The inside of the panel mounted socket is important. Notice on the outside view I used one metal machine screw and nut to attach socket to case. On the inside photograph, see fig 27, you can see I connected a ground wire from the circuit ground to the socket. This grounds the shield wire and improves performance.
A few more holes are drilled into the case. One for an LED, another for the neon bulb and the last one for a speaker. Space is tight in this case so these holes were drilled. One more hole is drilled into the side for the on-off switch.
Placing the tube into the assembly completes the wand, see figure 25. The copper pieces can be secured with a little glue or epoxy. I used a small amount of silicon to hold the components. The silicon holds everything together just enough. If needed I can disassemble the wand for upgrades or repair.
