I fabricated the web stiffeners that go on the other side of the shorter cover support ribs. The plans don’t include the 45º cuts on the opposing flange, but I misdrilled the end holes, so I cut the flanges to remove the holes.
I primed the cover support ribs and installed the nutplates and snap bushings.
I also primed and installed the snap bushings on the web stiffeners.
Here is everything installed. The web stiffeners are riveted on the other side of the spar web under the two short cover ribs. The short cover support ribs are screwed to the nutplates installed on the web stiffeners. The longer cover support ribs are bolted through the spar bars at the top and bottom of the rib and riveted to the spar web through the middle. If you look closely, you can see that the lower rivet in these ribs is missing. I’m going to have to use my double offset rivet set to reach these and I’d rather wait until I have a riveting partner to use that.
