#8 blasting cap
Materials required are a 10 inch waterproof fuse, a spent 223 cartridge, smokeless gunpowder from a pistol cartridge, mercury fulminate powder, sulphur, Potassium Chlorate powder. The last two are optional.

Combine 1 part Pottassium Chlorate with 1/8 part sulphur. This is mix 1. Mix one part mercury fulminate with 1/2 part mix1. This is the final mix. Fill the 223 shell half full of smokeless gunpowder. Fill the rest of it with the final mix. Put the fuse in the shell and close it off with water resistant glue. This is a #8 detonator which can be ignited by flame.

J1 Detonator
Materials required are a 12 inch waterproof fuse, a spent 223 cartridge, smokeless gunpowder from a pistol cartridge, mercury fulminate powder, sulphur, Potassium Chlorate powder.

Combine 1 part Pottassium Chlorate with 1/8 part sulphur. This is mix 1. Mix 2 part mercury fulminate with 1/2 part mix1. This is the final mix. Fill the 223 shell to the rim with final mix and the rest of the shell should be filled with smokeless powder. Place the fuse in the 223 shell, pinch and glue.

Compound detonators
Compound detonars are very useful in a situation with negative enviromental factors such as dust, rain, heat and cold. These detonars are a sure way of being sure the charge goes off.

Materials required are 15 inch fuse, Mercury Fulminate, smokeless powder, Pottassium Chlorate and a spent 30 06 shell.

Mix 1 part mercury fulminate with 1/8 part Potassium chlorate, this is mix 1. Mix 1 part mix1 with 1/8 part smokeless powder. This is the final mix. Put the final mix in the shell. Insert the fuse, pinch and seal.

Electric detonator
To convert any of the above detonators into an electric detonator an electric ignitor as used for rocket engines is used. This can be found at hobby stores. The ignitor can be inserted instead of a fuse and sealed but not pinched in the shell.
