diameter bolt, nut, and lockwasher sets. The upper and lower
body are now joined to complete Questor’s framework.
MOUNTING FRAMEWORK ON THE
PLATFORM

The next step in completing Questor’s body is mounting the
framework on the mobile platform. If you have chosen to
include the vacuum cleaner option in your version of Questor,
now is the time when it is installed.
Begin by placing the mobile platform on the floor so that the
castor wheel faces you, this is the front of the platform. Next
assemble the vacuum cleaner according to the instructions
included in the kit. Place the vacuum lengthwise on the plat-
form so that the vacuum’s motor faces the rear of the platform
and the hose outlet faces front. Make sure that the vacuum’s
mounting bracket sits flush with the platform. Once you have
the vacuum cleaner positioned correctly on the platform, lower
the framework onto the platform so that the Fs on the frame-
work face the front of the platform. The vacuum cleaner should
fit into the lower section of the framework as it is lowered onto
the platform. You will have to move the vacuum about with the
lower framework to accomplish this. Figure 2-28 shows how to
position the vacuum inside the framework.
Now that you have the vacuum and framework positioned
correctly on the platform, the mounting holes for each must
be marked and drilled. Begin by carefully marking the two
1/4-inch-diameter holes needed to secure the vacuum cleaner
unit. The bolts for this should be included in the vacuum
cleaner kit. Next mark the eight 5/32-inch-diameter holes
along the lower edge of the framework used to secure the
framework to the platform. You will use eight 1-inch 5/32-
inch-diameter bolt, nut, and lockwasher sets to secure the
framework in place. Now remove the vacuum and framework
and drill the holes. Replace the framework with the vacuum
cleaner inside, and bolt both in place. Press the bolts with
washers in place through the bottom of the platform, then
