Aeroplane weather vanes made by the author
The construction of the aeroplane is quite simple and the principal dimensions are given in [Fig. 93]. The construction is very well shown in [Plate XVIII]. If the foregoing problems have been satisfactorily worked out there will be no difficulty in constructing the aeroplane from the dimensions given.
The two wings are made from two pieces of tin of the required size with the edges folded over.
The body of fuselage is made of a long triangular piece of tin folded up on each side so as to form a sort of long tapering box. A cover is made for this box and divided into two parts so as to leave a cockpit opening.
The struts or wing supports are made from narrow strips of tin that are folded almost together for strength. The small guy wires had best be made from copper wire of small diameter. If it is difficult to get small copper wire, it may be possible to get two or three feet of insulated copper wire used for electrical purposes. Such wire is employed to wind small magnets used on electric bells. The insulation easily burns off. Copper wire solders very easily.
