good job

i made one exactly like this one a while back here -v-
http://www.spudfiles.com/forums/viewtop ... tml#296404

ok! so i discharged the extinguisher and filled it to the top with water and then put 150 psi presssure on it and left it overnight
no pressure drop or leaks
since i will not use it at higher pressure then 100 psi, i would consider it safe

thanks to everyone

thanks
the outside looks good, i will discharge it shortly

i bought a 9.5 liter water fire extinguisher it is still sealed
it is proof tested to 500 psi
the gauge is at 150 psi, it sais "overfilled" (90-110 is the green zone)
the sticker on it sais it was last inspected in 1988( :shock: )

so is it still safe to handle, and if so, what could i use it ...

my bad, never heard of ninja paintball
but i still was 78.084 percent right

what tank are you using?
it sais N so i guess it must be nitrogen

@ carlman
no
i tested my pneumatic pellet pistol with a 800 psi tire inflator, and the trigger pull was aboutas hard as my benjamin discovery (3.5 lbs)

i remember this from class when i was about 9
putting 100 bb's in your mouth
taking a pentube
and shooting the crap out of that guy in the back of the class who's shooting spitt balls in your neck and always talking like he's black

i myself made a 800 psi CO2 pcp from the blowgun and a schrader pellet gun setup http://www.spudfiles.com/forums/viewtopic,p,225533.html#225533 (yes they hold up) and a small hammer plus a spring
the valve in a blowgun has exactly the same workings as the ones on commercial guns
i also own a ...

why where are you from Syria :idea: :idea: cuz they the only country that have internet but very slow

No if he was in Syria he'd just go buy an AK47 for $20. Seriously there's loads of places too far away from a telephone exchange to get broadband.

Don't forget with any PCP each shot will ...

why did you make it a private video

according to the DOT specs, Steel 72 scuba tanks rated at 3000(!) psi must have a minimum wall thickness of .164 (0.42 cm)at manufacture, but tend to run thicker, say, .180(0.46 cm) or so.
You can't ignore overall diameter in talking about pressure capabilities.

It might have thicker walls than a ...

1 cm thick walls????

That would easily hold whatever a fridge compressor can put out!

so i wouldn't worry ...

what's the piston made of?

read them and will remember it next time
