- I have to assume that the person attempting to build this has
- some experience with fabrication or machine shop knowledge.
- If you don't, please gain some experience before attempting to
- build this device. It is very dangerous if not built correctly.
- You may not get a second chance.

- Flamers: Flamers, or one shot flamers, are simply one shot flamethrowers.
- This device can, if constructed properly, can shoot a 10 ft. dia. ball of
- flame about 100 ft. The flame sticks to the target and is very destructive.
- The flamer has been made by someone very close to the author and when
- made correctly is safe to the operator.
- Because of the availibility of parts it's hard to give measurements of
- different parts but this also gives some leeway in its construction.
-
- A flamer is a hollow tube that contains an ignition system, a propellant
- charge/delayed flame ignitor and a charge of napalm. The ignition system
- which can be mechanical or electrical, is trigerred. This in turn set offs
- the propellant charge which pushes a barrier/delayed ignitor down the tube.
- The barrier pushes the the napalm out the tube towards the target. The
- ignitor comes flying out and ignites the napalm 2 or 3 ft from the tube.
- Napalm must be used. Gasoline is explosive especially when being sprayed
- from a tube. Also, with gasoline you'll find the range is decreased as the
- gasoline is a thin liquid. Napalm on the other hand is not explosive,and can
- be made into a thick jell and burns slowly. One ounce of gasoline burns for
- about 5 mins. in a small cup. An equal amount of napalm burns for about
- 17 mins. under the same circumstances. Instructions will be given for making
- napalm.
-
- Obtain a metal tube 12" long with 1/8" walls with an inside diameter of about
- 1". This tube should be seamless and made of steel,iron or aluminum.
- Thread one end of the tube for 1" to accept an endcap. Cut 2 disks of fuel-
- proof plastic the same I.D. of the metal tube and about 1/16" thick.
- Glue this disk about 1 1/2" into the threaded end of the tube. For the glue,
- use gasket cement found at auto supply stores. This is similar to a blue
- RTV cement but it is gasoline proof. Run a small fillet of gasket cement
- around the disk on the threaded tube side. Allow the glue to dry thoroughly.
- After the glue is dry, fill the tube up with napalm for 8". This will leave
- 2 1/2" of tube empty. Push the other disk down the tube until there is only
- 1/8" of airspace over the napalm. Glue the disk in place with a small fillet
- of gasket cement. Allow the glue to dry with the tube in an upright position.
- After the glue dries lay the tube down for at least 24 hrs. and see if any
- leaks develop. If the tube leaks, either repair it or try your skill again.
-
- If you have decided on electric ignition proceed as follows: Fashion an
- electric match from a small 3v. light bulb. These can be found at Radio
- Shacks and other hobbyist electronics shops. The bulbs are used to illum-
- inate meter dials and as pilot lights. If there are no wires on the bulb,
- solder on two small wires to the terminals. Use a small triangular file and
- open the end of the bulb. If you are careful, you can open up a hole in the
- glass without breaking the filament. Mix a small amount of BLACK POWDER with
- a few drops of water to make a paste. Carefully stuff the bulb with the
- paste taking care not to break the filament and set it aside to dry.
- Drill a small hole in the endcap for the wires to go through. Insert the
- wires through the hole and glue the bulb to the inside of the endcap with a
- drop of epoxy. Seal the hole and wires with more epoxy. Put about 1 1/2 tsp.
- of FFF BLACK POWDER and 5 ignition matches into the threaded end of
- the tube. Clean off the threads and screw on the endcap.
- Obtain or make a battery case for a 3v. battery supply. Mount this on the
- flamer and wire it in series with a normally open "fire" pushbutton switch
- and a normally open "safety " slide switch and the flamer.
- To use the flamer, simply point the open end of the tube towards the target.
- Close the safety switch, and push the fire button.
- This device should be tested a number of times as performance may vary de-
- pending on differences in construction. Electric ignition makes testing safe.
- The firing wires can be led out for a safe distance then connected to an
- appropriate power supply. Make sure the napalm sprays out far enough and
- that it ignites away from the flamer. Also check the flamer tube for any
- signs of overpressure such as a bulge in the tube. Another thing to consider
- is the recoil of this device. You may have to adjust the powder charge up
- or down to make it comfortable/reliable. You can also decrease the napalm
- charge up or down slightly.
- If you want to use a mechanical method of ignition, here is one method:
- Obtain a small metal tube about 1/4 I.D. and 4" long. Wind a spring to fit
- in the small tube. This spring should be about 2" long. Drill a 1/4" hole in
- the endcap and epoxy a shotgun shell primer into it. Weld or glue a small
- collar into one end of the 1/4" tube. Fashion a firing pin from a nail or a
- piece of round stock. Drill a 3/32" hole in the small tube in the end
- opposite the collar end. This hole should go through both sides of the tube.
- This hole is for a piece of 1/8" safety wire. Insert the spring into the
- tube. Put the firing pin though the spring and let it stick out of the collar
- end of the tube. Insert a safety pin through the safety hole. Finally, epoxy
- the firing tube over the primer. Let the epoxy harden. To use, pull out the
- safety wire, point the tube at the target, pull the firing pin back all the
- way and let it go. The spring propells the firing pin into the primer setting
- it off which in turn ignites the powder charge. By the way the collar holds
- the spring/firing pin in the ignitor tube. This is a rudimentary form of
- mechanical ignition but bells and whistles can be added. This can be lever
- cocking, squeeze ignition, or a standard pull trigger. Use your imagination
- and check out your sources of hardware as many variations are possible.

- IGNITION MATCHES: These are simply small flares that ignite the napalm.
- They are made as follows. Mix 5 parts Potassium nitrate, 3 parts Powdered
- Aluminum and 2 parts Sulfur. To this add FFF BLACK POWDER in a ratio of
- 1 part mix and 1/3 POWDER. All parts by weight. Add a few drops of cornstarch
- solution to this mixture and shape the paste into 1/4" balls. Let these
- dry for at least a week.

- NAPALM: Napalm is simply thickened gasoline and can be made a number of ways.
- The original napalm was a powder that was added to gasoline to thicken it.
- It is made by taking a concentrated Ivory soap solution (not detergent)
- and pouring it into a concentrated solution of ALUM (aluminum sulphate).
- A whitish precipitate will result. This is napalm. Filter out this substance.
- Dry it in the sun for a few days. If you plan to store this napalm for a
- month or more, add a few (2-3) percent of fine ground silica gel to the
- napalm. This should stretch out the storage time for up to a year. To use it
- just add it to gasoline and shake the mixture for a few minutes. Let it sit
- for about an hour and the gasoline will thicken up. Depending on how much
- napalm is added, the gasoline can be made a thin syrup or a thick gel.
- A newer method of making napalm is to dissolve polystyrene in benzene,
- toluene, xylene or the like and then add this to gasoline to thicken it.
- Napalm for use in a flamer should be made thinner than maple syrup.
