The boomerang is a throwing weapon which the Australian
aborigines and other primitive peoples even today continue to
use in war and for hunting birds. Boomerang-throwing is a very
interesting sport, and you can make your own boomerang very
easily, but of course you won't use it to kill birds. Even though it
isn't difficult, you must work with care and exactness, for a bungled
boomerang will not fly any better than a piece of firewood. Make
your boomerang of oak or birch according to the dimensions given in the
following illustrations.

Top view and cross section of a homemade boomerang. The short end of the boomerang stands up about 1 inch when the long end is lying flat on the table. The length of the arms is in a ratio of 4:5. However, the long arm has to be exactly as heavy as the short one, so it must be somewhat thinner. The bend near the middle forms an angle of about 140 degrees. It is especially important that the fibers of the wood have the same angle as the bend. If you saw or carve the boomerang out of a piece of wood in which the grain is perfectly straight, it will break when it hits.
