There really shouldn't be that much of a power difference between the barrels, as long as one dart isn't really loose.
Sorry about the crappy pic, I'm at school and I don't have my scanner or my plans.

Thats just what I was thinking. To make it work it would be better to have the air come down one pipe and split in two directions. Working with only two barrels and keeping them as equally distanced from the source of the air is the best way to go. Put three darts down each barrel and you have a 6 shot shotgun. Better yet, instead of the two barrels make PVC couplers and have interchangable 6 shot double barrel clips.That wouldnt work techno. The middle barrels would have the fastest air delivery, and the most air, whereas those outer barrels probobally wont even fire.

I know exactly what this kid speaks of. It could work... it would look badass too. Damn it, now I'm all caught up in this hype! Now I have to build one.My idea was to connect four peices of vinyl tubing tubing together and attach it to a basic pull valve. The barrels would be almost exactly the same shape as Ratchet Blast's but would fire all at once with maybe two darts loaded in each of the tubes. Sorry that I dont have a picture but ill try to get one up.
Not in the game anymore, but it was great while it lasted. Thanks for the great years of fun, NH!

I was wondering if there was something that you could buy that would garentee the four barrels would get the same amount of air. If there is such a thing where could you buy it?

From what I've read of pneumatics, because the resistance is the same (or close to it) in each barrel, the pressure behind each dart should be close to the same, at least untill one dart leaves the system.That wouldnt work techno. The middle barrels would have the fastest air delivery, and the most air, whereas those outer barrels probobally wont even fire.
I'll have to build a small one to test it.

That's what we are saying. The barrels closer to the air source will get more power faster, and they will leave the system. Then your prediction comes into play. The rest of the darts will not have as much pressure behind them when they leave barrel, due to the holes in the system.From what I've read of pneumatics, because the resistance is the same (or close to it) in each barrel, the pressure behind each dart should be close to the same, at least untill one dart leaves the system.That wouldnt work techno.

Well... When the air first enters the distribution system, the air should go to the area of least resistance, which would be compressing the air in the rest of the crosswise pipe. Then, when the pressure gets high enough that the darts offer less resistance than the air, the darts will be launched. From a purely theoretical standpoint, it seems to me like it would work. As I said, I'm going to have to build a test gun to be sure.That's what we are saying. The barrels closer to the air source will get more power faster, and they will leave the system.

The simple way to combat this is to dump the air in so fast that a dart moving will not have a significant effect on the back pressure. Unfortunately, narrow vinyl tubing is not going to cut it for relocating air that quickly.
If I was going to do something like this I think I'd put a cluster of 6 brass barrels inside a piece of 1.5" PVC and seal the area between the brass tubes. I'd use a size of brass that fits somewhat loosely on my darts (19/32" K&S in my case) so there would be negligible resistance on all barrels. Then I'd find a way to dump a LOT of air into the PVC as quickly as possible - a ball valve definitely isn't going to work here.
Interesting project, actually. You'd have a pretty accurate shotgun with a really tight spread. Of course, if I used something like that at a YANO, I'd get gang diddled for being such a bitch.

* is a ball-valve
+ is the really big pvc pipe
> is a reducer
I is an endcap
------- are hoses leading to the pvc pipes and the tire pump(make sure that they are all the same length.)
<> is the pump.
=====*---I====>---<> that is kinda what the parts would be like.
and the case like this ======(*)++++I
; (the handle)
kinda hard to think of it but it makes since to me.

My shotgun is almost finished I just need to put a handle on and spray paint it black and I'll post a pick (it looks pretty cool).

With over/under 2' brass-inside-transparent-PVC barrels, you'll be the talk of the war.
I would have built it about 2 years ago (when I first posted this) if (a) homemades were allowed in my local wars and (b) I had $100 sitting around doing nothing.
For accuracy, power, and ROF nothing beats this sucker unless you get into the realm of magazine-fed semi-auto homemade action.
