Mid Fuse Ribs & Bottom Skins 26-5-9 to 26-5-11, 26-6-7 to 26-6-9, 26-7-4

To alodine the COM antenna doublers and spacers, I have been using Bonderite Alumiprep 33 for surface cleaning and Alodine 1201 for alodining. These are fairly easy to work with, however due to their toxicity I did take additional precautions by working outside, and to ensure that I didn't accidentally splash any chemicals on myself I wore goggles, gloves, long sleeves, and a respirator.

Parts were dipped in a 5:1 solution of Alumiprep for about 5 minutes, then rinsed and dipped into a 3:1 solution of Alodine for another 5 minutes

After a final rinsing and drying, both sets of doublers and spacers were a similar color to my RV-10 wing spars

After clecoing the spacers and doublers back into their respective rib bays, all that was left now to complete this section was to rivet the bottom skins to the rib and spar flanges. My daughter helped me with riveting (as she had done on the wing top skins) and slowly the clecoes started to disappear.

Starting in the center of the forward bottom skin, we riveted outwards

Once again, I'm very happy with how flat the rivets and skins look using the Boeing flush set
