Recently, we had champion boomerang thrower Logan Broadbent from the US Boomerang team show Jeremy how to make a DIY boomerang . This article will not only show you how to make your own DIY boomerang out of common materials but also how to throw a boomerang. 6.) Wood - Used to actually create the body of the boomerang, I used 1/4 inch project board left over from another design, but this can be bought in a 2x2 foot size at home depot for cheap. No boomerang without wood, so find a sheet of plywood first. I'm using a 5 mm (13/64 inch) special plywood called aircraft birch plywood. It has 2 layers per mm (10 in total), which makes it super strong but super expensive.

Multiple coats can be used so do as many as you want, but one should be sufficient. Use a sharpie/pencil to trace around the cutout onto the project panel. Bring your friends and show them how magical it can be to throw something that returns to you.
Step 5: Sanding the Edges and Contours
When we talk about boomerangs, we usually mean the curved devices that return to you when you throw them, but there are actually two different kinds of boomerangs. The kind we're all familiar with, returning boomerangs, are specially crafted, lightweight pieces of wood, plastic or other material. Traditionally, these are basically two wings connected together in one banana-shaped unit, but you can find a number of different boomerang designs available these days, some with three or more wings. Most returning boomerangs measure 1 to 2 feet (30 to 60 cm) across, but there are larger and smaller varieties.

When holding the boomerang you want to hold the end so that the open V faces away from you, as in the picture.2. Place your other 4 fingers on the bottom side much like holding a Frisbee. After sanding, it’s time to apply a finish to enhance the appearance of the boomerang woodworking. Varnish or lacquer can be used to not only add a glossy sheen but also protect the wood from moisture and wear over time. Apply thin coats of finish, allowing each layer to dry completely before applying the next. Once all coats have been applied, allow the finish to cure according to the manufacturer’s instructions for a professional-looking result.
If you are right handed, mark the right edge of every wing/blade of the boomerang, and vice versa if you are left handed. This is the edge that you will be tapering to create the wing shape. First let's consider how a primitive hunter might have come up with a non-returning boomerang. We know that at some point people started using the rocks and sticks they found around them as crude tools. One very early invention was the club, which is just a stick that you hit something or somebody with.
These are also curved pieces of wood, but they are usually heavier and longer, typically 3 feet (1 meter) or more across. Non-returning boomerangs are effective hunting weapons because they are easy to aim and they travel a good distance at a high rate of speed. There is also such a thing as a battle boomerang, which is basically a non-returning boomerang used in hand-to-hand combat. Once the boomerang woodworking has been cut and shaped to the desired design, the next crucial step is sanding and finishing.

By following these steps for testing and tweaking, you can ensure that your boomerang woodworking not only looks great but also performs admirably when thrown. After making adjustments, repeat the testing process to see if the changes have improved the boomerangs’ flight pattern and return accuracy. It may take several attempts and adjustments to achieve the desired results. Take your boomerang to an open outdoor area, free from any obstacles or people. Hold the boomerang correctly and throw it with a smooth, level arm action.
Removing more wood from the trailing edge will also increase lift. A third option is to remove some wood from the underside of each leading edge, as shown in the picture. As you can see in the diagram, the two wings are arranged so that the leading edges are facing in the same direction, like the blades of a propeller. At its heart, a boomerang is just a propeller that isn't attached to anything. Propellers, like the ones on the front of an airplane or the top of a helicopter, create a forward force by spinning the blades, which are just little wings, through the air. This force acts on the axis, the central point, of the propeller.

Do a sandwich catch if the boomerang has slowed enough. Also, throw the boomerang so that you are aiming to keep it about eye level. It will climb on its own because of the airfoil and dihedral. It is, therefore, quite an important step to add the airfoils. Check the shape of the wing by viewing it from the wingtip. Continue filing until it resembles the above images, and then repeat on each of the other wings.

Carefully make relief cuts around your pattern and cut it out. I used a jig saw for this but a scroll saw and band saw work well also. If you are skill with any of these tools you can cut some of the bevels for the edges. I recommend a jigsaw and anything that can be used for sanding. Hand sander, palm sander, orbital sander, disk and belt sander, drum or pad sander mounted on a drill, etc.
For example, you could alter the angle to the wind, the height and power of your throw, the angle at which you hold the boomerang or a combination of these. If that doesn't help, there are a few things you can do. The wings are set at a slight tilt and they have an airfoil design -- they are rounded on one side and flat on the other, just like an airplane wing. If you've read How Airplanes Work, then you know that this design gives a wing lift.
Round the front edge just slightly, it will make it easier to throw. Here I sanded the back of the boomerangs tips with a fade (deepest sanding at the bottom). You only need to sand until the wood sheds to a different color... A good way to test that you have sanded enough is to put the boomerang on a flat surface with the back side down and press on the edge, the rest of the boomerang should lift up very slightly. The drilling is not necessary because the boomerang at this point will come back to you without the holes. It only requires a small hole near each wing tip and a larger hole in the center.
