The Wheels
What's a locomotive without wheels? You'll have two types of wheels: large ones that
are driven by the steam pumps and a pair of small wheels in front of the boiler (see
Figure 4.82).
To make the large wheels, follow these steps.
1. To create the outer rim of the wheels, cre-
ate a poly cylinder with Cap Divisions set
to 5 in the option box and Axis Divisions
set to 20. Scale the cylinder to
X
= 1.87, and
squash it down to
Y
= 0.145. Turn it up on
its side by rotating it 90 degrees in Z.
2. To hollow it out, select the inner faces on
the caps, as shown in Figure 4.83, and
delete them.

3. You should see a wheel rim similar to that in Figure 4.84. It's hollow on the inside,
so you need to close the inside rim. Select the front edges of the inside rim, as shown
in Figure 4.84, and choose Edit Mesh
➔
Extrude. Extrude the edges toward the back
side of the rim to close the inside rim.
