- @X084@X05.@X0821 @X03 FUSE IGNITION
-
- @X08The oldest form of explosive ignition@X05,@X08 fuses are perhaps the favorite
- type of simple ignition system@X05.@X08 By simply placing a piece of waterproof fuse in
- a device@X05,@X08 one can have almost guaranteed ignition@X05.@X08 Modern waterproof fuse is
- extremely reliable@X05,@X08 burning at a rate of about 2@X05.@X085 seconds to the inch@X05.@X08 It is
- available as model rocketry fuse in most hobby shops@X05,@X08 and costs about $3@X05.@X0800 for
- a nine@X05-@X08foot length@X05.@X08 Fuse is a popular ignition system for pipe bombers because
- of its simplicity@X05.@X08 All that need be done is light it with a match or lighter@X05.@X08
-
- Of course@X05,@X08 if the Army had fuses like this@X05,@X08 then the grenade@X05,@X08 which uses
- fuse ignition@X05,@X08 would be very impracticle@X05.@X08 If a grenade ignition system can be
- acquired@X05,@X08 by all means@X05,@X08 it is the most effective@X05.@X08 But@X05,@X08 since such things do not
- just float around@X05,@X08 the next best thing is to prepare a fuse system which does
- not require the use of a match or lighter@X05,@X08 but still retains its simplicity@X05.@X08
- One such method is described below@X05:@X08
-
- MATERIALS
- @X05_________
-
- @X08strike@X05-@X08on@X05-@X08cover type matches
-
- electrical tape or duct tape
-
- waterproof fuse
-
-
- 1@X05)@X08 To determine the burn rate of a particular type of fuse@X05,@X08 simply measure a
- 6 inch or longer piece of fuse and ignite it@X05.@X08 With a stopwatch@X05,@X08 press the
- start button the at the instant when the fuse lights@X05,@X08 and stop the watch when
- the fuse reaches its end@X05.@X08 Divide the time of burn by the length of fuse@X05,@X08 and
- you have the burn rate of the fuse@X05,@X08 in seconds per inch@X05.@X08 This will be shown
- below@X05:@X08
-
- Suppose an eight inch piece of fuse is burned@X05,@X08 and its complete time
- of combustion is 20 seconds@X05.@X08
-
- 20 seconds
- @X05__________ @X05=@X08 2@X05.@X085 seconds per inch@X05.@X08
- 8 inches
-
- If a delay of 10 seconds was desired with this fuse@X05,@X08 divide the desired
- time by the number of seconds per inch@X05:@X08
-
- 10 seconds
- @X05___________________ @X05=@X08 4 inches
- 2@X05.@X085 seconds @X05/@X08 inch
-
-
- NOTE@X05:@X08 THE LENGTH OF FUSE HERE MEANS LENGTH OF FUSE TO THE POWDER@X05.@X08 SOME FUSE@X05,@X08
- AT LEAST AN INCH@X05,@X08 SHOULD BE INSIDE THE DEVICE@X05.@X08 ALWAYS ADD THIS EXTRA
- INCH@X05,@X08 AND PUT THIS EXTRA INCH AN INCH INTO THE DEVICE@X05!@X08@X05!@X08@X05!@X08
-
- 2@X05)@X08 After deciding how long a delay is desired before the explosive device is
- to go off@X05,@X08 add about 1@X05/@X082 an inch to the premeasured amount of fuse@X05,@X08 and
- cut it off@X05.@X08
-
- 3@X05)@X08 Carefully remove the cardboard matches from the paper match case@X05.@X08 Do not
- pull off individual matches@X05;@X08 keep all the matches attached to the cardboard
- base@X05.@X08 Take one of the cardboard match sections@X05,@X08 and leave the other one
- to make a second igniter@X05.@X08
-
- 4@X05)@X08 Wrap the matches around the end of the fuse@X05,@X08 with the heads of the matches
- touching the very end of the fuse@X05.@X08 Tape them there securely@X05,@X08 making sure not
- to put tape over the match heads@X05.@X08 Make sure they are very secure by pulling
- on them at the base of the assembly@X05.@X08 They should not be able to move@X05.@X08
-
- 5@X05)@X08 Wrap the cover of the matches around the matches attached to the fuse@X05,@X08 making
- sure that the striker paper is below the match heads and the striker faces
- the match heads@X05.@X08 Tape the paper so that is fairly tight around the matches@X05.@X08
- Do not tape the cover of the striker to the fuse or to the matches@X05.@X08 Leave
- enough of the match book to pull on for ignition@X05.@X08
