This is my mini pneaumatic it has a dasani botte for th chamber 1" fittings the botle is attache dyo the chamber by leaving the cap on putting a litle pvc glue around the cap screw it in to the female 1" threaded then put holes in the cap then pout scrws for saftey i have a 3/4" cpvc barrel and ones sleaved with a blowgun barrel in it it has a 1" ball valve and a bike tire valve bulled through with a hammer it doesnt leak at all and i take it up to 125 psi hope you like the damage picks the ones with the board were darts going through a 2" by 6" the others were done with non-frozen paintballs

nece gun where did you get the barrel

probably off of one of those sporting websites: its a .40 cal blowgun barrell

Ummm I dont think water bottles are rated for the same pressure as soda bottles. Last year when we were making air powered bottle rockets my science teacher said to only use the soda bottles that hold a carbonated drink not to use anything that held something non-carbonated like lemonade, water, ice tea, ect. The non-carbonated ones probably are rated but to a lower pressure than the carbonated ones.

It will still work (obviously if you pump to 125) but I wouldnt pump it up past 80 psi, just because what if you drop it.

yah im careful about touching it to anything when its charged i take it up a 100 psi but there really easy to switch so if it bloes or starts to bulge ill change it and i got the blowgun form my grandpa lol

i just dont get why people use soda bottles for chambers, also atleast put a spring on that ball valve.

The soda bottle is cheap easy to get and mount and it is very safe.

ok , ill take your word for it.

Yeah they are fine,cheap and strong i use them for all of my pneumatics nearly i've only ever had 1 blow out in 3 years and on about 4 cannons thatb have been shot over 500 times estimated.

you should freeze the paintballs and then shoot them at stuff

I like the simplicity of it! Quick and easy, works well.

lol, who cares if you drop it, its PET plastic man, worst case scenario is that the bottle breaks from its threads (weakest point in a soda bottle pneumatic) and shoots off behind the rest of the gun

ive dropped my inline pneumatic spud guns countless times, only sprinkler valve cannons though. the only thing that happened is the threaded piece from the chamber to the sprinkler valve broke off and shot backwards, no violent explosion

i made a pneumatic sniper rifle for paintballing and i told my friend not to use it above 80 psi. I went upstairs to get a soda and when i came down he was like dude i got it to 140! Then it exploded. Little shards of PVC went EVERYWHERE. he had a piece stuck in his leg sux 4 him

What type of PVC was it?because 140psi should of been ok if ti was sch 40.Because they run huge safety margins,it takes 3x the safe runnig pressure before it is said to explode.

Good work, excellent example of the KISS principle.
