WOWWWWWW. try tank armor as your primary target.

keep bringing up the pressure untill.... alas, golf ball through tank armor. then take it to the US millitary and say.... umm............ my homebuild golfball cannon just owned your tank........

kidding. i dont think anything pneumatic is going to penetrate tank armor anytime soon.......

anyway, that owns. i hope you can find a way to take it above 300 PSI, i want to see this thing at like 500.......

A 1200PSI cannon shooting reinforced darts could possibly

take it above 300 PSI, i want to see this thing at like 500.......

I agree, although that would be insane

Has your compressor arrived yet?

Nope. Even with 1200psi steam in a 3600 ci chamber, with a 10 pound projectile, a burst disk valve, and a barrel 100 feet long, you wouldn't get near the kind of muzzle energy and velocity necessary to penetrate tank armor with a finned and saboted DU or tungsten round. 365 000 ft/lbs would be interesting though... but I would agree that no pneumatic gun will be achieving that kind of power any time soon.

I look forward to seeing damage pics from this gun at 300 psi.

...But it could blow their treads off

Keep in mind there is a difference between a fire extinguisher's RATED pressure and TESTED pressure. Most of the tanks I've seen only list a test pressure.

Edit: Some how I missed the "Air tank" part of your post. Sorry, you should be fine. Good looking gun too.

[DYI]

Most FEs that I have seen are tested to 585 psi, which is far more than their working pressure of around 195 psi. This doesn't mean that they are rated to 585 psi, as they could have burst at 590. He should be fine at 300, although this is higher than the rated working pressure. I would assume that a fire extinguisher's working pressure would be about 1/3 of its test pressure which works out to (probably not coincidentally) 195 psi, which is the pressure that they are filled to.

Is it an FE? I thought it was an oxygen tank that firefighters carry around on their backs.

[spud yeti]

No, I think its a FE, because he said "firemans tool" or something to that extent. I doubt any fireman would want to carry that on his back anyways

[potatoflinger]

Actually, I just re-read the description, and he said it was rated at 2216 psi, which is way more than a fire extinguisher, also If I were a firefighter, I would want to carry an oxygen tank on my back, it would save my life.

[spud yeti]

would want to carry an oxygen tank on my back

yeah, but not that size!

[paaiyan]

That's nice, i like it a lot. About how much does it weigh?

[potatoflinger]

Well, firefighters have to carry enough oxygen for two people (In case they rescue someone).

Have you ever seen a fully dressed fireman?

[randompkguy]

I'm positive that that's an oxygen tank...cause I weld, and oxygen tanks (on torch rigs) are pressurized to around 2000 psi so that the gas liquefies. Also fire extinguishers mainly use co2 which develops 800 some psi at room temp, not 2216....

[frankrede]

Its a oxygen tank.
Don't listen to them, I am interested in a career as a firefighter, and I know my fair share of information.

[spud yeti]

Its a oxygen tank.

No its not, its an oxygen tank.
