It's the best there is for boomerangs, but don't worry if you can't find it. A good quality plywood from lumber stores should do nicely too. I recommend searching for a 6 mm (1/4 inch) plywood, with 3 to 5 layers. A or B are good, but BB and C are not because they can contain large knots and filled up voids.
Introduction: How to Build and Throw Your Own Boomerang
Long-distance boomerangs are most frequently made of composite material, mainly fibre glass epoxy composites. Long-distance boomerang throwers aim to have the boomerang go the furthest possible distance while returning close to the throwing point. In competition the boomerang must intersect an imaginary surface defined as an infinite vertical projection of a 40 m (130 ft) line centred on the thrower.

Watch closely as your boomerang goes out and starts to return to you.6. As the boomerang approaches you it will begin to level out and fly like a frisbee and descend to the ground.7. If you threw it with the correct amount of force it should descend and come right back to where you are standing. Having finished cutting out the rough shape, it is time to start sanding it into its final form.1. Next, sand all around the edges of the boomerang so they are rounded.3. Take off all the rough points on the boomerang so you can run your hand over the edges with no catches.
The Components for Aboriginal Boomerang Design 2
For older types of long-distance boomerangs (all types of so-called big hooks), the first and last third of the flight path are very low, while the middle third is a fast climb followed by a fast descent. Nowadays, boomerangs are made in a way that their whole flight path is almost planar with a constant climb during the first half of the trajectory and then a rather constant descent during the second half. Boomerangs return to the thrower, distinguishing them from throwing sticks. As one of the earliest man-made flying objects, there's something almost magical about the boomerang.
Boomerang Team in Greenfield, Mass., one figure stands out among the hacky sack players and pizza delivery guys gathering in the soccer fields, limbering up their throwing arms. The design here flies like crazy, so be sure to use them in a big space. And yes, they really do curve back towards you if you throw them right. Boomerangs work especially well when you throw them into a light breeze. They're going to have an airfoil which allows it to return. I’m a woodworker and blogger, and this is my woodworking blog.

Step 6: Step 6. Sand the Foils
The individual World Champion title was won in 2000, 2002, 2004, 2012, and 2016 by Swiss thrower Manuel Schütz. In 1992, 1998, 2006, and 2008 Fridolin Frost from Germany won the title. Sand with the coarse, medium, and fine grits in that order before using linseed oil. Rub a generous coating of the oil into the whole boomerang and let dry.
How Do I Throw One?
Once you have the desired shape, go over the airfoil in progressively finer grits of sandpaper to give it a nice smooth finish. After you have properly gripped the boomerang and are aligned 45 degrees from the wind you are ready to throw.1. Hold the boomerang at approximately a 45 degree angle from vertical on release.2. The throwing motion will be similar to an overhand baseball throw.3. Make sure to throw hard so that the boomerang will return to you.4.
Make notes on any deviations or issues in its flight pattern. In addition to adding a beautiful finish, this step is essential in bringing out the natural beauty of the wood used for your boomerang. The proper sanding techniques and application of finish will not only provide an aesthetically pleasing appearance but also contribute to its longevity and durability.

However I have had students that create great looking boomerangs for display. Do not paint, stain, or seal your boomerang until you have thrown/tested it. Also paint and stain may decrease your boomerangs performance. The boomerang is an aerodynamic stick that was designed by Aboriginal people to be used as a weapon for hunting. It is shaped like two connected wings whose aerofoil design forces it to travel in a curve and return to the thrower.
I have NO legal responsibility for your actions while using this. Once you're satisfied with the flight of your boomerang, you can go ahead and paint it in whatever colors you like. Before you do that, give it a quick sanding with the fine grit sandpaper to get it extra smooth. But be careful not to sand too much, because you don't want to change the flight characteristics anymore. I use acrylic paint, because once it's dry, it doesn't wash away with water (like water color paint for example).
Ultimately, mastering the art of cutting and shaping wood for a boomerang requires patience, practice, and attention to detail. By following these step-by-step instructions and taking into consideration different wood characteristics, enthusiasts can create beautifully crafted boomerangs with excellent flight performance. Are you interested in learning how to make a boomerang woodworking? Boomerangs are not only fascinating objects with an interesting history, but they also hold significance in various cultures.
"This boomerang inspired me to put a shallow hollow, or undercamber, on the bottom of my boomerangs," Darnell says. And, yes, there is such a thing as a world boomerang championship. (Next year it will be held in Seattle.) National clubs thrive in the United States, Germany, France, Japan and England. There are rules, regulation fields, exhibition games and individual and team events.
More than one layer should be used for added protection. If you want, paint or add designs with sharpie before finishing. 2.) Files - In this project I will be using three different files to create the curves and airfoils of the boomerang, but it can easily be done with just one, or even entirely with sandpaper. This means that while the wing at the top is spinning at the same speed as the wing at the bottom, it is actually moving through the air at a higher rate of speed. Made for the Maximum Time Aloft event at competitions, the MTA has asymmetrical wings that present more surface area to the wind, maximizing lift. And at a mere half-ounce, the 13-in.-wide MTA floats on the slightest updraft.
If your plywood is chipping too much, use a blade with smaller teeth. Once you're done, take your coarse sandpaper and sand the edges to get rid of any imperfections. The experts aren't really sure when and where people first developed returning boomerangs, but the Aborigines of Australia are generally credited with the invention. This might have been pure accident or it might have been the result of design experimentation. One theory is that an Aboriginal hunter fashioned a smaller kylie with a more angled curve because he or she noticed how a bird held its wings in a pronounced V shape while soaring through the air.

Though Darnell's degree is in regional planning, he is a self-taught engineer and avid consumer of trade magazines on materials science. He is also a tool-and-die designer, and his list of inventions includes chest protectors for sports, helmets for lacrosse and ice hockey, and a wood-burning stove that is sold all over the world. Some boomerangs have turbulators — bumps or pits on the top surface that act to increase the lift as boundary layer transition activators (to keep attached turbulent flow instead of laminar separation). If you find your boomerang consistently sinks soon after throwing, flex the boomerang upward to give you more dihedral (upward warp).
