12. Turn the box top over and mount the motor using two of the 1 1/4 in long #4
wood screws. You may want to drill 1/16 in pilot holes in the wood after
you’ve marked the locations to drill. Your motor should sit flat on the board,
as shown in Figure 10-6. In order to make that happen, we removed the strap
that held on the motor and used a diagonal cutter to remove the hook that
the strap attached to. Also notice how the wires are insulated with hot glue
and strain-relieved. This is important, especially for this project.

13. Check to make sure your motor, shaft adaptor, and wheel are still centered on
the bearing. Place the rotating tabletop down on your work surface. Rotate
the bearing and wheel on the box top so you can see the exposed holes in the
lazy Susan you’re about to use to mount the rotating tabletop through the 1/4
in access holes you drilled earlier.
