HOW TO BUILD A CAR

A mouse, a bird, and a junkyard frog assemble a car from the ground up—cluing in readers who may be a bit vague on what’s beneath all those hoods…or at least what used to be.

Enlisting his green buddy Hank to supply the parts and feathered Phoebe to draw up the plans, Eli, “king of crazy ideas,” sees his latest project grow from a frame and some miscellaneous loose parts to a nifty blue convertible with a classic 1950s look. At each stage, Sodomka supplies clearly drawn angled or cutaway views with dozens of major components labeled, from “steering knuckle bracket” to “tie rod” and “ball joint.” The gas tank is labeled but seems to be missing, though, and readers who want to know what a “differential” actually does or the purpose of the “indicator switch” are out of luck. Lacey’s claim that an engine “is like the brain of the car” doesn’t bear close examination, either. Moreover, the finished auto isn’t much like most modern cars, as it has no electronic elements, for instance, and is powered by a three-cylinder engine (misleadingly billed as “regular”) quaintly fed by a long-obsolescent carburetor. With an auto under their belts (and with similar oversimplification), Eli’s “Scrap Pack” goes on to an even more ambitious enterprise in How to Build a Plane. In both volumes, closer looks at selected systems or related topics follow the storyline’s happy conclusion, and each broad trial-and-error step in the construction is recapped at the end.

Young makers will find the Scrap Pack’s enthusiasm infectious, but even as broad overviews, these offer at best incomplete pictures.
