Wing rib & rear spar deburring, trim tab assembly, wing main spar countersinking

Didn't get many pictures of this session, but there was a lot of repetitive work happening:
 
I disassembled, deburred & dimpled the trim tab, primed the mating surfaces and installed the first 2 rivets on the trim control brackets.
 
I found while deburring that I had elongated one of the trim tab skin-spar holes, and had to drill it to #30. I know paint will *mostly* hide the fact that there's a larger rivet there, but I kind of like knowing where the warts are. Here's hoping there aren't too many.
 Meanwhile Erin deburred wing ribs (mostly lightening holes), Brian Judge deburred the wing rear spars, and I finished countersinking all of the #8 screw holes in the top of the right wing main spar.
 
Empennage: 3 hrs
 
Wings: 4 hrs
