I unpackaged the wing ribs 008 Left & Right kit, used scotch bright and alcohol for prep, primed, assembled and then riveted the assemblies.
My kit didn't contain a 011L hinge bracket, but had another 014L instead used on wing rib 009. They are practically identical except for a few hole locations so I clamped it back to back with the 011R bracket and re-drilled the holes. I riveted washers to two of the hole for greater surface area an the back side. The inside corners are only half-holes with a miter, so the washer just keeps the bracket flat.
