How
to make a Pipe Bomb
Pipe bombs
are are an issue that has been over discussed on the internet without
the involvement of any effective solid information on how to make a pipe
bomb. The information out there is usually very shallow and does not show
any real insight into the subject. This article was written with the backing
of special forces improvised munitions knowledge.
First a word
of warning. Explosives are extremely dangerous devices, forget what you've
seen in the movies, if you venture into improvised explosives manufacture
the chances are that you will lose your hands and other parts of your
body no matter how good you think you are. Life is not a thing to waste
on a pipe bomb. Having said that this article is for information purposes
only and should not be attempted.
Introduction
to Pipe Bombs
Pipe bombs are used as an alternative or to aid the use of conventional
explosives. The components of a pipe bomb are very easily available and
assembled. Additionally they can be used as a casing for high explosives
such as TNT so as to improve the capability of the explosive device. Roughly
speaking an explosive filler is placed inside a closed metal pipe and
is detonated by fuse running into the pipe, the pressure of the explosive
material when ignited builds up very rapidly and the pipe ruptures with
great force causing damage. The main components of a pipe bomb assembly
are the fuse, pipe assembly and the explosive chemicals used.
The explosive
material
The first step to improvising a pipe bomb is to choose an appropriate
explosive material as the filler. For simpler purposes match heads or
gunpowder can be used though they burn rather slowly and great a lesser
rupturing velocity of the pipe than other materials. Permanganate with
sugar half half or similarly Chlorate with sugar are easily available
materials with the chlorate having a higher explosive effect than the
permanganate. Aluminium is a potent fuel and when combined with Carbon
Tetrachloride or Permanganate can produce more dangerous explosive filler.
These are all of the lesser explosives which however are easier to acquire.
A more complicated scenario would involve the use of TNT of plastic explosives
as filler which also increases the risk factors involved. The lesser powders
are usually ground fine to accelerate their burning rate.
The Fuse
Military detonation cord is best to use as a fuse otherwise cannon or
fireworks fuses can be used instead. To make a completely improvised fuse
a tape sticky side up can be placed on a surface and sprinkled with ground
gunpowder, the powder will stick to the tape and so is a fuse although
less reliable than others. It is important to know where to place the
fuse in the assembled pipe which is discussed later in the assembly section.
Electrical detonation can also be facilitated.
Assembly
of the pipe bomb
This consists of a pipe body threaded at both ends and capped on both
ends with steel or brass caps containing the filler. The threading should
be of the coarse type as fine threading does not resist the buildup of
pressure as coarse threading does. For additional resistance a metal strip
can be wrapped from one end cap to another so as to prevent the caps from
flying off the pipe during the explosion. It is highly advised that an
inner soft lining of plastic is used in the pipe to prevent any possible
accidents with friction as when the pipe bomb is moved from place to place.
The fuse is best placed through a tiny hole drilled on one end through
a cap when both sides of the pipe are closed. However if high explosves
are used as filler one end is usually left open with the fuse placed in
the open end, if the fuse is placed erroneously in the capped end in this
case the explosive material will be blasted out of the pipe prematurely.
A thick metal pipe would create better fragmentation destruction than
a thinly walled one. During the assembly process the important fact to
consider is that explosive filler is usually sensitive to friction, so
it is important to fill the pipe carefully and avoid having powder between
the screw cap and screw threads as the friction could set them off.
