The first two methods described result in wheels that look like the heavy truck wheels employed on actual trucks.
Another type of wheel may be built of the flanged pushed-in lids. In this type the lids are soldered together in just the opposite way as that described in the third method, so that the flanges are on the outside of the wheels. These wheels are generally used for belt wheels on the mechanical models, [Fig. 50], B.

Making a Toy Auto Truck (Continued)
FORMING THE CHASSIS—USING THE WOODEN ROOFING FOLDER—FOLDING—USING THE VISE FOR SHORT FOLDING—USING THE HATCHET STAKE FOR FOLDING
Forming the Chassis.—The chassis or frame of the truck may be made from a single piece of tin cut from a gallon fruit can. All four edges are turned down so as to form a shallow tray or box.
Cut a piece of tin 12¾ by 4¼ inches. Use the dividers to mark off a line ⅜ of an inch inside all four sides, but be sure that the tin is cut perfectly square before you do this inside marking. Cut in to the lines A A on all four of the darkened lines as shown in [Fig. 51], A.
Place the tin on a sharp-edged block and fold down the long sides 1 and 2 first. Remember not to try to fold these long sides or folds down all at once, but rather go over them two or three times lightly with the mallet as they are being turned down at a right angle. Take care that the tin folds over exactly at the line.
When the sides 1 and 2 are folded down at right angles, fold down the ends 3 and 4. This will leave four small ends of the two long sides projecting beyond the ends as shown in [Fig. 51], B. Fold these in over the ends of the chassis with a mallet. Hold them in place with a pair of flat-nosed pliers and solder them to the ends where they touch, so that the chassis appears as shown in [Fig. 51], C.
