- Traditional Method
- Baltic or Finnish birch plywood is recommended for boomerangs
- Boomerangs should have 107-degree angle for optimal spin
- Airfoil shape is created using sanding block or orbital sander
- Boomerang wings have leading and trailing edges for different throwing hands
- Surface should be smooth and protected with paint or lacquer
- Paper Boomerang
- 8.5" x 11" paper is used for the paper boomerang
- Paper is folded and cut into a screwdriver-like shape
- Final "L" shape is created by folding and inverting layers
- Every crease should be streamlined for proper flight
- Cardboard Boomerang
- Two 5" x 2.5" cardboard strips are used
- Blades are cut and glued together at intersection
- Folds should be 1" from end of each blade
- Alternative method uses popsicle sticks instead of cardboard
- Tips
- Practice makes perfect, don't give up if first attempt fails
- Wear gloves and safety glasses when using power tools
- Adjust flaps and make more precise as you make more boomerangs
- Try throwing with more spin instead of power
