Not sure if this goes here, but whatever:

There have been several posts on BBMGs lately. I also recall a thread about someone asking about a paintball version and the answer was no; that the paint would break in the chamber. I got to thinking about this and came up with this design.

It's not a typical BBMG type, but is very similar. Would it work?

The hopper attaches to the central pipe, in its designated spot. The paint falls into place and catches on the detent. There is an air hose that connects to the middle section (the piece holding the detent) that runs to a valve. From there, the valve connects to a small chamber, which is powered by regulated CO2 / HPA.

Obviously, I left off some features, such as stock, trigger, etc, but this should give a general idea. It functions like a BBMG, as long as you hold the trigger (valve) it will fire.

The only problem I foresee is the back blast into the hopper.

That, and paintballs tearing against the detent.

What youd need is some form of air/electric powered rotor that chambers and protects individual paintballs, something like this:

Instead of the square edges leading from the hopper to the barrel i think they would have to be smoothly contoured to allow a smooth flow of the paintballs (otherwise they might break). Apart from that it looks like a good idea, maybe a bit wasteful of air/co2 but what clouds/vortexs' don't waste air like a b!tch.

Edit: Bloody JSR strikes again!

Like I said, this is just a basic idea. If I build something like this, it would take a lot more thought.

JSR: That thing reminds me of the centrifugal force cannon the guys built on Mythbusters.

There would be an element of centrifugal force but the power would come from the air pressure in the chamber. Ideally it would not be spinning very fast, I would prefer to add more projectile notches to increase ROF than increase the rotor's RPM. Another advantage of this design is that the flow between firings would be heavily restricted by the rotor thus giving time for pressure to build up in the chamber, therefore more power

Are you familiar with Tippmann's power tube? Would something like that help as well?

No idea, what does it do?

In short, it allows the flow of the air to the round. It narrows at the tip, which allows it to build more pressure, applying the Bernoulli Principle.

It also has a set screw in it to hinder the flow (for velocity adjustment).

Ah, a venturi of sorts? Would it really have any benefits though, we know from even basic pneumatic launchers that the less restriction you have on flow from your valve, the better the power.

Sounds a bit like this device I'd need a chronograph to see the benefits.

It can add up to 55hp to any vehicle*



*Individual results may vary

Benefits? It seems that it would displace the air around the projectile more evenly, making for a more consistent shot. I wouldn't think it would make a big difference, however (nothing that could be seen on a chrono).
