                              FIGURE 1-3. Location of mounting holes.


                              unclamp the leg, flip the frame over, clamp the other leg,
                              and drill the hole on that side. Figure 1-4 shows how to
                              clamp and drill the holes in this way. You could have clamped
                              the frame posts in the vise, but round objects tend to slip
                              when you drill them.
                                 Now reassemble the first motorized wheel and disassemble
                              and drill the second. Figure 1-5 shows the top view of one
                              completed wheel. With both wheels drilled and assembled, it
                              is time to cut and drill the platform.



                              THE PLATFORM


                              The platform itself is simply a 20-   20-   1/4-inch piece of
                              plywood, cut from a larger 24-   24-   1/4-inch piece. While
                              simple in design and construction, it is the key element on
                              which all of Questor is mounted. Great care should be taken
                              to try to keep all of the various holes and cuts as precise and
                              as straight as possible. The easiest way to assure straight cuts
                              is to measure 4 inches in from the bottom edge of one side of
                              the board and 4 inches in from the top edge of the same side,
                              then connect the two points with a line. Figure 1-6 shows how
