Feasibility Question - Multi-barrelled Springer
Posted 14 March 2008 - 09:43 AM
I have found an interesting PVC fitting at www.flexpvc.com. Check it out here:
The third row items are what I am talking about - the "6 port distributors".
My question is, would it be possible to build a plunger behind this thing in 2" pvc, that would keep the whole assembly short enough to fit in the bipod area of a Longshot, and would provide enough power to push darts out of all 6 barrels - or would this just be a waste of time?
I don't want to go with an air-gun for this particular deal, because I don't need long ranges and I want to be able to quickly reload and fire. I'm just not familiar enough with plungers to know if they would provide enough oomph to make this worthwhile. Ideally, I would love to load 2-3 nanos per barrel and fire off a large burst of foam with a 10'-15' range.
Any advice or outright denouncing of this idea (from those who know enough to tell me why it won't work) would be greatly appreciated.

If so, I would prefer not to go that route. I'd like to have something that would be ready to set-off at a moment's notice, just a flick of a switch or button to trigger the full burst. If it can be done that way, that is what I'd like to do.
If that's not what you mean, could you please explain in slightly more detail?

2" PVC has a good fit with 1.25" endcaps. That's the combination I used to make the "Big SNAP", which would definitely have enough air output for your purposes.

O plunger head
i i plunger rod(s)

Don't want to shove balls in tight spaces. Trust me, bad idea.

You can do some basic calculations to see if you have enough volume and space. Calculate the total volume of your barrels. Speaking in generalities, your plunger should have roughly four times that volume. Boltsniper figured that ratio when he was building the FAR; you want less range, but have more barrels, so that ratio will probably work for you.

I am not sure if this would work, but you could give it a try. The bad thing would be that the plunger rod would protrude from the front, thus making it possibly breakable.
EDIT: Pictures resized. Also, I realized I forgot to put the catch mech and trigger in, so I guess you'll have to just "imagine" it in.

We're located in I-Don't-Give-a-Damn County, in scenic Shut-the-Hell-Up-achussets.
Maybe you're familiar with our annual charity drive where we ask for shit, and no one gives any.

If that doesn't make sense, I can do up a better image later.

That method works...it's what I did on the SNAP-2. If you're using 2" PVC, you'll still need some manner of guiderod...your spring will wiggle all over the place.
I'm trying to think of a solution where there wouldn't even be a plunger rod. What I'm thinking is that the slide would be attached to the rear of the plunger head by a small rod that would go through the plunger head from side to side, and stick out through the sides of the plunger tube to be gripped by the slide as it moves back. If the plunger head is long enough, the O-ring could seat just ahead of the grooves that would be cut for the two ends of this rod, so that no air is lost. Then the spring would fit behind the plunger head and go to the rear of the tube (not far behind where the plunger head's rear comes back to).
And you're not kidding when you say the plunger head needs to be long enough...mine was something on the order of 7" long.

How come no one ever intends to create a pun? Whenever I make a pun it is always intended. There's nothing wrong with puns.

I want to make a Bigger Salvo, but cleaner looking.
EDIT: nevermind I searched "two port" and found this
