         PIPE OR “ZIP” GUNS

             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 trigger is made from galvanized tin.  A slot is
         punched in the trigger flap to hold a roofing, which is
         wired or soldered onto the flap. The trigger is bent and
         nailed to the stock on both sides.

             The pipe is a short length of one-quarter inch steel gas
         or water pipe with a bore that fits in a cartridge, yet
         keeps the cartridge rim from passing through the pipe.

             The cartridge is put in the pipe and the cap, with a
         hole bored 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.

             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

             You should not attempt to register such a gun.

We have a couple of threads relating to pen guns on the go.If you have something useful to add, add it to an existing relevent thread instead of starting a new one.These “plans” are all over the internet and are in the various ACs so we all came across this at one time or another.This thread is now locked.
