vortex gun + co2 tank

Unread postAuthor: the cats in the bag » Wed Mar 12, 2008 8:04 pm

I have been thinking about building a vortex gun with a co2 chamber attached. every one that i have seen is hooked up constantly to a air compressure, is this realistic.

It might freeze the chamber and blow up you might need a regulator.

You can tell how awesome a cannon is by the pressure used.

I know i need need a regulator, but thats a new possibility to explore. but unfortunately not even sch 80 would withstand 2000 or so psi. it would be sweet though. :twisted:
p.s. i mean do you think i could get any shots out of it?

I guess so it would just be inefficient doesn't it cost how ever much money to fill them back up? I think you would be better off with a fire exstinguisher that has a shrader valve in the bottom.

P.S. you should use a tank slightly larger than this this thing doesn't hold too much air. You can also see the tip of the shrader.

Firstly, CO<sub>2</sub> tanks will never pass 1000 psi in any normal conditions (i.e. not thrown in a fire), and run around 800 psi at room temperature. Even SCH 40 steel will hold this with no problems. I'd advise against using PVC at all when you have a CO<sub>2</sub> tank as a pressure source.

If you have a bulk CO<sub>2</sub> tank to fill it from, this design will work fine. If not, it would be annoying to need to refill the small tank. CO<sub>2</sub> is stored as a liquid, so you'll get a lot more shots than you would from an equivalently sized air tank (unless it's liquid air :roll: ). Also, your first post might confuse some people, as you omitted the question mark at the end of the last sentence.

I'm saying he could use the fire exsingusher if he had a device to get the pressure up high.

Remember that dry chemical fire extinguishers are only designed to operate at ~200 psi. CO<sub>2</sub> fire extinguishers, while much more difficult to find, are rated for about 1000 psi.

As far as getting the pressure up high, a 1000+ psi homemade pump is quite possible, with a good design and the right materials.

A fire exstinguisher would be better.

DYI, its a question.

and a co2 tank is 950 psi. i was wrong but thats pretty close to a thousand. :cussing:

vortexes only need a constant flow of 40psi.
