10. Mount the motor. First, slide the shaft adaptor on your motor and stick it
through the centered hole you drilled earlier. It should look like Figure 10-4.

11. Place the plastic wheel on the shaft adaptor. The wheel should be centered on
the bearing and will be resting on top of it (and the shaft adaptor) at this
point (see Figure 10-5). Adjust the position until the wheel is centered and the
shaft adaptor is not rubbing against the inside of the 1/2 in hole you drilled
earlier.
