In considering the various materials which are used we come first to wood for the framework. It is possible to make a kite from odd scraps of wood, or even hedgerow sticks, but in the long run it pays to use the best. The wood must meet with certain requirements, namely; it must be light in weight, smooth, strong, and flexible. Fortunately, this kind is readily obtained in the form of hardwood stripwood. It can be obtained at woodworkers' and model-makers' shops. It comes in lengths up to 8 ft. and is of different thicknesses. When you are buying wood it is a good thing to tell the shopkeeper what you want it for, and he will help you in the choice. This stripwood is most suitable for the purpose, because besides being light and strong it is also fairly flexible, though not to the same extent, of course, as cane.
Cane is often specified in kite making, generally for the crossbars when these have to be bowed. That which is generally referred to is known as gardener's or staking cane. The hard outer skin gives great strength and flexibility to small diameter lengths. It is supplied both in the form of whole cane and split cane. Of course, one may split the cane at home when necessary by using a sharp knife or fretsaw.
Other cane mentioned in this book is called centre cane. It is cut from rattan, a species of climbing palm belonging to the East Indies. The hard outer skin of the rattan is stripped off, leaving the centre cane. It provides lengths of uniform thickness, but, however, it does not possess the strength of whole cane, as it lacks the hard outer skin. It may be used in suitable diameters when difficult shaping is called for, as it may be easily worked. Handicraft stores usually stock centre cane.
Covers for kites can be made in several materials. The most common is tissue paper. It is chosen mainly because of its lightness, but it is flimsy stuff and must be handled with care. Sheets of the paper measure 20 in. x 30 in., and various colours may be obtained. Following correspondence with a well-known paper manufacturers, and after testing, the writer recommends the following as being superior to tissue paper: one, pure unbleached greaseproof (17/18 lb.); two, mg. pure ribbed kraft (16 lb.). Both are light in weight and very strong. A good quality adhesive should be used for gluing the greaseproof. Both papers are obtainable in sheets measuring 20 in. x 30 in.
