The boomerang is thought to be the first heavier-than-air flying object invented and used by humans. Australian Aborigines used the first boomerangs for hunting ten thousand years ago. People of all ages and walks of life have discovered boomerangs, and throw boomerangs for sport and recreation. Boomerang aficionados hold workshops and competitions throughout the world, and have also invented multiple-player boomerang games. You can construct your own wooden boomerang using simple woodworking tools.
Obtain a suitable boomerang pattern. Select from many free patterns available online. Patterns range from the traditional "V"-shaped boomerang to exotic three-blade designs. Some boomerang designs resemble animals such as a kangaroo or wolf. Use the pattern provided, or create your own design using the pattern for inspiration.
Trace the boomerang pattern's outline onto a piece of 5mm, 10-ply Finnish birch plywood. Use a pencil to trace the design.
Cut the plywood to shape using a scroll saw or band saw. Use a fine-tooth saw blade. Follow the pencil lines you drew from the pattern.
Smooth the boomerang's edges with 120-grit sandpaper. Sand until the outline is smooth.
Shape each boomerang wing's airfoil using a rasp and sandpaper. Use the airfoil shown on the boomerang pattern. The airfoil is very similar in shape and function to an aeroplane wing. The leading or front edge of the wing forms a quarter-round shape. The trailing or back edge of the wing forms a long taper. Begin shaping the airfoil with a rasp. Switch to 120-grit sandpaper to finish making the airfoil.
Finish your boomerang with sanding sealer. Use a brush to apply the sealer. Decorate the boomerang with paints, or use pyrography if desired. Select from modern or traditional Aborigine designs.
