6. Drill a^3 ⁄ 8 " hole about eight inches from the end in the side of the
   PVC pipe that will be to your left when you’re holding the parabolic
   microphone.
   You use this hole to feed the wires from the microphone cartridge to the
   box containing your circuit.


7. Slip one of the gaskets over the threads on the 1" x^3 ⁄ 4 " fitting. Then slip
   the threads from the inside through the hole in the dish.


8. Slip the other gasket over the threads and then screw the 1" x 1" fit-
   ting onto the threads.


9. Tighten the fitting by hand so that the gaskets are compressed a little
   and the dish is held securely between the gaskets.
   Figure 6-11 shows the handle assembled on the dish.
