Ok, someone correct me if I have it wrong..

I see "pinned hinges" being used where people mean "pin hinges" or "hinge pins".

"Pinned hinges" can include CA hinges, where someone has elected to insert a metal or wooden "pin" through the wood to hold the material in place.
Often toothpics are used.

"Pin hinges" or "hinge points", are dowl like ( usually plasitic ) hinges that are inserted into holes drilled into the control surface and wing.

The two are NOT the same thing.

I prefer PIN hinges, over PINNED hinges.
