I'm starting to do some filling (so it won't be all left to the end
of the job) and am wondering how others dealt with the hinges already
riveted to some surfaces. It's the rudder I'm starting with - there
may be different questions with the other surfaces!
I have 2 inter-related questions.
If you don't fill thickly enough to raise the surface above the level
of the hinge knuckles, how do you prevent accidental abrasion of the
hinge knuckle while sanding? Obviously if your hinge flange + BID
reinforcements is a bit thick so that the knuckles don't protrude
anyway, this question won't arise - but the next one will apply by
default.
If you do fill thickly enough to raise the surface above the level of
the hinge knuckles, how do you get a neat line along the hinge
knuckle? Is there some clever way of masking it off while filling?
Removing excess filler in this area seems very difficult without
damaging the hinge (even a small scratch on it could be a dangerous
stress-riser).
All thoughts welcomed!
regards
Rowland
