What is the common practice regarding the above question - how to attach piano hinges to a wooden structure (elevator, rudder, aileron, etc).

The two most obvious alternatives in my mind (not necessarily applicable to aircraft) are 1) bolts and nuts, 2) wood screws. Rivets seem to be out of the question here.

Is #2 (wood screws) even possible/acceptable on aircraft at all? It would be the most convenient way, especially when access to the back side of the spar is not available or not easy to organize.

Thanks in advance for any expert advice...

My plans say nuts and bolts cut and shorten the hinge pin and crimp the ends so it never comes out. I wouldn't want to do piano hinges on wood any other way.
