I’ve found
that the best way is to pound a straight row of nails into the
wood. Use one nail
for each cue you wish to have, plus one extra nail to serve as
the common ground. Thus
a 5-cue nail board will have a total of 6 nails.
I recommend separating the common ground nail from the
others by a large gap to make it easier to recognize during the
set up and wiring of your show.
Number the nails by writing on the wood with a marker.
Cut as many
pieces of the 2-conductor as you need (they should be at least
50 feet in length), then separate the two wires from each other
by about 6 inches from either end.
Attach small alligator clips to each one.
On the “fireworks end” of the shooting wires, connect
the alligator clips to nichrome filaments or ematches (discussed
in depth elsewhere on this page).
On the nail board end, connect one alligator clip to the
appropriately numbed nail, and the other to the common ground
nail.
To use the
system, connect the clamp of one end of the negative power cable
to the battery and the other to the common ground nail.
Then connect the positive clamp to the positive post of
the battery. To fire
each cue, simply touch the clamp of the other end of the
positive cord to each numbered nail.
As shown in the diagram, touching each nail completes a
circuit to a given cue, igniting the igniter. |
