Combine these 3 substances
in the following proportions by weight:
Potassium Nitrate…….63%
Sugar……………….27%
Sulfur………………10%
(you can by this stuff at the
drug store)
Note: use a diet scale or a gun reloading scale to measure the
ingredients
What to do with the chemicals
—————————–
tight lid
(use a soft margarine container). Now be sure that the lid is on
TIGHT. Shake the container
for about three minutes. You just made the rocket
propellant! This should be a yellowish
powder…
Making the Casing(s)
——————-
Items needed:
Scotch tape
1 foot length of 1/4 inch
diameter hardwood dowel
single edged razor blade
wet sponge
Cover the
hardwood dowel with several strips of Scotch tape (layed lengthwise
onto the dowel). Now cut a
strip of gummed paper packaging tape (8 in. long)
and lay it, gummed side DOWN, on a flat
surface. Dampen all but the last inch
of the back of the tape with a wet sponge. Turn the tape
over and start at the
dampened end, start rolling it up around the Scotch-tape-covered dowel.
After
having one layer of tape around the dowel, moisten the GUMMED side of the rest
of
the tape and roll it up around the dowel as tightly as possible.
Problem(s):
can correct
it like this (example-run off to the LEFT):
Use a single edged razor blade to the
unrolled portion of the tape right next
to the roll. Start the slit at the LEFT edge of the
tape and cut across the
tape to within 1/4/ of an inch of the RIGHT edge. Once the tape has
been
partially cut, pull it to the RIGHT and correct the mistake. (Or vice-versa)
LAST STEP IN MAKING THE CASING: when done rolling a casing, hold the last edge
of the tape
against a flat surface for a few moments; then slide the casing off
the dowel and ALLOW IT TO
DRY…you can also bake the casing(s) in your kitchen
oven at 160 degrees (F) for about 30
minutes…
Making the Nozzles
——————
Items needed:
Durham’s Rock Hard Water Putty
Epoxy Glue (part A and part B)
‘Six Penny’ (3/32")
Ungalvanized finishing nails
(quantity: amount of casings made)
one length of 1/4 inch
diameter hardwood dowel
a 7/64 inch diameter drill bit
a 1/8 inch diameter drill bit
‘Six Penny’ finishing nails are about 3/32 inch in diameter. You will now make
the
core of your rocket(s). Instead of using finishing nails you may use piano
wire that have the
same diameter. You must pack the propellant down around the
finishing nails or piano wire.,
then removing it when you’re finished.
Problem(s):
The finishing nails have a
little row of grooves right near the head. This
will cause problems as you pull the finished
rockets of the nail, so piano
wire is prefered.
The nozzle is made of the putty.
To one you are first going to form a little
1/4 inch long plug of putty in one end of each
casing. You MUST only form a
1/4 inch long plug of putty otherwise…
We are now
going to tell you how to make a gauge (in case you use too much
putty or too little than
required). Cut off a six inch length of the 1/4 inch
hardwood dowel that you bought to use the
casing with. Wrap about a dozen
layers of masking tape around it so that one edge of the
masking tape is
EXACTLY 1-3/4 inches from one end of the dowel. Slide a casing over the
dowel
and run the end of it up against this edge of the tape. If you look in the
open
end of the casing, you will see a cavity exactly 1/4 of an inch deep.
Pack this cavity full of
putty (not yet).
Mix the putty with water in a small tuna can to the appproximate
consistency
of stiff bread dough. You can pack each cavity by simply pressing a wad of
putty into the end of the casing with your finger and wiping the excess of with
your thumb.
Try to avoid creating air pockets or bubbles. After your done
with this, SLOWLY remove the
dowel depth gauge. Then let it sit to dry for
a day or lay them on a cookie cheet in the oven
and heat them at 140-160
degrees (F), depending on how many you made, for an hour to an hour
and 30 min.
After the putty is hard and dry, drill a 7/64 inch diameter hole completely
through the center of each putty plug. If I were you, I would use a power
drill. But a hand
drill is okay if you are careful and patient.
Now I will show you how to make a jig to
hold the casings upright so drilling
a hole in each putty plug won’t be a tough job. Get a
thick block of wood and
drill 3/8 inch diameter holes in it and stand the casings, putty ends
UP, in
the holes in the block. Mount your 7/64 inch drill bit in your drill press,
and
start drillin’ a hole in each putty plug. Get each hole well entered, so
work CAREFULLY.
