FIGURE 6.13
Cutting, drilling, and
bending diagram for
head cover piece.

Cut another piece of the 1/6-inch thick aluminum to a size of 5-
1/2 inches by 6 inches. Cut, drill, and bend the piece, as shown in
Figure 6.14. This piece will make up the body cover, and is
attached to the head cover piece. This piece is identified as J.

Locate mounting bracket (F) and use it to join the head cover piece
(I) to the body cover piece (J) using two 6/32-inch 1/2-inch
machine screws and locking nuts, as shown in Figure 6.15. When
the two pieces are joined, wire three single AA battery holders in
series, as shown in Figure 6.16, so that a total of 4.5 volts are pro-
duced. Solder the negative and positive outputs to a 2-connector
male header. Use a glue gun to glue the battery holders to the top
body cover in the position, as shown in Figure 6.15. Figure 6.17
shows the completed top body cover from the top view.
