Once the dowels have been grooved, drill six evenly spaced, 1/4"-deep, 5/8" holes in the face of the "gutted" 7-1/4" disk . . . placing them about 3/4" on center from its outer edge. Repeat this procedure on the like-sized uncut blank . . . boring from the side opposite the kerfed surface, if you've included one. Drill a 1 "opening through the center of the latter circular plate, and fasten your bell transformer and light socket to it as shown in the illustration, using the mounting holes provided in these pieces of hardware as drilling guides.

You're now ready to assemble the cage and wire it. Glue the slotted dowels into their respective receptacles in the upper and lower large disks, and—after allowing ample time for the adhesive to dry—coat the framework and the other two wooden components with shellac or polyurethane. Now mount the two transformer leads to ,two double-nutted machine-screw termi nal posts (which you should place at points 180° apart, on either side of the light fixture), and snug down the primary nuts to hold the "poles" in place. You can also, at this time, solder the rectifying diode in line . . . as shown in our wiring diagram.
Next, fasten a ring tongue terminal securely to the end of your stainless steel wire, and begin to loop the strand by first fastening it to one of the terminal posts with a secondary nut, then winding it counterclockwise. Once you've gone past the contact post opposite the one where you started, drop the wire down to the second tier of slots, then skip alternate levels of notches as you go. When you reach the lower end of the cage, cut the wire and fasten it between a pair of washers held tight by a wood-screw anchor placed near the edge of the base and on the same side as your starting point. Finish the job by winding a second wire—again, counterclockwise—between the remaining terminal at the top and a second screw mount in the base, using the "unstrung" slots in the dowels. (Of course, since these two sets of wire will be oppositely charged, they shouldn't touch each other at any point in their circuit.)
