is it possible to use a co2 bike pump to power a bbgun using a design like this

http://www.spudfiles.com/forums/any-ide ... t7597.html jacks design without the air from the compressor

and haveing a scrader valve ( sorry for spelling ) instead and ataching the co2 bike pump to it. do you guys think this is possible?

I'd guess it would work. I think it might be easier just to use some 12 gram co2 cartridges.

1st off, you're asking if you can pressurize a chamber with something other than an air compressor. What do you think?
2nd, your "sorry for spelling" statement. There's a SpellCheck button for a reason, not so you can say that and type hideously. Mangling languages doesn't get you anywhere. In my opinion, maybe people who can't spell "attaching," or don't care enough to see if they're correct, shouldn't be making anything more complicated than a rubber band slingshot.
3rd, what the hell is wrong with you?!?! You posted in my mini vortex thread about shooting your friends also. If you read (or just skipped to the pretty pictures) you may have noticed that the can is completely ripped apart. That's sheet aluminum, which I believe could just maybe be stronger than human skin and flesh. You think seeing your son-to-be EX friends' skin shredded is funny? Read the damn rules or leave, and don't bring those of us who care about the hobby bad publicity.

If you have a big enough chamber, why not.

My Standalone Vortex had a 2 litre air capacity and was good for around 4 seconds of firing before the air ran out. The design you linked to would likely last less thanks to the greater flow but would be more powerful.

And if they're your friends, please, please don't shoot them :roll:

In a normal BBMG, the bigger the BB chamber then the lower the pressure driving the BBs will be and so you'll get less power. However in the ball valve design, the BB chamber is also the pressure chamber, so you can make it as big as you like without losing performance, and the bigger it is the longer the air will last.

oh i see but wouldn't the chamber loose pressure because if it was a small chamber wouldnt the presure be higher and make the gun more power full and what is a normal bb gun because i know of 3 types a cloud a vortex and the one you dessigned. i think i might go through with this after all but do you think it is worth it

By "normal" BBMG I mean cloud or vortex, those are the ones which benefit from having a smaller BB chamber to give a higher pressure. In my design however, you decide what pressure to put in the chamber irrespective of how large the volume is, and obviously the larger the volume, the more power you'll get for longer.
