A 3600 psi bicycle pump. - General

[media]http://www.youtube.com/watch?v=P1m87cdRB60[/media] I had no idea these kinds of pumps existed, now I can fill up my paintball tank for free :)

Oh yikes $200. I guess it'd be worth it if you paintball a lot?

[QUOTE=FunnyBunny;46716639]Oh yikes $200. I guess it'd be worth it if you paintball a lot?[/QUOTE] 280 also, nobody's paintballing at 3600psi (hopefully)

a paintball at 3600 PSI would do some real damage. these pumps are for precharged pneumatic air rifles like quackenbushes. Imagine a pellet gun, except it can do this [img]http://imgkk.com/i/5m8c.jpg[/img] I don't know about you guys, but I certainly don't want to be hit by anything backed by enough air pressure to kill a bison.

[QUOTE=katbug;46716727]280 also, nobody's paintballing at 3600psi (hopefully)[/QUOTE] There's high pressure air as an alt for co2 in paintballing now. Spensive, but good if you live in an area with no reliable source of Co2, like me. Tanks usually go up to 2500psi, as it's compressed air, rather than liquid like Co2. Usually regulated down to Co2 pressures, as the high pressure is the only way to get more than a single full power shot.

I doubt if paintball would last at pressures over ten times of what they're supposed to be used at.

High pressure air tanks for paintball fill to either 3000 psi or 4500 psi depending on whether it's a steel tank or carbon fiber wrapped tank. There's a regulator on the tank that drops the pressure before it exits because feeding that much pressure into most paintball guns would result in an explosion, pressure in the tank doesn't determine the balls velocity.

I knew I wasn't crazy...

I've heard that using compressed air vs CO2 in paintball makes the balls curve in random directions a lot less? Is that true? Thinking back it doesn't make much sense but I was an gullible kid when I heard it.

Thinking back it doesn't make much sense but I was an gullible kid when I heard it.[/QUOTE] Well it's definitely more consistent in terms of velocity because CO2 depends on the environmental temperature for it to boil into a gas where compressed air is already a gas. It's possible that if your CO2 is being inconsistent with boiling/expanding that there could be a correlation between velocity and how straight it shoots. The biggest difference when it comes to shooting straight, in my experience, is the quality of the paint and not the gas you're using.

And totally agree with you on the whole "I'm carrying a bomb" thing. Worked as a ref for a few years and every time I filled someone elses tank I had to bury that morbid final destination vision of the waist level tank rapidly releasing 4500 psi of air, steel, and carbon fiber into my genitals.

[QUOTE=Swebonny;46738112]How the fuck?[/QUOTE] Custom built .458 air rifle. Guy wants less than $1K to build a standard quality one, but he's been too backlogged with orders for the past few years. That rifle there has a muzzle energy of 500 ft-lb/f or so, with a 400gr cast lead .45-70 bullet going 750fps or so. Only good for two shots on a full charge, but enough for bison.

My buddy has a barrel kit and is always making sure the ball barely slips through it. He has expensive gear though so I can't blame him for making sure everything is perfect.

oh god, i am already scared enough filling up bike tires or my car tires, but filling up a tank to several thousand psi.... i would be too (irrationally) freaked out to carry that around on my body

But those can fail. Ever see what a scuba tank does when it explodes and the pressure release fails? [img]http://img.gawkerassets.com/img/18t903x50p10jjpg/k-bigpic.jpg[/img] Fuck that noise. This was a Nitrox tank rather than a scuba tank. They can cause about the same level of destruction if they fail like this

Maybe someone can clear it up.

[QUOTE=Tippmann357;46740732]I'm not entirely sure what safety mechanisms there are on the tanks but I'm sure that's put into consideration somewhere in the designs. Maybe someone can clear it up.[/QUOTE] pressurized tanks generally have pressure release mechanisms that are designed to fail and release the pressure slowly rather than blow the whole thing. What you see there is a result of a damaged tank that should have been thrown away rather than refilled, or a very old tank without a failsafe mechanism.

I've heard of composite wrapped pressure vessels being wrapped in a particular way with a weak point so that if it explodes it fails in a predictable manner and doesn't shrapnel everywhere. I don't know if paintball canisters are designed with that in mind though... [editline]19th December 2014[/editline] That's another (slightly) relieving fact, unlike scuba tanks, paintball tanks are a very thin layer of metal followed by a composite overwrap, meaning that hopefully if it explodes there will be less shrapnel.

I've never heard of an HPA paintball tank blowing. It theoretically could happen but many elements of the design go into preventing just that. Just mind the age and physical state of your tank. A good carbon fiber tank should last 15 years if you take care of it.

Would this work for inflating car tires? I've been looking for a non-electric solution that I can carry in my trunk.

Maybe there's potential for condensation and rust which could cause some damage.

imagine all that pressure released at once inside [sp]your ass[/sp]

[QUOTE=Sonador;46753164]Would this work for inflating car tires? I've been looking for a non-electric solution that I can carry in my trunk.[/QUOTE] you don't need 3600 PSI to fill a car tire. the problem with using bike pumps is volume, not pressure. With either this or a bike pump it'll take around 150 pumps minimum to fill a tire. If you've got a little bitty economy car with little bitty economy car tires it won't take too long, but if you're rocking 36 inch boggers or something expect to put away a weekend over the ordeal.

[QUOTE=Tippmann357;46753174]Any idea if the tanks should be "emptied" when not in use? Maybe there's potential for condensation and rust which could cause some damage.[/QUOTE] Actually storing your tank empty is more likely to cause problems with condensation and dust. There's no harm in partially emptying the tank but it needs a healthy amount of pressure. For HPA you should keep it around/above 50%. I kept my 4500psi tank at 2k for years. CO2 you can store at 100% though, it really doesn't matter at all. Either way, just keep your tanks away from heat sources and out of the sun. Stick them in a box in your closet or something. [QUOTE=Sonador;46753164]Would this work for inflating car tires? I've been looking for a non-electric solution that I can carry in my trunk.[/QUOTE] It would work but it's wildly unnecessary. Most car tires are around 34-40psi if I remember correctly. This thing can do 3600psi. You'd be paying far more than you need to. Also like hydrated said, expect to be pumping for a long time no matter what pump you get. Handpumping a car tire would suck but I can see why you'd want a backup pump. Just don't spend $280 on one, you really don't need to.

I keep a little floor pump in my trunk, a lot of people do. topping up a few PSI per tire only takes about 15 minutes on my car. It's just if you don't regularly maintain it that it takes forever.
