Agree, the center of the hinge point should be aligned with the center of the axis of pivot. Thats how I do all my hinges. If not, which you could do, your shrouds will rub on the control surface. But thats just my opinion, I could be wrong.
Since your rudder leading edge is curved (convex) I assume the fin where it attaches is curved in (concave). If so, both you and ianober are correct. If, on the other hand your fin trailing edge is flat, then you would not need to embed the hinge point.

That would not work for a flat trailing edge with gap shrouds though Craig. You still need the pivot point of the hinge pin to be embedded in the rudder to avoid contact with the gap shrouds.
If it had "gap shrouds" it would not be "flat". I was referring back to the days when we either sanded a horizontal "V" shape or rounded the leading edges of our control surfaces and hinged them to flat trailing edges (fin, wing, whatever). No shrouds, no cavities no embedding hinges.
In this case, I think we're saying the same thing though because in essence, gap shrouds would make it a concave cavity.
In any event, looking at the picture of his fin he will definately need to embed his hinges (as you said in the very first reply).
