Tamping
|
|
-------
|
|
|
|
Tamping is nothing more than an operation performed before the
|
|
explosion, to regulate and direct the destructive power of the explosion. In
|
|
other words, if a pound of black powder is ignited with a match, the explosion
|
|
will occur but most of the destructive force will take the path of the least
|
|
resistance - into the atmosphere. Now, if the same pound of black powder was
|
|
placed within a steel pipe, and sealed at both ends, except for a tiny hole
|
|
for the fuse, the explosion could be regulated with ease. This tamping
|
|
operation is necessary for any forms of demolitions in order that the
|
|
operation be successful. A stick of dynamite placed on a concrete roadway
|
|
untamped, when exploded will create a very small crater, perhaps a few inches.
|
|
If this same stick of dynamite were tamped, by placing several sandbags on
|
|
top of if and around it, the explosion would create a much greater crater.
|
|
This tamping operation is absolutely necessary for the demolition of a large
|
|
structure or building.

[1> When attempting to sever a steel rod or pole, through the use of
|
|
explosives, place a charge on each side, leaving a small gap between the butts
|
|
of the explosives.
|
|
[2> When cutting a chain, place the explosive charge on one side and tape it
|
|
securely into place.
|
|
[3> When cutting any odd-shaped object, the best explosive to use is plastique
|
|
because of its flexibility. It is especially usefull and effective when
|
|
cutting heavy metal cables. The compound should be placed around the side of
|
|
the cable that is to be cut, about a half-inch thick.
|
|
When sabotaging railroad tracks with explosive, use plastique if
|
|
available, since this is the easiest substance to use when trying to sever
|
|
objects or irregular shapes. The most common way of cutting train tracks is by
|
|
placing a charge of high explosives on either side of the "I" beam track, so
|
|
as to have the forces of the two explosions act upon each other, thus causing
|
|
the middle object maximum destruction.
|
|
Another method which has proven equally effective is placing a charge
|
|
between the rail and the switch. The switch is one of the weakest points along
|
|
the line, and a relatively small charge will not only sever the switch and
|
|
rail, but will also rip up the ties and the railroad bed. Tamping with
|
|
sandbags can and should be used if at all possible, since the extent of the
|
|
damage is multiplied several times by the addition of the sandbags. Tamping
|
|
can be useless if you are on a silent lightning-fast mission. In this case,
|
|
a two-pound charge of TNT carefully placed between the switch and rail will
|
|
almost certainly do the trick without tamping. The best procedure when
|
|
engaged in this type of sabotage is to repeat the acts every three-quarters
|
|
of a mile or so, so as to delay the repairmen and create confusion.
