INSTRUCTIONS FOR MAKING .44 REMINGTON MAGNUM-SIZED BOMBS
|
||
|
|
||
|
The following instructions will lead you through the steps necessary to
|
||
|
manufacture small pyrotechnic devices. These devices are NOT TOYS, and
|
||
|
are EXTREMELY DANGEROUS to manufacture and use.
|
||
|
|
||
|
Furthermore, there are many laws on the books at both the Federal and
|
||
|
State levels which make the manufacture of such devices a FELONY, and many
|
||
|
laws also cover the INTENT to manufacture these devices, making that a
|
||
|
FELONY as well.
|
||
|
|
||
|
Therefore, this material is presented only to show you what is possible
|
||
|
with a few simple materials and a little bit of time. DO NOT ACTUALLY
|
||
|
MAKE ANY OF THESE DEVICES! That being said, let's get down to the brass
|
||
|
tacks of what's involved here. First a few lists:
|
||
|
|
||
|
Tools/Containers:
|
||
|
hot glue gun (around $10-$15 at any hardware store)
|
||
|
powder measure (calibrated for black powder by volume)
|
||
|
powder funnel (to load the powder measure)
|
||
|
wire cutters or scissors (wire cutters work best)
|
||
|
machine shop goggles (wrap-around type)
|
||
|
ceramic coffee cup (very clean, and very dry)
|
||
|
|
||
|
Materials/Supplies:
|
||
|
.44 Remington Magnum brass (spent primer still in place)
|
||
|
Pyrodex P powder (black powder is NOT recommended!)
|
||
|
hot glue sticks
|
||
|
green cannon hobby fuze
|
||
|
3x5 index card (for hot glue testing)
|
||
|
paint or spray paint (optional)
|
||
|
|
||
|
SETUP AND PREPARATION
|
||
|
|
||
|
Put your safety glasses on. Never handle any explosives or explosive
|
||
|
components without first protecting your eyes. Modern machine-shop-
|
||
|
quality goggles have amazing protective capabilities when used properly,
|
||
|
and I would not be able to read this screen today had I not regularly worn
|
||
|
these things while messing with explosives. It's also nice to have fresh,
|
||
|
clean, clear (unsmoked) goggles. It lets you really see what you are
|
||
|
doing easily.
|
||
|
|
||
|
Extinguish any cigarettes or other open flames (candles, stove) before
|
||
|
proceeding any further. This is REALLY important!
|
||
|
|
||
|
Lay out a clean work area, covered with sheets of newspaper or something
|
||
|
else (such as an old sheet) to protect the surface you're working on.
|
||
|
|
||
|
Plug in the hot glue gun, and place it somewhere safe while it warms up.
|
||
|
|
||
|
If the brass casings you have do NOT have primers installed, it will be
|
||
|
necessary for you to first squirt a small droplet of hot glue into the
|
||
|
hole where the primer normally seats. Make sure the primer hole is
|
||
|
completely sealed so that no powder can spill out, and so that the devices
|
||
|
remain water-tight.
|
||
|
|
||
|
The brass cases should be reasonably clean. Leftover powder residue (from
|
||
|
their normal firing in a gun) is usually not a problem, but excessive
|
||
|
contaminants such as gun grease or dirt may adversely affect the quality
|
||
|
of the product you are making.
|
||
|
|
||
|
Pour approximately 1/4 cup of gun powder into the coffee cup [this is
|
||
|
enough to make a lot of these little devices!], and put away the rest of
|
||
|
the powder, closing the cap and storing it away from your work area. Keep
|
||
|
the amount of exposed powder you have lying around as small as possible,
|
||
|
in case of any kind of accidental ignition.
|
||
|
|
||
|
INITIAL TESTING AND ADJUSTMENT (VERY IMPORTANT!)
|
||
|
|
||
|
To ensure that your hot glue gun is not too hot for the powder you are
|
||
|
using, take a small amount of powder (about a pinch of it or so) and put
|
||
|
it in a small pile on an index card in the middle of your work area.
|
||
|
Temporarily put away the coffee cup of extra powder, just in case the glue
|
||
|
gun sets off the small pile of powder. When the glue gun has reached full
|
||
|
operating temperature (approximately 10-15 minutes), place the hot nozzle
|
||
|
against the powder and hold it for a full minute or two. If nothing
|
||
|
happens, carefully squirt a blob of the hot glue onto the small pile of
|
||
|
powder. Using the back of a metal spoon, press the melted hot glue firmly
|
||
|
into the powder until you hear individual grains of powder crunching and
|
||
|
mixing with the glue. As long as there is no ignition (I have never seen
|
||
|
Pyrodex ignite like this, but black powder might be prone to such
|
||
|
detonation), then the glue gun is safe to use. Wait until the glue on the
|
||
|
spoon cools, then just scrape the blob off with a knife, flushing it down
|
||
|
the toilet or otherwise wetting it before disposal.
