Fig. 222 shows the construction from cardboard of the part of the cab marked G in Fig. 218. Half cuts are made along the dotted lines; the axle of the side wheels passes through the openings X and Y.
Fig. 223 shows the part of the cab marked H in Fig. 218.
Next cut a strip of wood, 4¼" × ¼" × ¼", for an axle for the side wheels, and round the ends; the wheels are 3 inches in diameter. Fasten these to the axle. Now glue the ends of the axle for the front roller to A and C. While this is drying colour the cardboard parts of the engine dark green. Bend J (Fig. 221) and glue this part to the inner sides of A B and C D. Cover the part marked K (Fig. 218) with paper; the part underneath K may remain uncovered. Glue the axle of the side wheels in position behind J, with just sufficient space for G to slip in between the engine and the axle. When the axle is secure glue G and H in position; G is glued to the inner sides of D C and B A, H is glued to the inner sides of blocks E and F.
The supports, O and N (Fig. 218), are 4½" × ¼" × ¼".
