PreamblePreamble

Once boomerang was the most powerful and deadly weapon. Now mainly used in sports and decorative purposes. By the way, aborigines made their boomerangs without using any tools (as there were no instruments). We are living in the 21st century and have a bunch of tools for woodworking, so make boomerang will have no troubles.
As you learn later, make boomerang of wood is not too difficult, especially after a few attempts. Also you can read all "how to make boomerang" topics on this website and you will be a master. Follow to boomerang tag.

  • Step 1

    All sizes are taken at random, the width of the blade is width of a slat, the rest - pure improvisation and experiments
    Here are the sizes that I've got.

    Material is a pinewood, you can use a birch to make boomerang heavier and more wind-resistant

  • Step 2

    Cut the lines with hacksaw at half thickness of the plank (not more !!! without distortions !!!) on both sides, according to the design

  • Step 6

    At this stage, each blade of boomerang should be given a slight bend at the convex side of the wing. Put all three blades on the tank of boiling water (a short distance from the water, vapor should envelop blades), and wait a few minutes. Wood will turn wet and become soft, gently give them a little bend.
    Bend blade around cylindric thing, like bucket

  • Assembling

    Treat surfaces with rasp before gluing. Then use any adhesive glue for wood. At the photo you can see traces of the clamps, which I was clutching a boomerang during glueing.

  • Step 8

    Also, you can see the seams. They can be repaired, I use a mixture of PVA and fine sawdust and wood flour.
    Epoxy glue is better, but it's harder to treat

  • Step 9

    Let's process boomerang with a file and sandpaper. We seek to maximize the perfection of form and smoothness of curves (this is about boomerang, not about girls).
    The hole in the center I increased and made round.

  • Painting


  • Step 10

    The main part is coming to an end, the homemade boomerang is ready to flight. But let's paint it.
    Usually I cover my boomerangs with a transparent varnish or colorless protective impregnation for wood. This boomerang I decided to paint with color. Cover surface with tape for accurate paint.
    Boomerang is placed on support from a sheet of plywood, which hammered three nails spikes upward, to not disturb the wet paint.

    After removing tape

    You can make holes at the end of blades to make boomerang less agressive and decrease its spin speed at the end of flight trajectory (just before you catch it)

So let's watch a video! It's very hard to catch fast spinning boomerang with one hand...


Here it is a next video with "Abstergo" boomerang, also featuring my "Hieroglyph" rang.

P.S. You can see a horrible crash of boomerang nearly the end of video =(

ResultsResults and tips

  • This is perhaps the most complex and tricky design for a homemade boomerang, but i haв no problems with it
  • Boomerang is very quick and has short-range flight.
  • Due to the extra weight of paint and a high speed it was not afraid of a gentle breeze
  • A great gift. Just do not forget to teach the happy owner how to throw the boomerang
  • If the theme of boomerangs will be popular, I will record a step by step video about how to make boomerang of wood
