Enlarged the snap bushing holes. Much consternation about edge distance on the 5/8″ holes in the spar, but it’s just for snap bushings, so I guess Vans knows what they’re doing.
Fabricated/trimmed/deburred the hat stiffeners, and a pile of seat brackets.
Riveted some seat brackets together, and installed a mess of nut plates.
Berck: 6 hours
