Fig. 333
The cannon in Fig. 332 consists of two cardboard wheels on an axle of stripwood, ¼ inch by ¼ inch, and the cannon is glued to a groove in the axle. It may be made of wood with a lead rim, or of two rolls of brown paper as in Fig. 333, where the flanges of the smaller roll A are gummed to flanges of B.
Cannon of the Fifteenth Century. This may be made of a short mantle-box (with lids on), cardboard wheels and pieces of stripwood, ¼ inch by ¼ inch. Fig. 334 shows the finished cannon. The stripwood cart which the cannon rests on must be made to fit the mantle-box; the shafts a may be straight or curved. Round holes may be cut at b. This same cannon may be fitted with axles, and swing between two posts. The wheels should be painted black, and the mantle-box covered with black paper, with bands of yellow paper at 1, 2 and 3.
