After a week of working for a living, I was able today to get back to the project. I trimmed the L/E ribs in the hope they don't produce a bulge when the skin is riveted in place, thank you PGC & Bob Z for the hint. One rib in particular (#107) is also very low at the spar so I manufactured & alodined a spacer that hopefully will make the skin fit a lot better. I'll paint it tonight with hopefully a trial fit of the skin tomorrow.
