- YOU WILL NEED:-
-
- A metal can with a press on lid. Examples are paint cans, or Hershey's Coco
- or Nestle's Quik cans. The new paper cans will work too but they wear out fast.
- A tank of acetylene or the ACETYLENE GENERATOR from the preceeding file in
- this series <FZFF03>.
-
- THE SETUP/ASSEMBLY:-
-
- Drill or poke a small hole in the middle of the bottom of the metal can
- of 1/16" or less, diameter. Drill or poke a similar hole in the middle of the
- lid of the can. Put a piece of waterproof tape (like black electricians tape)
- over the outside of each hole.
-
- USING IT:-
-
- The easiest way to safely load the "Canon" is to begin by filling it with
- water and then using it in a collection trough (Like the one shown in FZFF03;
- Acetylene Gas). The bubbler tube can be connected to an acetylene tank such
- as on a welders torch, or the Acetylene Generator or bags of acetylene filled
- with the Generator shown in FZFF03. Once the can is full of gas (after the water
- has all drained out and bubbles start coming from under-neath the inverted can,
- press on the lid, and leave the tape in place.
-
- IN PRINCIPLE:-
-
- Once you take the <NOW LOADED> "Canon" to where you want to use it, by
- setting the can on something that will keep it off the ground and is ventillated
- underneath, countdown can be started. Remove the tape from both holes. Since
- Acetylene is lighter than air, air will begin entering the bottom hole as
- acetylene floats out the top. The flow is just about right to make a lantern
- flame above the exit hole at the top. Promptly light the top hole of the can and
- and get back, deliberately, as you will have several minutes to wait. (The time
- depends on the size of the can you use and the size of the pinholes you put in
- it.)
-
- At the beginning, the can contains and vents only acetylene so that only
- above the can can it get enough air to burn, and only the gas which has exited
- is flamable. As air comes in the bottom, though, it begins to mix with the
- gas inside the can so that the mixture becomes increasingly activated with oxygen.
- Eventually the air level will reach its Flash Ratio, and the flame from the
- top of the can will move down inside, igniting all the acetylene that remains
- inside the can AT ONCE, and the "Canon" GOES OFF.
-
- FIRING PHILOSOPHIES:-
-
- Straight off you will see that you have a choice of setting off the shot
- with the lid up (to shoot the lid) or the lid down (to shoot the can) into the
- air. Also, because the fuse flame is sensitive to wind, you may want to
- fashion a chimney (or "Barrel") out of another can, a roll of linoleum or formica, or
- a length of PVC pipe of suitable diameter. This has two additional advantages
- beyond keeping the flame lighted, in that it dramatically enhances the BOOM,
- but also improves your control over the direction of the projectile ejected.
-
- By loading many canisters with their holes taped, before hand, you then
- have yourself an easy reloader, cartridge fashion.
-
- Another variation is to put the pinholes on opposite sides of the metal
- can and then mounting it in the "Barrel" horizontally. In this case, a backstop
- is needed and the chimney cannot be part of the "Barrel".
-
- Some of my best shots have been 5 gal ice cream carton or hat box One-
- Shotters, filled dry from an acetylene tank at a wide setting. Because of the
- uncertainty of this fill method, these canons were lit with sparklers on the
- end of a 12 foot pole.
-
- This kind of canon readily lends itself to loudness, altitude and
- distance competitions, since it's all hand made.
