New To Alll This... Well Not Quite...

Hmm, when I said co2 in my post with his 2 options I should have said the gas, it could be co2, it could be air, it could be nearly any gas.

He said he had an air tank. Likely you could refill it with a compressor. Anyways, you could take co2 or nitrogen tanks back to be refilled.

Something slightly off topic, there are 20+ 5000 psi nitrogen tanks in my local fire station. They power the one of a kind sprinkler system there. All I know about it is that it's the first one of it's kind, it's the newest kind of sprinkler system. The nitrogen obviously pushes the water out, but it also makes it one of a kind; the nitrogen comes out of the sprinkler system with the water. That helps extinguish the flames better, much better according to the firemen. It can have the sprinklers on for something like 2 1/2 minutes before it runs out of water. The system only has a 700 gallon tank of water to power it. Compare that to the 40000 gallon tank of a normal sprinkler system. The nitrogen really can save water. ^_^ Maybe this is why I know a lot about gasses...

they used nitrogen to put the oil fires out in kuwait... :blink:

you didn't listen at ALL did you. the output can be regulated to a decent pressure. warn level goes up one, bluesmudge. however a HPA tank also could fulfill my dream of a "self-pumping" gun - this would be perfect for a pool blaster.

Even 80 PSI could make a very powerful water cannon I think, so Don't be getting on me about my attention span.

if 80psi is still to strong, I can drop it down to 50 hehe, that can be done at anytime tho so thats not a concern to me.

the nitrogen tank costs about $4 to fill up each time... with 48cu and 3000 psi, and output pressure set to 800psi, I can get around 500 quick bursts (this is for normal paintball use)

so, for much longer ~70psi shots... total potential time I could keep the trigger open (assuming water is unlimited) should be pretty decent.

and thankyou for those 2 design ideas I will look into them

(could also easily interchange with a co2 tank, however as a gas co2 tends to try to go back to a liquid... and liquid co2 is VERY cold, not even good for a paintball gun im not sure what would happen if it got into pvc piping... :| SEVERE pressure spikes, would need an anti siphon and expansion chamber to hope no liquid co2 would enter your gun)

(it also takes a scuba tank or a HUGE compressor they use to fill those to fill up a nitro tank btw)

I do think the N2O or CO2 tanks would take some time to fill up. However, with N2O, there are two types of if, liquid and dry. I'm not sure if they make them both for paintball. (Sorry, I'm a car person )

80 psi is not too strong. I think my latest gun used over 80 psi, but I'm not exactly sure because there is not pressure gauge and I can only roughly calculate the PSI from the number of pumps. I think 150 or higher PSI would start to get in the dangerous PSI range. 100 should be a very powerful gun, just keep the PSI under 150 and it should be fine if you use it responsibly.

how do you get a high in a pump gun? do you make the pump shaft bigger?
EDIT: or do you just pump more?

I don't know how you "get a high in a pump gun." But I can tell you that I've already said to increase pressure, all you have to do is pump more. Making a larger pump shaft will make the pump harder to pump, but it will use less pumps. That also will increase the pressure for the same number of pumps. All I would do is pump the gun more personally, you don't need to do anything special to do that.

[BlueSmudge]

ok thnx, and sorry again for my horrible grammar and word misplacment, I guess it should of been obvious how to do that

EDIT: Spelling, and of course, grammar.

[Ben]

I think I should also tell you that pumping more does not increase pressure in a CPS gun. To increase pressure there you have to add more layers/increase the thickness. Pumping more only increases pressure in air pressure.

[Hachi-Roku]

errr.... this is nitrogen, or oxygen, of both, NOT N2O (nitrous oxide). You are thinking of wet vs dry port injection as well... this has nothing to do with that.

it takes about 3 seconds to fill the tank up... still tryin to think of a more precise design for the gun however.

[BlueSmudge]

How do you turn the pressure on and off? If you can do it manually, you could make a simple backpack homemade, but instead of a pump, put that container there. Take a look at Doom's latest soaker, you could probably model it off that. Oh wait, sorry, Im thinking outloud here. That wouldn't work. You need a pump to open the check valve on his design. You could use my design for a homemade CPS though, that would work. If you wanted it to be air pressure you could replace the CPS CP with some regular CP's. Tell me if you want me to try and get you a picture. I don't have a digital camera, but with some importing and exporting of my video camera, I could probably pull a photo together.

EDIT: lots 'o spellin'

Just use a 35mm disposable camera and scan the pictures onto your comp. Done.

[BlueSmudge]

My scanner is on my PC not my Mac.
I also Don't have time or money to develope pictures for you

[DX]

well, we can all wait. [Btw it takes only 1 hour to develop pics and costs about 2, maybe 3 or possibly 4 dollars to develop.] But, if your scanner is internal, then using your video camera would be more effective. With a PC you can get a scanner built in the printer.
