DRINK DISPENSER

Figure 5-10 shows the parts layout for Questor’s drink dis-
penser. The dispenser’s base, on which all of the components
are mounted, consists of a 9 1/2- 9 1/2-inch piece of 1/8-
inch plywood. The unit, when completed, is mounted in
Questor’s upper framework, hence the 9 1/2- 9 1/2-inch
base. As you can see by the previous figure, many parts for the
dispenser must be modified or fabricated before they are
mounted; the first of these is the 12-volt pump itself.
The pump (listed in parts list; your pump could be different)
has two large input/output spouts that have to be removed so
that the remaining parts of the spout can accept the narrower
tubing used to pass fluids through the system. Figure 5-11
shows what portion of the spout to remove. Next, two sheet
metal brackets need to be cut; these brackets hold the drink dis-
penser’s tank, a 1-gallon milk container, in place and prevent it
