my humble 900+ page site. Come on in,
make sure your coffee's freshly topped off. A
handy share button is found on the bottom of most
pages, or just copy the address from the
navigation bar at your page top. This
page links you to my vast toy room, and
you can be here for literally hours and
not see everything. Minigun and Browning
videos and construction plans, airsoft videos and
gun mods, and a whole lot more that's very
unexpected. Please, tell your friends

| The
killbuckets medium minigun design, also known as the Hailforce
layout
I'm getting bugged silly about making
these NOW, so...
The patterns are
available, and you really don't need a CNC. These are
intentionally simple shapes, a $14 coping saw (or better, a
$99 scroll
saw) and a drill, maybe a rat-tail file, are all you
really need.
This panel represents a chunk of 6mm ABS, 24 x
10.25(these are the machine
offsets).

Outside of the tubing parts, this is all
the parts that need to be fabbed to make one of the little
minis in the renders posted previously.
Parts List:
3
(i.d.)ABS Celcon tubing (yes, common black plastic pipe from
the hardware store):
One ea., 9
long.
One ea., 13 long.
One ea., 6 long.
1/2 (i.d.
again)PVC tubing:
Seven ea., 17.75
long.
A small
handful of #6 x 1/2 sheetmetal screws, and the 18 components
depicted above, along with a stripped Chi-Com M14, and you
have a MINI-Minigun.
It's less than
three feet long, assembled. The barrel pack is 3.5 in
diameter.
I set this up so
a 24inch repair section of 3 ABS from the hardware store could
be cut right at 13, leaving the scrap 9 long. The 13
section becomes the main body tube, the 9 becomes the drive
motor casing (this will also double as the ammo dump).
Then I just have to find a 6 section in
the shop to become the delinker.
This will actually hold the power pack,
so a longer section may be used.
...at times,
Rockstar Makes Killbucket!
This will also
need a Bissel Vac Belt to drive the barrels, and an RC car
motor.
An aluminum spacer from
McMaster-Carr .115 I.D. x 1 x3/16 O.D. rnd 4N100R18AP
will extend the motor's shaft.

Barrel drive motor
here.
On BB-feed
lines:
Hard plastic lines just didn't
work out for me. Most would stop the BB's if bent too far, and
even if not bent, had length limitations due to friction
inside the lines.
McMaster-Carr to the
rescue!
9664K49 continuous length
spring. 36 long. $3.36 each.
Need
something longer? You can connect lengths up using silicone
tubing segments.
It just so happens
that the perfect size is handily available. The nearby
Wal-Mart has replacement slings for the Wrist Rocket
slingshots, at a measly $2.25. Cut into 1 to 1-1/2 chunks,
it makes cheap, secure connectors.
The grip was a
bit bulky, but really wasn't hard on my mitts.
This is more comfy, and works really,
really nice.
You can firmly
grip the handle without activating the switches.
A bit more pressure at the points
indicated, and you can feel the buttons snap on/off
readily.
It folds flat
against the body without any worry of accidental
activation.
The pivot bolt is
adjustable for tension, and the grip can be operated in its
folded position, or anywhere up to 60degrees from the barrel
axis.
Since I have a few hundred servo
leads lying about, I pressed one into place as a handle
disconnect. The grip controls a set of relays with low
current, so the wires can be tiny with no problems.
The BB-fill port
glued in, I'll use a plastic cap as a closure, maybe fake a
motor power cable coming from it.
The front grip
will be a foam-covered tube. It's Photoshopped in for the
moment.
