Pipe Guns
This particular blueprint for fun has been bouncing around the Net quite freely, and I
don’t know its origin, so if you’re a copyright lawyer with an axe to grind, play nice
Commonly known as "zip" guns, guns made from pipe have been used for years by
juvenile punks. Today's Militants make them just for the hell of it or to shoot once in
an assassination or riot and throw away if there is any danger of apprehension.
They can be used many times but with some, a length of dowel is needed to force out
the spent shell.
There are many variations but the illustration shows the basic design.
First, a wooden stock is made and a groove is cut for the barrel to rest in. The barrel is
then taped securely to the stock with a good, strong tape.
The barrel is a short length of one-quarter inch steel gas or water pipe, threaded on
one or both ends, with a bore that fits in a cartridge, yet keeps the cartridge rim from
passing through the pipe. When purchasing the pipe, you should buy a cap to fit (it
should screw on the threaded end.)
The trigger is made from galvanized tin. A slot is punched in the trigger flap to hold a
roofing nail, which is wired or soldered onto the flap. The trigger is bent and nailed to
the stock on both sides. A rubber band or springs, running from the trigger to the
stock, will provide the force to detonate the cartridge primer.
The cartridge is put in the pipe and the cap, with a hole drilled through it, is screwed
on. Then the trigger is slowly released to let the nail pass through the hole and rest on
the primer.
To fire, the trigger is pulled back with the left hand and held back with the thumb of
the right hand. The gun is then aimed and the thumb releases the trigger and the thing
actually fires.
Pipes of different lengths and diameters are found in any hardware store. All caliber
bullets, from the .22 to the .45 are used in such guns.
Vicious Interlude: From another source, and for the sake of making life just a
wee bit easier, I offer the following information on pipe selection.
Caliber Pipe type and size

.22 Standard/Schedule 40, 1/8"

Standard/Schedule 40, 1/4"

.38, .357 magnum
(drill with a 25/64" bit to fit casing)

.44 special, .44 magnum

Standard/Schedule 40, 3/8"
.45 auto rim, .45 colt

12 gauge shotgun Standard/Schedule 40, 3/4"

Some zip guns are made from two or three pipes nested within each other. For
instance, a .22 shell will fit snugly into a length of a car's copper gas line.
Unfortunatey, the copper is too weak to withstand the pressure of the firing. So the
length of gas line is spread with glue and pushed into a wider length of pipe. This is
spread with glue and pushed into a length of steel pipe with threads and a cap.
Using this method, you can accomodate any cartridge, even a rifle shell. The first size
of pipe for a rifle shell accomodates the bullet. The second accomodates its wider
powder chamber.
A 12-gauge shotgun can be made from a 3/4 inch steel pipe. If you want to comply
with the gun laws, the barrel should be at least eighteen inches long.
Its firing mechanism is the same as that for the pistol. It naturally has a longer stock
and its handle is lengthened into a rifle butt. Also, a small nail is driven half way into
each side of the stock about four inches in the front of the trigger. The rubber band is
put over one nail and brought around the trigger and snagged over the other nail.
In case you actually make a zip gun, you should test it before firing it by hand. This is
done by first tying the gun to a tree or post, pointed to where it will do no damage.
Then a string is tied to the trigger and you go off several yards. The string is then
pulled back and let go. If the barrel does not blow up, the gun is safe to fire by hand.
You should not attempt to register such a gun.
