vortex pistol power source

[singularity]

some of you may remember my post about a vortex pistol i planned on making <a href="http://www.spudfiles.com/forums/possibl ... html">here is the thread about it</a>.... anyway i made it but it seems as though the co2 air duster just doesn't have the power to move the bbs. so i need a new air source preferably a cheap and small one that can fit in the grip of a pistol. i know its working becuase using only my breath i can shoot a nice stream of bbs about 20-30ft which means the only possible problem could be the duster. i do happen to have a green gas chamber and hammer valve from an old airsoft pistol but i don't know if has enough flow rate. i can post pictures of the green gas stuff if someone believes they can determine if it will work or not. i have already taken pictures of the chamber for everyone to see

so i need a small portable air source that could fit in a pistol grip or something close to that, any ideas???

edit : the block is made from 12mm layered Lexan with a 1" half hole drilled in it, the barrel is a 6.08mm aluminum barrel i took from an old spring shotgun and sawed down to about 120mm. the vortex chamber it self is about 22cm of 1" pipe with a 1" male threaded adapter on one side and a 1" cap on the other... just in case you were wondering (build time 2 hours)

I dont think the green gas (propane) will cut it. Maybe you could attach a small C02 remote kit and regulator to it and have the CO2 tank strapped on the gun with hose clamps or tie downs.

that would make the gun a bit bigger than i wanted it to be... this is suppose to be my secondary, for when my big vortex gun (or AEG sniper thing) jams/ runs out of ammo and theres people chasing after me. the i was hopping for a small pistol sized gun (but i would settle for mp5k/uzi sized gun) you know side arm sized. im already caring a 5lb co2 tank on my back most of the time and i was kinda hoping on not having to run it off the big tank because i would have to worry about the hose then.

Couldn't you bore out parts of the CO2 duster to improve the flow rate a little?

[mopherman]

You could try using a 12-gram tire filler. you would use a lot of cartridges though.

[turbohacker]

Use one of these on the bottom of your gun, it is disposible, readilly availible, and small. I also think it would last plenty long for your particular gun. (problobly a couple of chainbers full)

origin unknown - sadly i cannot the biggest bottle neck is the part that actually punctures the 12 gram if i were to bore it out even a little more it would weaken it serverly

mopherman - im using a 12 gram air duster there basically the same thing and run off the same cartridges

turbohacker - any idea what type of thread that is, or where i could get an adapter for those things. also what type of gun uses those?

[origin unknown]

The 12g tire filler might have a slightly better flow than the duster based on the fact that both were built for different purposes. You would most likely want to dump the canister faster to fill a tire but you would like to conserve the CO2 by restricting the flow for a duster. It wouldn't hurt to try... well maybe a few $ but thats all you would lose.

[iknowmy3tables]

you'll need some new c02 fill system, did you see if the tube is having trouble bent, or your cartridge is low
maybe you could mod the duster

[turbohacker]

This is used for low buget paintball guns (walmart specials )

They can be baught at many large department stores as well as paintball shops. Here is the only adapter I could find, however I have seen people drill a hole in the side and tap ordinary pipe threads into them.

The only problom with this idea is that you would have to incorperate a regulator into your design because I doubt your blow gun will handle over a thousand PSI.

You could use this small regulator because it hade pipe threads already.?

EDIT: These CO2 tanks are also used for air rifles.

make a custom green gas/propane chamber and connect that to a blowgun.

[singularity]

i have a real green gas chamber and a hammer valve sitting on my desk right now, think i should try it? i could easily mod the hammer valve to be a realistic trigger... i just wasn't sure if the gas consumption would like super cool the green gas chamber.

[potatoflinger]

You should try using the co2 tanks that turbohacker suggested, I think they are four ounce tanks. (They are also used for bb guns.)

[paaiyan]

Yea, those 88g things would work for you I think. They aren't obscenely large, and they're fairly cheap, last time I checked Wal-Mart had them.

The green gas chambers from gas pistols dont even last but a second when they are discharged. My first pneumatic cannon was a piece of 1/2" pvc, some cardboard, and a clip that I used interchangably from my gas gun. I would discharge the green gas and shoot a sabot loaded with BB pellets which proved to be an effective weapon in a backyard airsoft game I played.
