What is called
The Flange
of the wheel is practically another wheel, made of thinner material (Fig. 124), which is securely nailed to the first wheel (Figs. 125 and 126), with the grain of the wood of the flange crossing the grain of the wood of the wheel proper at right angles. The flange is made of one-inch board, and to prevent its splitting is reënforced by a strip of wood fastened on across the grain, with screws, as shown in Fig. 124.
When the four wheels are finished, and a hole large enough for a good strong axle is bored in the exact centre of each, you will be ready to begin work upon the car.
Set the Car-Bed Low.
The smallest boy will understand that the lower the bed of the car is put the less the danger of an upset, so instead of putting the axle, under the car, run them through the bed, as shown by Fig. 128.

Build the Axles
of four-by-four timber, and by the aid of a drawing-knife or a good, strong, sharp jack-knife, trim off the ends of the timber to the form shown in the diagram.
