Nicholas,
I centered the curve of the inspection plates around the elevator
torque tubes and made the tops level. Marking, drilling, de-coring,
layups, nutplates. I remember having pretty scratched up hands by the time
I was done.
One thing I really screwed up was I countersunk the holes in the
plates. Not enough material left to hold the screw heads. I had to
make new plates from sheet aluminum, matching all my holes. The
second time I used a dimple die to create the countersinks in the
plates. It shouldn't be a problem to locate the dimple dies, just
find an RV builder.
Getting the micro right isn't that bad except you can really trash the
plates when you're sanding.
I don't have any finished photos except my finished, painted airplane,
sorry.
