- @X086@X05.@X0821 @X03BASIC PIPE CANNON
-
- @X08A simple cannon can be made from a thick pipe by almost anyone@X05. @X08 The
- only difficult part is finding a pipe that is extremely smooth on its interior@X05.
- @X08This is absolutely necessary@X05;@X08 otherwise@X05, @X08the projectile may jam@X05. @X08 Copper or
- aluminum piping is usually smooth enough@X05,@X08 but it must also be extremely thick to
- withstand the pressure developed by the expanding hot gasses in a cannon@X05.@X08 If
- one uses a projectile such as a CO2 cartridge@X05,@X08 since such a projectile can be
- made to explode@X05,@X08 a pipe that is about 1@X05.@X085 @X05-@X08 2 feet long is ideal@X05.@X08 Such a pipe
- MUST have walls that are at least 1@X05/@X083 to 1@X05/@X082 an inch thick@X05,@X08 and be very smooth
- on the interior@X05. @X08 If possible@X05,@X08 screw an endplug into the pipe@X05. @X08Otherwise@X05,@X08 the
- pipe must be crimped and folded closed@X05,@X08 without cracking or tearing the pipe@X05.@X08
- A small hole is drilled in the back of the pipe near the crimp or endplug@X05.@X08
- Then@X05,@X08 all that need be done is fill the pipe with about two teaspoons of
- grade blackpowder or pyrodex@X05,@X08 insert a fuse@X05,@X08 pack it lightly by ramming a wad
- of tissue paper down the barrel@X05,@X08 and drop in a CO2 cartridge@X05.@X08 Brace the cannon
- securely against a strong structure@X05,@X08 light the fuse@X05,@X08 and run@X05.@X08 If the person is
- lucky@X05, @X08he will not have overcharged the cannon@X05,@X08 and he will not be hit by
- pieces of exploding barrel@X05.@X08 Such a cannon would look like this@X05:

- @X08An exploding projectile can be made for this type of cannon with a CO2
- cartridge@X05.@X08 It is relatively simple to do@X05.@X08 Just make a crater maker@X05,@X08 and
- construct it such that the fuse projects about an inch from the end of the
- cartridge@X05.@X08 Then@X05,@X08 wrap the fuse with duct tape@X05,@X08 covering it entirely@X05,@X08 except for
- a small amount at the end@X05.@X08 Put this in the pipe cannon without using a tissue
- paper packing wad@X05.@X08 When the cannon is fired@X05,@X08 it will ignite the end of the fuse,
- and shoot the CO2 cartridge@X05.@X08 The explosive-filled cartridge will explode in
- about three seconds@X05,@X08 if all goes well@X05.@X08 Such a projectile would look like this@X05:
