Diamond Charge (fig 2)

Diamond Charge (fig 2)

General. The diamond charge is used for targets similar to those for which the saddle charge is used but requires access to the complete shaft. When detonated, the shock waves, meeting in the center of the charge, are deflected at right angles cutting down into the target.

Preparation. The long axis of the diamond-shaped charge must be equal to the circumference of the target. Use sufficient explosive to be sure that both ends of the long axis touch. The short axis of the diamond charge is equal to one-hair the long axis. The depth or thickness of the diamond is always one-third block of C4 or 1.67 centimeters to cut a target composed of 2 centimeters of high carbon steel. However, the explosive need only be one-half centimeter for targets of mild steel. Protection of charges is the same as that noted above for saddle charges. Simultaneous detonation is mandatory. Equal lengths of detonating cord may be used with non-electric blasting caps crimped to the ends or electric blasting caps fired simultaneously.
