How to make boomerang


  • Shape

    I was prompted by Assassins Creed game series on such boomerang shape

  • 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 4

    Try to assemble, it shoult be like that

    Next, begin to give blades aircraft wing profile with knife. Attention! Look at the photos, do not confuse the side of blade!!!

  • 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


  • Step 7

    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.

  • Step 11

    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)
