I thought about is a lot and I have decided to do it like I think it Caffenman...which is sinking the hinge in the elevator leading edge and sanding the vert. stab trailing edge with some 60 grit wrapped around a 5/16 dowell rod. This is a more time cosuming task but the way the elevator works with the fulcrum recessed and a radius sanded on the elev. leading edge is like killing 2 birds with one stone. Doing it this way seals the gap because the leading edge of the elev. never comes out of the concave sanded in the horz. trailing edge.
