You can use a small wooden dowel rod or even a round toothpick. Simply drill a hole through the wood and hinge, push the dowel or toothpick through, apply glue, and trim flush with the outer wood.

I can understand that using a metal pin, cut flush with the airfoil, would provide a great improvement in retention and strength, as many people do.
However I wonder about a mere toothpick?
I can't imaging that a toothpick would add that much more strength over a properly soaked CA bond.
It would be interesting to test this.
