Mounting the wheel
hub.

Secure the L-brackets and mount the wheels using wheel hub #1 and
a 1" 4-40 bolt with a washer so that there is not too much wobble.
Figure 6.28 shows the side profile. Note: You may want to substitute
the L-brackets for casters that will allow the front and back wheels to
swivel freely. I found that the L-brackets work well on smooth surfaces
