Set the bomb head on the A38A support stand and attach a 10cm length of fuse wire as shown

below in Figure 1. A pair of forceps or tweezers will be helpful for binding the wire to the electrodes.

First, fasten one end of the wire to the loop electrode (steps a thru d); then attach the other end to the

straight electrode (steps e thru h). Pull the loop downward to tighten the connections; then bend the

wire upward as in detail I. Place the capsule in the loop holder and bend the wire down to touch the

surface of the charge as shown in detail J.

Do not submerge the wire in a powdered or liquid sample. Better combustions will usually be

obtained if the loop of the fuse is set slightly above the surface. When using pelleted samples, bend the

wire so that the loop bears against the top of the pellet firmly enough to keep it from sliding against the

side of the capsule. It is also good practice to tilt the capsule slightly to one side so that the flame

emerging from it will not impinge directly on the tip of the straight electrode.
