Building the containers/skeleton

Always acquire and modify the skeleton (containers) before you manufacture the explosives. You can f example use a large barrel or medium/mini barrel to place the main charge in. Confinement will ensure an optimal detonation and subsequent destruction power. Non-confined explosives will due considerably less impact unless you design the skeleton in a way that you can create a shaped charge (one directional charge against a specific target).

Blasting cap container

As for the blasting cap container; you can f example use a 0,62 cm x 6,25 cm long alu tube which can usually be bought at hobby stores/model building stores. There are items which is used as landing gear for planes that might prove useful. Buy a board plastic straw to prevent the priming mixture to reacting the with metallic body even when aluminium is used.

Booster container

Use a larger metal/alu pipe.

Detonator-trigger

There are four different types of detonators you can use in order to activate your primary explosive (blasting cap):

1. Mechanical detonator

2. Electrical detonator

3. Chemical detonator

4. Fuse detonator

I would suggest choosing one of the following detonation devices:

Fuse (EASY)

Buy visco fuse or similar high quality fuse. Choose the most reliable fuse type (6mm in diameter is usually more reliable than 2,5 mm fuses but is harder to come by). Cover the fuse in surgical tubing or the sparks from the fuse may cause early detonation (from either nitro/fuel /chem fumes, or sparks may come into contact with load). There are several different types of fuses. Burn rate is usually 1cm per second (this should be specified on the supplier site) so if you want 2 minutes for evacuation you will need 1,2 meter fuse etc. Web addresses to European suppliers are found at pyroforums. If you’re going to use a fuse, you must normally add a little (1g-3g black powder or similar in the receiving end of the primary charge in order to successfully initiate the rest. You should create a blasting cap and arrange a test prior to operation.

Wireless Radio Firing Systems (MODERATE)

Sold by companies specializing in fireworks detonation systems. Consists of two parts: 1 x Receiver with battery source and 1 x Remote control with battery.

Like the 1Q version from: http://www.e-madeinchn.com/FiringSystems.html

There are other European, US and Chinese companies selling similar items. The 1Q version sold on that site costs 16 USD + 5 USD shipping. This specific version is a 6V with relatively short range: 200 m. You basically just place the receiver close to the charge and plug wires into the chromatic wires, similar to the one you find in light bulbs.

Mobile phone (MODERATE TO HARD)

Same principle as above, just that you use the battery power from the receiver mobile. When you call the receiver mobile with your transmitter mobile (providing you have sorted the wiring from your receiver mobile into the detonation cap (chromatic wires)
