Surely the only way that an eccentric lift pin can be used to adjust
wing incidence is if it it done before the spars are bored for the

Sorry, I am both reading comprehension *and* math challenged today it
seems (I have a medical excuse, it's temporary, fortunately!).

The clearance on the main pins I don't know. I'd guess it's around
0.003" judging by feel, but that's a guess, I've never paid too much
attention. The change in clearance due to an incidence offset is easy
to calculate though, and it's about 0.0005" total on the depth of the
center spar stub for a 1mm offset pin. Those are all armchair
numbers, but the conclusion (supported by experience) is "No Problem".
