HOW TO MAKE BLACKMATCH FUSE:
|
|
Take a flat piece of plastic or metal
|
|
(brass or aluminum are easy to work
|
|
with and won't rust). Drill a 1/16th
|
|
inch hole through it. This is your die
|
|
for sizing the fuse. You can make fuses
|
|
as big as you want, but this is the
|
|
right size for the pipe bomb I will be
|
|
getting to later. To about 1/2 cup of
|
|
black powder add water to make a thin
|
|
paste. Add 1/2 teaspoon of corn starch.
|
|
Cut some one foot lengths of cotton
|
|
thread. Use cotton, not silk or thread
|
|
made from synthetic fibers. Put these
|
|
together until you have a thickness
|
|
that fills the hole in the die but can
|
|
be drawn through very easily. Tie your
|
|
bundle of threads together at one end.
|
|
Separate the threads and hold the
|
|
bundle over the black powder mixture.
|
|
Lower the threads with a circular
|
|
motion so they start curling onto the
|
|
mixture. Press them under with the back
|
|
of a teaspoon and continue lowering
|
|
them so they coil into the paste. Take
|
|
the end you are holding and thread it
|
|
through the die. Pull it through
|
|
smoothly in one long motion. To dry
|
|
your fuse, lay it on a piece of
|
|
aluminum foil and bake it in your 250
|
|
degree oven or tie it to a grill in the
|
|
oven and let it hang down. The fuse
|
|
must be baked to make it stiff enough
|
|
for the uses it will be put to later.
|
|
Air drying will not do the job. If you
|
|
used Sodium Nitrate, it will not even
|
|
dry completely at room temperatures.
|
|
Cut the dry fuse with sissors into 2
|
|
inch lengths and store in an air tight
|
|
container. Handle this fuse carefuly to
|
|
avoid breaking it. You can also use a
|
|
firecracker fuse if you have any
|
|
available. The fuses can usually be
|
|
pulled out without breaking. To give
|
|
yourself some running time, you will be
|
|
extending these fuses (blackmatch or
|
|
firecracker fuse) with sulfured wick.
|
|
|
|
|
|
HOW TO MAKE SULFURED WICK: Use heavy
|
|
cotton string about 1/8th inch in
|
|
diameter. You can find some at a garden
|
|
supply for tieing up your tomatoes. Be
|
|
sure it's cotton. You can test it by
|
|
lighting one end. It sould continue to
|
|
burn after the match is removed and
|
|
when blown out will have a smoldering
|
|
coal on the end. Put some sulfur in a
|
|
small container like a small pie pan
|
|
and melt it in the oven at 250 degrees.
|
|
It will melt into a transparent yellow
|
|
liquid. If it starts turning brown, it
|
|
is too hot. Coil about a one foot
|
|
length of string into it. The melted
|
|
sulfur will soak in quickly. When
|
|
saturated, pull it out and tie it up to
|
|
cool and harden. It can be cut to
|
|
desired lengths with sissors. 2 inches
|
|
is about right. These wicks will burn
|
|
slowly with a blue flame and do not
|
|
blow out easily in a moderate wind.
|
|
They will not burn through a hole in a
|
|
metal pipe, but are great for extending
|
|
your other fuse. They will not throw
|
|
off sparks. Blackmatch generates sparks
|
|
which can ignite it along its length
|
|
causing unpredictable burning times.
|
|
Now you have the basic ingredients to
|
|
shake the earth like thunder. In the
|
|
next installment or two, I will tell
|
|
you how to put it all together to do ju
|
|
st that. You will find that you have
|
|
baked a very deadly pie. I have twice
|
|
been accused of setting off dynamite in
|
|
the woods. The explosive power of your
|
|
little grey powder may exceed your
|
|
expectations, so choose your testing
|
|
ground with care.