Loading the Propellant
———————-
The sugar rocket that you
are making are core-burners. To make a core-burner,
simply pack the propellant down around a
dowel or mandrel. When the mandrel
is removed, it leaves behind a hollow core. The mandrel I
used was a short
length of 3/32 inch diameter piano wire (well you can use a finishing nail
or
piano wire). The core has to be about 1-1/4 inch long. The core starts at the
inside
edge of the nozzle plug and extends to the inside edge of the forward
bulkhead plug. The
nozzle plug is 1/4 of an inch thick, so the mandrel should
be 1-1/2 inch long. To make a
mandrel, use a small hammer to pound on a six
penny finishing nail into a block of wood. Then
use a pair of wire cutters to
snip it off to a length of exactly 1-1/2 inches. If you are
using piano wire
and not finishing nails then do this:
Drill a 3/32 inch diameter
hole in the block. Roughen up one end of the wire
with sandpaper or a file and glue the
roughen end of the wire into the hole
in block with epoxy glue. When the glue is completely
hard, grind the wire
to length with a grinding wheel.
X = Quanity of
If you
made X rockets, make X mandrels on ONE block of wood (or a few blocks
if you made about 100
rockets). To use this, set each rocket casing, drilled
end DOWN, over each mandrel (you’re
ready to load them).
LOADING THE ROCKETS:
Step One
——–
To load the propellant, you must pack it down around the mandrel(s), so the
tamp that you use must have a hole drilled right in its center and deeper than
the length of
the madrel wire inside the paper casing. Here is how to make the
tamp. Cut a 4 inch length of
1/4 inch hardwood dowel, sand the ends square,
stand it upright under the drill press, and
drill a 1/8 inch diameter hole
right down the center of the dowel to a depth of 1-1/2 inches.
You can also
use a brass or aluminum rod to make a nicer tamp instead of using the dowel.
Note: If you have access to a machine
lathe, the job will be much easier…
Step Two
——–
Next, make a paper
funnel and place it over the open rocket casing, and fill it
with about 1/8 teaspoon of
sugar-based rocket propellant. Use a small stick or
wire and poke it down into casing. Remove
the funnel and insert the tamp you
made (drilled end DOWN) into the end of the casing. Pack
the propellant down
around the wire mandrel by striking the tamp with a small hammer. Repeat
this
step (3) until the tamped powder reaches the top of the mandrel. Wad up some
tissue
paper, or paper towel, and pound it in on top of the powder. This
plug keeps the epoxy glue
used to plug the front of the rocket from running
down and sticking to the madrel. Once the
tissue plug is in place, fill the
rest of the casing with epoxy glue. After it has hardened,
twist and pull
each rocket casing off of the mandrel.
Priming and
Firing
——————
Go to a gun shop and buy a can of FFFF Fine black powder.
Priming the Rocket(s)
———————
To prime or fuse one these rockets
stand it on end, nozzle-UP, and use a small
paper trough to fill the entire core hole up to
the top with the black powder
you bought. Now you must cap it. Put about a teaspoon of the
powder into a
jar and add water a few drops at a time, stirring with a stick as you go,
until
the mixture is about the consistency of toothpaste. Then you take a small dab
of
this powder paste on the tip of your finger and smear it over the nozzle
hole of the rocket
that you just fused (primed). Make sure that the hole is
completely covered. Now just set the
rocket(s) aside to allow the paste (cap)
to dry for about 30 minutes or so.
Firing the Rocket(s)
——————–
The easiest way to launch the rocket(s) is to
glue it onto a guide stick. You
can use hibachi sticks or shish kabob skewers. You can use a
drop of instant
cyanoacrylate model cement or just use white glue and masking tape to glue
on
the sticks. To ignite the rocket(s), you can use an electric igniter or just
tape a
filament of wire from a piece of coarse steel wool over the priming cap,
attach each end to an
electrical lead or alligater clips. Attach leads to a
strong battery (6-9 volts or a car
battery), and fire by closing a switch to
complete the circuit. The current will make the
steel wool wire glow red hot,
causing it to burn and ignite the priming cap…
How ’bout an Option:
A slow lift off: Prime or fuse with pyrodex or don’t fill
the core all the way
to the top with black powder. Put a little in….
