Joints
The simple butt joint is all that is generally needed in kite making. It may be formed in two ways: first, by laying one piece
of wood across another, and fastening together with glue and binding thread; second, by fastening two ends together with glue and a nail. When properly made, the butt joint combines simplicity with strength.
The halving joint is used to make a framework all on one level, that is, one part does not stick out above or below another. This makes for neatness, and enables the kite cover to lie flat upon all the framework. This joint, to be effective, must be made accurately. A good joint is one in which the parts need a gentle tapping home with a mallet. Both these joints are described and illustrated in the instructions for making kites in Chapters 1-6.
Gluing
When using glue, first read the directions on the container. It is surprising how many people don't do this, and then blame the glue because it won't stick. These directions usually state the approximate drying time, that is, the time to be allowed before the parts are brought together. Drying time is fundamental to successful gluing.
Don't use too much glue. Too much is nearly as useless as none at all, and far messier. After they have been set aside for a while to dry, the two parts are pressed firmly together. The ultimate strength of the joint depends upon the closeness of contact of the two pieces of wood. The aim is to expel all air bubbles, which are the enemy of good joints. The work is best done in a fairly warm room. It is an advantage to cramp the joints and to allow the glue to set hard overnight. Metal cramps can be bought quite cheaply.
Binding
In addition to the use of glue, most kite framework joints are bound round with thread or fine string. Use thread for small kites and fine string for the larger sizes. Smear the binding with glue to keep it in place. Illustrations in Chapters 1-6 will show how to achieve neat and effective binding of joints.
