I have built
many homemade M134 guns. I did most of the design work in 3D,
and here's the video loops to check shapes.

the killbuckets miniguns tour.

the minigun drive motor.

This homemade minigun body assembly with spinning
barrels can hold about any airsoft gearbox, but is
designed for the M249 and it's clones. a crafty
person could probably drop a mini-14 or a 10-22 ruger
into one and have a BALL. Don't try this yourself, kids!
The black disc in the middle of this
assembly is a rubber sheet. It allows minor alignment
adjustments to the barrel pack. More important, it
absorbs vibrations and allows the minigun to spin the
barrels up faster, and stop them instantly using dynamic
braking.
If you have a Home Depot, Lowe's,
Builders Square, OSH, ACE, etc nearby, you'll find every part needed except the bearings (Timken
set #3 found at all auto parts stores, std front
wheel bearing Chevy Colorado 2WD pickup application)
for the barrel pack.
This is a 1:1 CAD model I created, to
make sure the home built
m134 minigun components DO fit together...before I make any of them.
What looks
like a grenade launcher stuck onto the minigun's carry yoke is actually
the ammo bin. The little square box underneath is a
reworked RC car servo, to drive the M14
hicap.
With
a click, I can make this any color I want
to see it, in CAD. RED shows the shapes off better.
Here's a tail-end render of the make it yourself minigun body, showing the
gearbox access door opened, and the rear disc on the body
mentioned above.
Look
close, you can see the big wing knobs that hold the
yoke and front loop in
place.
The
killbuckets minigun delinker is a dummy assembly, and you can
make it as detailed or simple as you wish. In reality, it's
the most complex part of a minigun. The control handle
was designed as a simple tube, but most were built using a
Logitech Attack II Joystick.
You can also see the Kenmore (I used
to be a Sears Repairman. Really.) drive belt that spins the
barrels. Note that the silver block inside the body represents
an M249 airsoft gearbox, and an M14 airsoft gearbox unit is
shaped much differently.
