Wheel Tire
The tire shown in Figure 4 is made from 1/4” craft
foam. Originally, I was going to provide a set of laser-cut
tires. Unfortunately, my laser is out of commission for the
time being, so I used my new KRmc01 CNC mini mill to
make them. For now, you will have to make your tires
manually by cutting a 1.85” circle out of 1/4” craft foam.
Use the wheel gear hub centered on the tire and either
mark or drill the four holes. Enlarge the holes to roughly
3/16”. The center cutout is . 8” in diameter, but its size is
not critical.
