hurt to get hit with one though. Paintballs themselves can break the skin.
he means "wouldn't it pop the paint ball membrane?"
Gotcha. Here's my solution to all of the problems: Why don't all of the skepticals invest one paintball into the experiment. Put it in the freezer. See if it pops. If it doesn't, put it in your marker and shoot it. Compare to a paintball fired at room temperature. If you don't have one paintball to spare, then you don't play enough to be commenting. But this topic is way old.
yeah but freezing compacts the liquid and thus with the freezing it shrinks them, which makes their mass more focused on the smaller size which would proportionally increase its weight
freezing paintballs make the balls expand and bus in the barrel or hopper
sorry buddy but it does the opposite. freezing paintballs makes them harder and more difficult to pop. because of the semi hard shell on the outside of a paintball it does not swell or expand unless soaked in water. paintballs are also not filled to maximum amount for the reason of playing in various tempatures including freezing
the paint want freeze!!
lol thats the point so they are like a brick hitting you
im sorry if i had to be this exact but, the shell itself hardens making them harder to pop. and i know ive been playing paintball for 4+ years
yes but it still expands! dude i ow a paintball feild in my town ive worked there 10yrs and played paintball since it was invented! I DEPENDS ON WHAT KIND OF PAINTBALLS YOU USE WINTER SEASON PAINTBALLS FREEZE AND SUMMER BALLS EXPAND!
every kind ive ever bought from cheap paint to expensive feild paint always hardened but never expanded
o ok i depends on conditions in the freezer i guess..... i guess in my freezer theres alot of moisture in the air then it freezes with the water expanding and hardening.
Boys I have built a air cannon that can shoot pop cans, water ballons about 200 feet actuality.<br /> <br /> The Cannon<br /> 40 in barrel<br /> 2 in ball value<br /> 20 in long 4in pipe for air chamber.<br /> <br /> I use dixie cups to hold the paintballs in the barrel but they spread out over a large area 100 ft out.<br /> <br /> I had a fire based gun. they suck go air and go long barrels it looks cool and you can shoot farther with practice and arc.<br /> <br /> freeze balls and shoot them at people you become very unpopular.<br /> <br /> <br />
Quote: "some how it managed to shoot a paintball through a bike helmet at 30 psi (not sure how that happened)" Bicycle helmit? Surely not a DOT approved motocycle helmit.
You were able to hit through a helmet because helmets are designed to absorb shock from something blunt like a curb and spread it over a wide area, instead of withstanding a puncture-like damage.
paintballs dont freeze all the way in a regular freezer. i had a bag of them in a deep freezer for over 3 months. i put them in liqid butane, its easyer to get then nitrogen
Try putting them in liquid nitrogen :D
ah sorry, but freezing something wont actually change the mass, just the density of the stuff
It will make them hurt like HELL!
haha good point
don't use a ball valve, by the time you have it opened all the way the projectile has already left the barrel. use a pnuematically modded sprinkler valve (google it if you dont know what it is i dont feel like explaining it) it will open <strong>SO</strong> much faster which will make it preform like 10 times as good<br/>
make an aerosol compression champer with a spin flint to ignite it. its indtant cumbustion and instant release.
im working on a second version that will use a sprinkler valve with a light switch for a trigger and putting on a gun stock and using an automatic shutoff valve to fill the resovior that goes to the gun from a co2 canister so i could get multiple shots quickly and more accurately
if i make the berrel wider and shove it full of paintballs would it work as a spred shot
no. unless you wrap the balls in a rag like a grape shot from civil war times. otherwise the pressure will escape or the paintballs will fly eraticly
