As far as a regulator, you pick up a regulator from Home Depot for $19.00 us. I use that in conjunction with a ball valve to feed my chamber. (All of the fittings I use are in the compressor section of Home Depot.) That is filled from an air Chamber on the top. You can fill it throug the Shrader valve on the one end, or through the fitting which the hose connects to which is used to feed the chamber from the tank. I use ball valves as safeties and to fill things, never as a trigger. I like my cannons to fuction as close to real guns as possible as I am a huge gun nut. That is saved for a different forum. You can see what I am talking about on my website. This would be a great option for those of you with a regular pneumatic spud gun which you do not want to lug around a compressor or a tire pump. I find it extremely affective as viewed under the T-Shirt cannon in the products section of the website. You just have to scroll down to the bottom. The perfomance is awesome. Also, Check out the Spud Pics section, and you will see local Radio Shows who are using it as well. Mr. Crawley from Spudfiles is in that section with his Piston valve cannon. Check it out, and drop him a line from the site. He will help with any questions you might have as well.
Yeah, I remeber those crappy books from when I worked there.
You had a pretty high flow of CO2 going if you were filing that 3 inch chamber 11 times a minute. I won't be anywhere near that kind of flow, the cold shouldn't affect much then.
Yeah lots of people don't realize the gas continues to warm up if they leave it in the gun for a few seconds. It can make a big difference in some guns. Thanks for the info on your personal experiences.
Trying to figure out how to make a SCUBA first stage regulator work for portable charging station. If only that pesky job thing didn't keep eating up all my time...

For a given pressure, denser gas will give you lower velocity. Helium for example will give higher velocities than air using the same volume and pressure.
Hey I just got one of these to use on a inline vortex bbmg and I have a slight clue that the flow is to low because my bb velocity went to pot even though it's a hike in PSI. Any ideas on a way to et this to work? I was thinking a small expansion tank on the side but that would only allow short bursts. Just out of curiosity has anyone out there looked into modding one of these for high flow?
I'm aware I'm probably going to run into freezing problems but you know...
Why not a big expansion tank
Yes you could. This would allow you to have a greater size tank, without the added weight to the cannon itself. That actually was my original design. Great idea.
an expansion chamber won't help, when using co2 or hpa understanding how it works is important. the following was written on the use of co2 in paintball but it also applies here.
Because CO2 becomes a liquid when compressed, it must expand to a gas in order to be used by the paintball marker. This expansion is not adiabatic and requires energy, causing the tank to cool as heat is used to expand the liquid CO2 into gas. Eventually, under sustained fire, and especially in cold weather, the tank can become so cold that ice crystals form on it. If the CO2 bottle does not have an anti-siphon tube fitted, or is shaken while firing, the liquid CO2 may enter the marker. The liquid CO2 then passes through the marker instead of the tank, evaporating and causing the marker to freeze. This results in large clouds of CO2 vapor ejected from the marker upon firing, caused by the liquid CO2 evaporating in/around the barrel. This is known as "drawing liquid". This can cause damage to internal seals and O-Rings, and can "freeze" some markers, putting it out of commission for some time while it warms back up. Simple operation designs such as in-line blow-back (most Tippmans), guns designed before HPA was more widely used, or guns using 12-gram CO2 powerlets are usually not affected by this problem, but it can still cause damage to the marker over time.For this particular reason, most high-end markers recommend that you use HPA. Technically, CO2 and HPA can propel the paintball, but when high rates of fire are attained, liquid is sucked into the marker which can damage or even destroy electrical components inside the marker such as the solenoid. Never leave a CO2 container in sunlight, as the heat will cause the gas to expand to a dangerous level. The tanks include safety valves in their construction, but there is no need to use them or take unnecessary risks.
With normal back-bottle setups (or, air systems utilizing a horizontal air source adapter, more commonly called an ASA), the less dense gaseous CO2 will rise to the top half of the tank. Normally, ASAs are angled with very slight angles so the gaseous CO2 is always available at the valve of the tank. Special devices known as anti-siphon tubes extend the mouth of the valve, and provide only CO2 from the top part of the tank.
During rapid successions of shots, gaseous CO2 is used up. Liquid CO2 will take some time to evaporate and rebuild the internal pressure. This process causes potentially large changes in velocity and therefore, in accuracy and range.

So What do i need to do? I know the link below shows a guy that used a 5lb co2 bottle but i would prefer to actually be able to carry mine.
I can get i think it's a 2 or 2.5 lb tank from my local oxarc dealer even a 5 lb would be easy enough to mount on your back. heck if i wasn't so fat i could probably even mount my 10lb on my back.

co2 is not very effeicent in cooler weather, in winter one of the things we used to do was take take those hand warmers that hunters use and wrap them around the co2 tank to warm it, just make sure it does'nt overheat and slow down your rate of fire to give the co2 time to expand. other than that about all you can do is either put up with the co2 or switch to air.
and i know a guy that ran around all day on the paintball field with a 20# co2 tank strapped to his back. although he has now switched to a scuba tank.
CO2 is more dense than regular air.

The Question i have here for anyone who has experience with this Item or has access to accurate info is - can this REgualtor work with the newer Paintball Tanks that use compressed air?
The compressed air tanks charge up to 6,000 PSI.
That would give you roughly 6-8 times the use per fill-up.
My PB feild will fill me free/low cost.
That statement isnt true. You should get more shots out of a CO2 of the same size as an HPA tank due to the nature of how it is stored in the tank. Just because HPA is stored at a higher pressure, doesnt mean you get more shots. CO2 is stored in a liquid state, allowing you to hold more potential gas as it expands in the tank. depending on the ambient temperature, your CO2 tank will hold a sustained pressure between 800 psi, and 1400 psi, depending. a simple solution to everyone's problem have typically already been solved by the paintball community. A paintball remote line from the tank, attached to an expansion chamber, before being attached to a paintball regulator should do the trick. you want a regulator with high pressure input, and low pressure output, and preferably high flow. a palmer air stabilizer is probably the best on the market for applications here. if you planning on holding the co2 tank upright you shouldnt need an anti-siphon tube. also, a remote coil should allow enough room for the co2 to convert to gas before it hits the regulator, but an expansion chamber should give some added protection against liquid co2 entering your air-cannon's air chamber.
Old thread mate. You can't just go around correcting every mistake that may have been made in the past - usually, it's best to let these things remain buried in the depths of the forum rather than dig them up.
Quite aside from anything else, I haven't seen that guy around for ages.
Does that thing kinda look like a big cat to you?
