See Chapter 4 for more information about choosing drill bit sizes for par-
ticular components. In that chapter, we also offer advice about how to
customize a box for your projects. Make sure you use safety glasses
when drilling, and clamp the box to your worktable!- Slip the shaft of the switches through the drilled holes and secure
with the nuts provided. - Solder the black wire from the battery pack to one lug of the on/off
switch and solder an 8" black wire to the remaining lug of the on/off
switch, as shown in Figure 13-15. - Solder an 8" wire to each of the two lugs on the pushbutton transmit
switch, as shown in Figure 13-15. - Solder 6" wires to each of the two lugs on each of the three switches
mounted on the cover, as shown in Figure 13-16.
If you have 22 gauge stranded wire, consider using it for connecting the
switches mounted on the cover. Stranded wire is more flexible, which
makes getting the cover on the box easier. As we discuss in Chapter 4,
solder the end of the stranded wire to gather all those loose strands.
