In the same way the lantern is fastened to the upper platform and the latter to the upper column, after similar railings have been made round the upper platform. Lastly the pyramidal top is fixed on the lantern, by either paper hinges or flanges. Now cut a piece of stripwood, ¼ inch by ¼ inch, of the right length, so that it passes through the holes G and H in the lower column and projects about 1/8 inch over the doorway; into this projecting end screw a small screw-eye, pass a piece of string through it and bring the ends inside the door. This is the pulley by means of which goods are hauled up from the boat into the lighthouse. A ladder can be made of matches (as described in Chapter IX); two wire hooks are inserted at the ends, and it is hung to the doorway.
The lighthouse can be coloured grey and fastened to a piece of cardboard painted blue.
Plate XVI A LIGHTHOUSE
A Transporter Bridge. The supports for this bridge, A and B (Fig. 382), are two small wooden Bovril boxes (those containing one dozen one-ounce tins); their bottoms have been knocked out and they are mounted on wooden supports or on two smaller boxes of about the same width.
Fig. 382
Take two lengths of stripwood, C, D, 2' × ½" × ¼"; on to each of these glue and nail a similar length of stripwood, ¼ inch by ¼ inch (Fig. 383). Next the overhead trolley should be made (Fig. 384). The axles G and H are about 3½" × ¼" × ¼". The wheels are made of wood and can be cut from an old broom handle. Before these are put on, the two pieces E and F, which are 3½" × ¼" × ¼", are glued to G and H. C and D are placed so that the trolley runs easily along their ledges, the distance between them is measured and two pieces of stripwood (J in Fig. 383) are cut, by means of which C and D are fastened together. This frame can rest on A and B. There is no need to fasten it permanently.
To each end of H and G, very small screw-eyes are screwed, K in Fig. 383, to which the strings or chains which support the car are attached—also two screw-eyes are screwed in at H and G.
