Cliff, Roger - sorry for delay in responding. Both your suggestions
rely upon the hinge not being assembled. I have been following the
instructions in the manual, and thus my rudder hinges are assembled
with the hinge wire safetied. (Incidentally, once the hinges are
rivetted on, I can't see how the hinge wires can be removed or
inserted without cutting away quite a bit of the edge of the adjacent
hinge flange layup.) I have not had a problem with the filler getting
into the hinge-wire hole - when properly made up, it's much too dry
to get anywhere by capillary action like plain epoxy does. The
presence of the other hinge leaf prevents Roger's idea being used,
but it's something like that I feel is needed.
I have put masking tape over the hinge knuckle, with parcel tape on
top for better epoxy resistance. That stops filler adhering to the
hinge, but doesn't help with achieving a nice-looking edge to the
filler. I suppose I could tape on a tiny triangular-section fillet -
well, the hypotenuse would have to be a quadrant of a circle, not a
straight line - but that seems a bit fiddly and I'm not sure it would
stay on during all the work.
Still looking for better ideas!
regards
Rowland
