I’ve been working on a boomerang for a couple days now. I got the design online and printed it out. I traced it onto some birch plywood and carved it out. I sanded it out and it looks pretty cool. I’m working on the airfoil carving things now but I’m not sure if you’re supposed to do both sides of the boomerang or not and in what direction and stuff. I’ve looked at some videos online but they don’t tell you or show you very well. Anybody know?
The "V" shaped boomerang will have two airfoil surfaces on the same side, one on each arm, but on different edges of the arms. Holding the boomerang in your right hand with the curve being away from you, the flat side should be against your hand and the leading airfoil will be against your thumb with the trailing edge against your fingers. You throw with a snapping downward motion, NOT a side arm.

In the "V" view above , the boomerang is laying flat and both airfoirs are on top. One foil is on the outside edge of the left arm and tapers to the right. The other airfoil is on the inside edge of the right arm and tapers to the right. When it is thrown to spin CCW ( as above) both edges will be respective leading airfoil edges.

I’m looking at a Kippar Ring boomerang as I answer this. It is delta wing shaped and has curved edges {tapered} on both the front and back. I would think this allows air flow as it turns to lift no matter which way it is facing. It is flat on the bottom and slightly rounded on the top. Hope this helps and many happy returns

PS what do you call a boomerang that won"t come back?
a stick!