|
||
|
|
||
|
To adjust your powder load, set the powder measure to approximately 20-22
|
||
|
grains (by volume in a CVA powder measure), and load a single casing with
|
||
|
powder. The case should be approximately 65-70% full. Any more powder
|
||
|
than this causes the explosive force DECREASE, as you cannot seal the
|
||
|
casing as effectively. Adjust the setting on the powder measure to obtain
|
||
|
this approximate 65-70% fill capacity for the cases you are using. I find
|
||
|
that the dotted crimp around the case that marks the seating point for the
|
||
|
bullet is a good level to fill to. When you have adjusted your measure to
|
||
|
the desired fill level, lock down the measure set screw, and pour all the
|
||
|
powder back into the coffee cup.
|
||
|
|
||
|
When you have your powder setting adjusted properly, the glue gun is warm,
|
||
|
and your work area is clean and neat, it's time to begin production.
|
||
|
|
||
|
PRODUCTION
|
||
|
|
||
|
Lay out five (5) brass cases, base down, open end up. Using the wire
|
||
|
cutters, snip off five (5) sections of fuze wire approximately 4" long.
|
||
|
I work on five cases at a time, because it gives me the best rate of speed
|
||
|
and keeps the clutter to a minimum on my work area. If you feel unsure or
|
||
|
unhandy with any of this, start with working on a single casing at a time
|
||
|
first, then work up to "mass production."
|
||
|
|
||
|
Load each of the cases with the measured powder charge, setting them
|
||
|
carefully back down so as not to spill powder. Set the cases down far
|
||
|
enough apart that you can pick each one up individually without fear of
|
||
|
knocking the others over.
|
||
|
|
||
|
One at a time you will now fuze and seal the casings. This is the most
|
||
|
critical and technique-oriented part of the procedure. You want to have
|
||
|
a good solid glue plug installed, plus the fuze must reach all the way
|
||
|
through the glue plug and make solid contact with the charge. Experiment
|
||
|
with your technique, and come out with whatever method results in the most
|
||
|
consistent loads for you. This is how I do it:
|
||
|
|
||
|
Put one end of a section of fuze firmly into the powder. Press it into
|
||
|
the powder at least 1/4 of an inch, or even all the way through the powder
|
||
|
until it bumps against the base of the casing.
|
||
|
|
||
|
Put the nozzle of the glue gun into the open end of the case, pushing the
|
||
|
fuze aside gently. Slowly squirt molten glue into the casing, and begin
|
||
|
slowly turning the case in your fingers, pushing the fuze around as you
|
||
|
spread the glue evenly onto the loose powder around the fuze. Do not
|
||
|
twirl the case so fast that you drag a glue blob around, because this will
|
||
|
disturb the powder charge.
|
||
|
|
||
|
As the case fills with molten glue, retract the nozzle and continue
|
||
|
rotating the case and filling it until it is slightly more than full. The
|
||
|
amount of extra glue can be experimented with, and will typically be
|
||
|
sucked back into the case as you do the next step.
|
||
|
|
||
|
Put the glue gun down. Holding the case in one hand and the fuze in the
|
||
|
other, slowly twist the fuze in circles, swirling the still-melted glue
|
||
|
around and allowing it to settle down against the powder. Do not pull on
|
||
|
the fuze! Keep the fuze pressed firmly into the powder as you twist it.
|
||
|
This procedure also "burps" the case, bringing any extra air that might
|
||
|
have got trapped between the glue and the powder up to the surface.
|
||
|
Within a few twists you may see a bubble appear. Keep twisting and
|
||
|
pressing in the fuze until this bubble surfaces and pops. This is where
|
||
|
the extra glue comes in. You may need to add another tiny blob of glue to
|
||
|
bring the top of the glue to the level of the case rim.
|
||
|
|
||
|
As each case is completed, set it aside to cool. Placing the cases in
|
||
|
front of a desk fan (don't put a fan anywhere near where you're handling
|
||
|
loose powder!) helps the cooling process significantly.
|
||
|
|
||
|
FINAL PRODUCTION
|
||
|
|
||
|
When you have made all the devices and they have had a chance to COOL
|
||
|
COMPLETELY, you may proceed to the painting stage, or skip over it
|
||
|
entirely, at your discretion. Painting the devices only makes them look
|
||
|
a lot cooler, not to mention giving them a less sinister appearance than
|
||
|
a bunch of brass cases with fuzes sticking out of them!
