Tonight's work was mostly riveting together the multiple pieces that form some of the ribs, nose ribs, and hinge brackets of the ailerons. All of these rivets were flush rivets that I had to prepare with the countersink drill cage. A couple of the pieces also required a nutplate to be riveted on as well. All of the riveting done tonight was just done with my hand squeezer. Prior to riveting all of these pieces, I spray painted a little more primer on these parts for corrosion prevention.

Although this primer dries to the touch pretty quickly (about 15 minutes), it unfortunately is still pretty soft for at least a full day so it easy to accidentally scratch or stick to other contacting surfaces for that period. I'll try to leave freshly primed parts overnight before doing their next steps, but that isn't always the most convenient for keeping up progress.

I also had some time to prep to prep the aileron spars by dimpling the flanges where the skins will go, deburring the lightening holes and edges, scuffing the surfaces with a scotch-brite pad, and applying some primer.

What's next? It looks like I'll be mock-assembling the aileron spar, nose ribs, and drilling the stainless steel counterbalance tubes.
