Here is a pop off valve you could use.

yes but it is only 125 psi. and that is nowhere near enough to fill a chamber.

So it would be like this in a parts list. Ball valve, pipe, T with the 800psi pop-off on the top, pipe, threaded end cap. That would work but you would need a pop-off on the chamber as well.

You guys are tards...

Remember how it was mentioned that liquid CO2 is needed to make dry ice? Then you take the dry ice and let it turn to a liquid? Why not skip the solid form and put it in as a liquid eh?

You need a metal pipe capped on one end and a ball valve on the other. After the ball valve you put a male quick-connector for air compressor stuff. This will attach onto your chamber and dumped in by the ball valve.

To fill this you need a 20oz CO2 to NPT fitting. Then you put a ball valve and a female quick-conector on that end. You take the small CO2 tank assembly you made and pop it onto the 20oz CO2 tank assembly, open the ball valves, and turn it upside-down so the small tank is down. Give the liquid some time to settle and shut the ball valves again. Pop the assemblies apart and plug the small one onto your gun and open that ball valve to pressurize.

The point is that all you have to do is drop some dry ice in, which is easy to obtain.

dosnt look like u guys are still posting here but... well i have been planing all in my head about making a portable co2 powered spud cannon my idea was to take a co2 tank from a paintball gun and either find or make a fitting an regulator where i could regulate the high pressure in the tank down to about 90-110 psi then connect it to my gun but i could never find a regulator to fit on a paintball co2 tank so i gave up then the other day i was browsing the web and found this site rather expensive but it has exactly what u need to make a portable co2 spud gun
http://www.beveragefactory.com/draftbee ... /co2.shtml

copy that into ur browser they sell nitrogen tank co2 tanks and regulators for both and see what im gonna do when i get a few dollars is buy a 10 lb alumnum co2 tank and a regulator and the regulators can handle the high pressures and drop the outcoming pressure pretty low all together the setup im plkanning on gettin is about 130.00 not bad but thats a 130 dollars i dont have right now so yea theres an idea check it out

use a brass valve, there rated to like 4000 psi
my parents own a fast food resterant and we use dry ice to make co2 for the soft drinks. You just pack as much dry ice into the tank as possible and wait over night. :D

1. Don't double post.
2. Why don't you try your dry ice idea. It'll only blow shrapnel all over.
