undercarriage
This drive mechanism rotates the first wheel, which drives the wheel arm to turn the
other wheels on the engine. We'll look at how to set up this relationship in the animation
chapters later in the topic. For now, let's make the steam pumps using poly objects, as

Figure 4.93
The steam pump is made of two cylinders and an extruded cube.
Figure 4.94
The drive mechanism is made of a couple of extruded cubes
flanked by poly cylinder rods.
