- ----------------------
-
- 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
- -----------------------------
- Put the 3 combined chemicals into a plastic refrigerator container with a very
- 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:
- 2 inch wide gummed, brown paper packaging tape
- 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):
-
- Many times the paper tape will start to run off to one side or the other. You
- 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.
- But DO NOT USE STEEL! It is for your safety.
-
- 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....
