Introduction: How to Make a Boomerang

About: I like to create things, handmade weapon, arduino projects, science and some crazy staff! Also I like to capturing videos about my projects and I have YouTube channel - MadGyver!

Hello friends, this instructables is about how to make a simplest boomerang. This type of boomerang is very simple to build and throw and catch. Yes, it returns right in hands!

You can watch all process of making this simpliest 4 blade X shape boomerang in my video[VIDEO LINK]

Step 1: Collect Some Wooden Boards

We need 2 piece of wooden board with width about 4 cm, 7mm thick and 30 cm length. You can use another sizes, so there is a space for experiments. Process your boards with sandpaper to make it clean if it's needed.

Step 2: Crosswising

Both blades will be fixed crosswise, one blade inside other blade, at half. So let’s make a groove.

Step 3: Cut Off the Square Piece

Use knife to cut off square middle part and rid of leftovers.

Step 4: Rough Aerodynamics

Now we need to process blades into airplane 's wing shape, it is about ascensional power. Use a knife to shape it.

Step 5: Improved Aerodynamics

Continue with file and sandpaper

Step 6: A Little Drop of Glue

And now it's time to fix blades with glue. Use any glue for wood, or epoxy. Then press blades for a while, and wait the glue to dry.

Step 7: Perfect Aerodynamics!

After this use sandpaper to create a perfect smooth aerodynamic surface. Boomerang is almost done!

Step 8: Heavy Ends

Usually this type of boomerang doesn’t need of tuning and setting, but if it is very light and stops spinning in the end of trajectory, just heavier the ends of blades. Make holes and put sinkers inside them. Fill roughness with glue to reduce air drag.

Step 9: Add Some Paint

Use acrylic paint to make your boomerang colorful and bright. BUT REMEMBER! Never paint boomerang with green color!

Step 10: Flight School

If there is a wind, you need to throw your rang at the angle about 90 degrees from wind. Hold it like this way, and throw in horizontal direction. It will make a loop and return to you along the wind. Catch it with top down "clap" moving of your hands. Just WATCH A VIDEO, I captured a process of throwing and catching with a camera on my head =).

Protect your fingers! Good luck.
