The Hexagonal Kite

This is a simple flat wing kite, which can be readily adapted to different sizes. It has a lively performance, and does well in a gentle breeze. It is one of the class which is not bow shaped. This bow shape forms what is called the dihedral angle, and as we have seen in the comments upon the Tonking kite, dihedral improves stability. On the face of it, therefore, it would seem that the Hexagonal kite will not be so steady in flight as those which are bow shaped. But the reader will observe the way in which the bridle is tied. The purpose of this is to provide some stability in flight. This stability is further improved by the use of a flexible tail.

The framework is formed by three pieces, A, B, and C. These are 2 ft. 6 in. in length, and are cut from 3/8 in. square stripwood. Slightly notch the ends of the pieces, at D (Fig. 6). These pro­vide a seating for the string bracing. Make halving joints at the positions indicated (E, Fig. 6). These joints will have to be made with care, so that the saw cuts do not go too deep, and the pieces fit snugly. Use a fretsaw with a fine blade for this. Join the pieces with glue, after smoothing them thoroughly with fine sandpaper. It is recommended that cross-shaped strengthened, cut from 1/8 in. plywood, be fixed over these joints with glue and thread, as shown at F (Fig. 6). The completed framework should be smooth, firm and straight.

Next, add the bracing. Use thin strong string, which must be quite taut. To achieve this, make a temporary support as shown at G (Fig. 6), and lash it to the framework. Now tie the string to the top left-hand strut. Take it to the top right-hand strut, bind round and tie. From there, in the same manner, take the string to the other ends of the framework, and complete the bracing by tying at the point where you started. Remove the support. The bracing needs to be carefully and neatly done, to maintain the framework in the right shape, and to provide a firm support for the covering material.

The cover is made of unbleached greaseproof paper. It is chosen for its strength and lightness - very important factors. The paper is generally obtained in sheets measuring 20 in. x 30 in. so two of them will have to be joined together to give the required width. Lay the framework on the paper and mark the shape of the kite with a pencil. Add a margin of 11/2 in. all round for over­lapping, and cut out.
