Lower Pressure Feed plan

Unread postAuthor: thomasc3uk » Wed Nov 01, 2006 12:10 pm

I've come up with a design for a BBMG. I've made a potato sniper rifle which is pretty cool, but now I fancy a crack at a BBMG
A magazine would have a BB sized hole in the barrel. The air traveling over the hole would suck the BBs up and out, then fly out along the barrel.
Would this work or not?
Diagram is attached.

It can work, and it's not too uncommon (I think)

It will be less powerful, reliable and have a lower capacity than one of the more complex designs though.

Would it be more or less or aroun d the same power as a cloud?
I could beef up the size of the reservoir up. I wonder if there's a limit as to how big it is. I suppose if it was too big by the time it was nearly empty the BBs wouldn't be sucked out.
Thanks for the reply.

Correct me if im wrong but i don't see how this design is any more better than a cloud but i dont see how the air would "suck" up the bb's. There is a higher pressure above the clip and a lower pressure within the clip what makes the ammo come out of the clip? I really don't see how this is a good design, because say the reservor is chaged to 100psi when it loses 3/4 of its volume the pressure will be 2.5psi. So you would need a big resivor to get like 30 rounds out. Personally id vertically feed it.

Thanks for the advice. I'll probably jsut make a cloud or vortex instead. I thought the air going over the hole would suck them up, kin of like on "Mythbusters" when they blew air over the hole in the aeroplane and the coloured smoke was drawn out.
Thanks for the advice anyway :)

Yeah go with a cloud. They are easy and cheap. I don't think air passing over the magazine would suck them up, it would probably do the opposite and air would push them down.

Hey no problem. :D As for mythbusters sure air can bring out other gasses but here you are trying to bring out heavy objects. Go with cloud or vortex, or you could flip the mag over and have verticle feed or just put a spring in the bottom fed mag.
