geez, thats pretty harsh. ANYWAYS i'm not getting involved but i do have a question since the helium atoms are smaller than the air atoms, won't it leak more?? so my question is: is there anything special that you would have to do to put helium in your pneumatic, like would the helium seep through t...

do you have a picture or a link if possible. i think i know what your talking about but i want to make sure.

what if you had a 1.5" in and 2" out for your chamber sealing piston valve? would that be bad? would it be ok if you had 2 valves???

no a burst disk actuatin A PISTON VALVE. sry i didn't make that clear at all

o... well i live in canada and i have never heard of 3L pop bottles, maybe its a approximation from imperial system

ok thanks a lot, so are the npt taps common, do they just fit in the chuck

Hooray, someone donated to me, but who was it???

yeah, i want a signature and i was testing to see if i could cheat the system, how much money do you think i could go negative... hmm...

lol, now i have negative money
