Oh, and I found some more videos for reference:
(the first one is a paintball minigun, where as the other 2 are airsoft)

If you plan on buying one, they are $800+. That's why I am making mine and also as a sort of fund raiser for spudfiles.

When it is completed, I plan on selling it and donating 50% of the profits to spudfiles :lol:

That way, I benifit and also the spudding community for there help.

Is it possible to build a paintbal vortex gun ?

I have an idea... wouldn't it be easier and cheaper to build a simple vortex gun and add fake barrels rotating just for the looks...? I understand that you want to make a 'real' minigun but hey that makes everything 10X times more difficult...

Oh sorry i didn't see the first page of this topic
I thought your above post was the topic :oops:

$800, bahh there goes ultimate ownage in airsoft.

But you are going to need a lot of excpencive machining and excpencive parts to make something like this.
Have you made a piston valve yet?
If not i would reccomend you make one for the practice, and maybe a hammer valve after that just without a rotating barrel. All for practice
Most of this might of been mentioned in the previous page but i didn't bother to read it all

but I agree with thunderlord, just do something like that.

yes, i have made a piston valve copper rifle but never posted it because it was scraped to the nearest junk yard do to a stupid mom. It was really good but I never took pics because I made it before I knew about spudfiles.

Anyway, I have plans, briliant ones, i just have yet to post them, I will do it later. As for parts, I have plenty of connections. All of this is stated on P.1.

sorry, double post...

Anyway, here's a site where this guy actually manufactures miniguns and sells them

click here


Man that P3 auto loader is wicked. I got some ideas on how to make it :idea:

EDIT: here's a pic of the disassembled hand held minigun:

Here is his patent for his miniguns. Not sure if he still makes them the same or not.
http://www.google.com/patents?id=Zz8FAAAAEBAJ

He was also the creator of the Strafer BB machine gun which was inspiration for spudsonfire's reverse engineering to create the vortex block that we use.

With two + tanks and the design being handheld weight starts to be a factor...

Sorry, I forgot he wanted a man portable weapon; I was describing a crew-serve.

Either way, IMO any air powered Gatling gun is a theme gun by using air for one thing. So trying to design the parts exactly the same as a real one really only complicates things.
For example the main reason the barrels of a mini-gun spin is to deal with heat which is really not even a factor for pneumatic autos.
Mini-guns are cool but IMO function should win over form and however it looks if it has spinning barrels and is full auto it's a "mini-gun".

True, one of the reasons the barrels spin is for cooling, it’s also done to open and close the breach and cock the hammer; which is precisely what I was having the rotation do.

If were going for function and simplicity, a chain or powered Agar gun would be more practical and offer a high rate of fire as well.

BTW Judge, cool that you're going to church tomorrow, I was planning on going with my mom just because it's mother's day. 8)

Nothin’ special, I go every Sunday; I’m one of those “bitter Americans who cling to guns and religion…” ! :D


Let me just add that, as cool as mini-guns are, their uses in the field as a man-portable weapon are limited to a terror weapon as they’d run dry fast.
One could remedy that by adding an interrupter so that for every live round there would be 3-5 blanks so you get the drone of fire, but conserve paint.
Perhaps include a selector switch to turn the interrupter on and off.

a single rotating breech would be fine, its just hard to do rotational sealing stuff that seal well, like jsr's design it works its just hard to make
