Power problem

[Schultz]

So Is there a way to rig a air pump to a gun...without it being too noticeable?...any help, Id like to create an air powered cannon that would be used in airsoft... Thanks

CO2 power perhaps?

[Schultz]

Thanks, but thats a little pricey to use co2 for constant fire...I just want to know how airpower could be used...

Constant fire? That is a bit concerning when used in association with 'a little pricey' While a pump will work for 'constant fire' (Mortar support? How often are you firing to be considered 'constant'? it will take a hell of a lit out of you. The only other option for 'air power' (Besides a compressor) would be HPA, costing much more than CO2.

Like I mentioned, a little more information would be very useful. Chamber size, operating pressure, desired ROF, application, etc.

[shud_b_rite]

Its easy, buy a 12volt compressor and a 12volt lead sealed battery and rig up a simple on off switch. The 12volt compressors to tend to break quite easily and it would also flatten the battery quite quickly. As for making it less noticeable, put it in a backpack.

shud_b_rite, while I did make reference to the use of a compressor, with much your use in mind, it would take considerable time to fill a fair sized chamber, and the duty cycle on the compressors is only about 30% as I recall, not to mention a 'good' battery would be about $80. Coupled with the compressor, you might was well use CO2. Honestly Schultz, we need some more info.. a lot more. Help us help you

i heard somewhere that repeated decompression of the chamber on pneumatics over a short period isnt recommened since it cools down the pvc and makes it more brittle?

[Hawkeye]

Make a pump that doubles as the stock. You need minimal chamber volume to propel an airsoft bb. Very few pumps would be needed to bring the chamber up to a safe but effective pressure.

from my experience in playing airsoft with my ghetto guns there are only two realistic solutions (if you dont want to spend a crap load of money). the first it buy a 5 gallon air tank put it in a back pack and strap it on your back. i have to admit its big and bulky but it lets me use my vortex gun in an airsoft match. the second way is to have a bike pump mounted below the gun like a pump on a shotgun and hook it up to a set of 2" tanks on your back. you could use this setup for a sniper or some semi auto gun

A 5 gallon tank to run a vortex? I smell some BS, since that wouldn't hold up in an airsoft match.

Are you really only talking about shooting one BB at a time?

Erm... that runs off a 5lb CO2 bottle in a backpack.... Unless thats not related to that last post.

You could aways use propane canisters from walmart with a regulator.
they should last a while and are what 3, $4 each?
Down side: your gun will stink.

[BC Pneumatics]

Down side is you are releasing flammable gas all over the place. Not to mention you cant use certain construction materials. (most blowguns, etc)

also;

the first it buy a 5 gallon air tank put it in a back pack and strap it on your back. i have to admit its big and bulky but it lets me use my vortex gun in an airsoft match.

That was what I was referring to, if there is any confusion.

As I said in another post, propane is already used in airsoft and paintball guns, they just call it green gas and put it in an expensive tank.
