Boomerang

Materials:

ü  A. 1/4" birch plywood, 20" x 16"

ü  B. Pattern Download.pdf

ü  C. Spray paint or clear lacquer

ü  D. Coping saw or scroll saw

ü  E. Sanding block or orbital sander

 

how-to:

 ü  Trace your pattern onto the plywood and use a saw to cut out the shape.

ü  Use a sanding block (and a lot of elbow grease) or an orbital sander to give each side of the boomerang an airfoil shape. The direction the airfoil faces depends on the hand with which you throw.

ü  In the middle of the boomerang blend the two airfoils together. You want the whole surface to be smooth.

ü  Give it a final sanding with fine grit paper then apply a thin coat of spray paint or clear lacquer to help protect the boomerang and make it look nice.

ü  Now you are ready to throw it. Find a very large, open space (at least a full baseball field). Hold nly the very tip of the boomerang in your throwing hand. You should throw the boomerang nearly vertical but angled outward sligtly. Aim just above the horizon. Throw it hard and overhand like a baseball and flick your wrist as you let go.

ü  Go fetch the boomerang. It will take some practice and experimentation before you can get it to come right back to you.
