Procedure
1. Fill the 8 wine bottles with saturated salt water up to where the
bottles start to curve. Fill the rest of the bottles up with motor
oil. Drill a hole in the center of each pop cap and put a bolt through
the hole upside down. Place a wire connector on the top of the caps.
Seal the caps with RTV. Wrap the bottles in aluminum foil so that no
salt water can be seen. Wrap electrical taped around the sides of the
bottles. The bottoms should have foil, but no electrical tape. Build a
box to put the eight bottles in and spray paint it flat black. The
bottles should fit snugly. Place a piece of glass on the bottom of the
box and put aluminum foil over it, and then put the bottles in the
box.
2. Build 6 supports for the primary coil using particle board. There
should be a 30 degree angle of elevation, an effective height of 3.5",
and an effective width of 6" on each one. Cut 15 grooves on the tops
of them. Wrap the copper tubing in a spiral using the grooves.
3. Wrap the 22 gauge magnet wire around the PVC pipe and put
polyurethane over the coil.
4. Make the spark gap by using RTV to put the copper pipe on the
plastic. There should be a .03" gap between each one.
5. Use the ducting to construct a toroid with a 29.2" outside
diameter.
6. Secure the primary coil, secondary coil, spark gap, capacitor box,
and transformer to a piece of particle board. Hang the toroid from the
piece of PVC pipe with two perpendicular pieces of fishing line.
7. Wire the two circuits as shown below.
