Would this Work? It should....yeah..its a Minigun

[Jeff Torres]

Yeah, It's misleading. But I'm not shooting for the actual minigun operation..but this will be hidden within the spinning Barrels, in the center.
The BB's will be shooting from the center and the Barrels are only for Ascetic purposes.

works off this idea..only I think I'll use a CO2 cartridge for portability

For all the electric Madness...I defer to you Electricians..I think with Gears and whatnot, not electricity

what do you guys think?

I'm also a noob here, but I've searched for similar devices on this site...I'm not new to the drill.


EDIT: Also I'm not shooting for accuracy...just for what a minigun is used for....Covering fire and defensive tactics

[Seagreen]

How will you regulate the velocity of the BB's. With CO2 being pressurized at 800psi and 105psi for a .2 bb to move 500fps or so...that could be an issue unless you have a regulator in-between.

[Jeff Torres]

ah...a regulator. What is that Exactly? Obviously it Regulates, is it a spring based valve that has a spring that is tested to a predetermined psi, then when it hits that critical PSI then it pops? Releasing the air, but a constant pressure would render the valve useless, As it would just hold the valve open constanly, or it would pop like a machine gun?
Or is it something completely different?

Also whilst doing some more followup research, I came across a similar design called A Vortex Gun...and upon thinking about it. That seems like a more reliable system...as well as intimating.

I know I'm skirting the edges of airsoft Legality here but..I know a couple of you guys are wanting one of these to mess with the guys casually, outside of the field.
And you can make one out of Bondo!

I have access to a machine shop, mills, lathes, CNC's, lots of Metal and a mindset to make this!
Thus making the vortex assembly much more durable...and as well as...hmmm...mass production.....

Yeah you are gonna need a regulator and hop up unit or something to feed the bbs into so they all dont just fall out the barrel. A regulator is basically a tube filled with tiny metal bbs so there are very small gaps in between and only a certain amount of gas can get through at a time. You are going to need more than one of those tiny co2 cartridges, probably a paintball co2 or compressed air tank. Then you need a firing mechanism, you can take the gas release system, trigger, bolt, and whatnot out of a cheap paintball gun. And then if you want it to actually look like something you will need to make some pretty involved body pieces. This is a huge project.

[Jeff Torres]

I should use a regulator where? Between the Gas Supply (GS) and the Electric Valve or after the valve? I assume after the GS, but please clarify.

As for the Firing Mechanism, it is simple, the GS and a valve...I'm not getting too crazy with all the mechanisms and whatnot. This is not supposed to be a elegant looking gun. the force of the GS in the Vortex Valve should provide me with the RPM's, and with an old Barrel I cannibalized from a m4 springer piece-of-crap i should get some semblance of accuracy...this is not exactly a long distance weapon...medium to short range...if that.

And so it won't imitate the Vortex Guns from the Videos, which spray out bbs manically, the Electric Feed Magazine will have a gear ratio to feed bbs to the tube at a pace that is not ridiculous, but enough to warrant a mini gun.

[Pope_Alex_Kaeda_I]

Im just going to put this out there. Do with it as you will . . . . . if you dont know how to use a regulator, your engineering skills are probably not up to par to do this project. Asking the rest of us to fix your engineering . . . . thats like asking a bunch of midgets to play for the Detroit Tigers in the Superbowl. They might show up, but thats a upsidedown up left handed football bat they're going to swing.

No, no, no I'm not trying to have you guys fix my Idea or force it down your thoats, or anything. I'm just asking what Would you do. Some advice I will take and use (the regulator) and other things I would discard after Consideration.

I'm not a actual Engineer, but I do have a firm understanding of how things work...mechanically atleast. I like to take apart things, and look at them, think of how I can improve them whilst simplifying them. I guess I'm just a Tinkerer.

This is my first forray into airsoft modding...or Building I guess, and so any and all Suggestions are welcome!

[chapped]

I think you're in over your head.

[Jester316]

If you don't know what a regulator is/does and don't know where to incorporate it into your design, you need to stop messing with things that could kill you.

[Falcon7]

Yes, the regulator would go after the gas source to get it down to a manageable psi. If you don't have some kind of firing mechanism to control gas release, and just a open/closed valve, all your gas is going to leak out pretty quickly. Also, you might have trouble getting the psi low enough for it to be safe. The regulators used to fill helium balloons would work, I have one laying around if you want it. Btw, do some fancy math, or have someone do it for you, to figure out the proper psi to propel whatever weight bb you use and the proper speed.

[Jeff Torres]

I think you're in over your head.

Yeah, it may seem a little confusing to others...Maybe I'm not explaining it enough. It works fine in my head (haha, like that ever proved anything)

Right.

The GS is connected to the valve
The Valve is connected to the regulator.
The Regulator is connected to the Vortex Block
The Vortex Block has 2 holes, one for Air, and another for the Barrel.

When the Valve is opened, the gas encounters the regulator, which brings it down to the required PSI.
Then the Gas Enters the Vortex Block, which Interacts with the feeding system (simple enough) and spins the bb's around (thus eliminating any jamming)
and eventually the bbs will find the barrel and exit...propelled by the gas

The feed is regulated by the feeding system gear ratio...perhaps 2:1?

In theory it should work. I'll get to work drawing up plans so I can get this thing into My Machine shop.

[RiotingCows]

You might just want to get an m4 body, gas internals, and hook up a box mag for your ammo issue and work from there and then all you have to deal with is the regulation of co2 tank and how it looks

[Jeff Torres]

Much like this Gentleman?

[Falcon7]

Ah, you never mentioned the vortex block. It isn't the most efficient method, especially with a limited air supply. If you really want this to work in game, I recommend using the aforementioned gas blow-back system.

[glockmeister]

dude that video of it looked pretty cool. Make one.