|
||
|
|
||
|
My preferred method of painting is to dip each device into thick one-coat
|
||
|
enamel paint, usually white or light gray, and then set them out on a
|
||
|
foil-covered plastic fast-food tray. Wait for one hour for the paint to
|
||
|
get slightly tacky and the excess to run off and pool up around each
|
||
|
device. After an hour or so, transfer each device to another foil-coated
|
||
|
tray, where they will finish their drying. At this point, I like to take
|
||
|
various colored spraypaints and spatter the devices randomly with colors.
|
||
|
The more brighter and cheerier the colors, the less threatening the
|
||
|
devices will appear to a casual bystander.
|
||
|
|
||
|
But on the other hand, you might take it in mind to paint them all bright
|
||
|
firecracker red, just so you know exactly what they are! Have fun with
|
||
|
it.
|
||
|
|
||
|
CLEANUP
|
||
|
|
||
|
Put away unused powder from the coffee cup only. Mop up any spilled
|
||
|
powder with a wet paper towel -- DO NOT USE A VACUUM CLEANER! THEY HAVE
|
||
|
ELECTRIC MOTORS WHICH MAKE SPARKS!
|
||
|
|
||
|
IGNITION AND USE
|
||
|
|
||
|
These little devices (and they really are quite small when you see what
|
||
|
they end up being able to do!) are a load of fun to have around on camping
|
||
|
trips, 4th of July and New Years holidays, boating trips, and for general
|
||
|
pranking around.
|
||
|
|
||
|
HOWEVER, REMEMBER THAT SINCE THE CASES ARE MADE OF METAL (BRASS), THEY
|
||
|
WILL FLY OFF AT SPEEDS SUFFICIENT TO CAUSE BODILY INJURY OR DEATH. DON'T
|
||
|
TRY AND HOLD ONE OF THESE THINGS IN YOUR HAND WHEN YOU LIGHT IT! ALWAYS
|
||
|
MAKE SURE YOU ARE CLEAR OF THE AREA AND HIDING BEHIND SOMETHING SOLID
|
||
|
BEFORE THE DEVICE GOES OFF!
|
||
|
|
||
|
An interesting feature of these devices [if they are made properly and you
|
||
|
employ good-quality waterproof green fuze wire] is that they may be tossed
|
||
|
into water after they have been lit. You can try this out in your
|
||
|
swimming pool, or even in the ocean. Just make sure the core of the fuze
|
||
|
is properly burning [you can tell this by the sparkling that happens when
|
||
|
the core burns], and fling the device into the water. It makes a very
|
||
|
impressive "THUMP!" sound. If the water is shallow enough (just a few
|
||
|
inches), you may even get a plume of water spraying into the air.
|
||
|
Throwing these devices into a deep swimming pool and then standing next to
|
||
|
it and watching them go off is probably the SAFEST way to set them off and
|
||
|
actually watch them in action.
|
||
|
|
||
|
SAFETY CONSIDERATIONS
|
||
|
|
||
|
Know that you are working here with METAL-CASED explosives, and when metal
|
||
|
cases fragment and fly off, even small particles can do considerable harm.
|
||
|
The entire base of the .44 Remington Magnum cartridge is almost guaranteed
|
||
|
to remain intact, and upon detonation will eject "backwards" with
|
||
|
velocities approaching that of some handgun rounds. It can break glass,
|
||
|
go through pieces of wood, go through clothing, rip open skin, etc. It
|
||
|
can also ricochet off of hard surfaces and continue with a redirected path
|
||
|
of destruction.
|
||
|
|
||
|
For safe noisemaking fun (like around the 4th of July), these devices are
|
||
|
best if the entire case is buried, so that the top of the case is just a
|
||
|
little ways under the ground. If you grip the upper part of the case
|
||
|
(where the fuze comes out) and press it firmly into soft soil, or bury it
|
||
|
in sand, this tends to contain the shrapnel. No guarantees, however,
|
||
|
since sometimes, depending on how good the glue seal was, the top part of
|
||
|
the device (the brass and the glue plug) blows off and flies off very
|
||
|
rapidly. DO NOT get in the way of this sort of thing!
|
||
|
|
||
|
While this is not a particularly RECOMMENDED practice as far as safety
|
||
|
goes, one can also launch these devices from a slingshot. Put the device
|
||
|
into the pouch, then either light it yourself (difficult), or ask a friend
|
||
|
to light it. As soon as the fuze catches, fire the slingshot and send it
|
||
|
flying. If you wait and time the fuze just right, you can have it burst
|
||
|
high up in the air, which causes a far more significant sound "footprint"
|
||
|
(i.e., more people hear it).
