Start by nailing the wood support to the base. That’s that for the stand. Next, wrap the aluminum foil around the card board tube about an inch from the end of the tube. Tape the foil in place.

     Remove 6 inches of insulation from a 3-foot piece of wire. Wrap the bared portion around the foil halfway up its length, and twist is tightly. Now you can mount the tube on the stand, using tape, rubber bands, or string. Leave about 3 inches of clearance between the bottom of the tube and the base.

     Take the other end of the wire from the foil and connect it (with the tip bared, of course) to the “COM” terminal of the coil, as shown in the drawing. If you’re using a Ford coil, try to solder the wire on. Otherwise, you’ll have to rely on tape to hold thire down.

From a second 3-foot piece of wire, remove 7 inches of insulation. This bared portion will have to be supported in the center of the tube. Use toothpicks as support bars. Push one toothpick through the tube just above the foil and the other just below it.

    To install the wire, form a hook on the end so that you can fish  it  onto  the  lower  toothpick.  After  hooking  the  toothpick, pull the wire snugly, and loop it around the upper toothpick. Keep the wire centered within the tube as best you can. Then connect the free end to the “PLUG” terminal on the coil.

    With the remaining wire, complete the connections as shown.
