Left Flap Finished, Starting Aileron

I finished assembly of the left side flap. All the parts for the right side are prepared, but I’ll wait to assemble it until I see if I run into any fit issues with the left side.

Putting in the last few rivets
All done. I used some old 4″ vinyl post jackets to elevate the flap off the table due to the brackets on the bottom side

I started preparing the aileron structural parts next. They go through the same process as the flap structural parts – deburring, cleaning, and priming. I also took some time to smooth out the shape of the tabs on the ribs, so that they more closely match the curve of the skin. In some cases, I have to file a small notch before I can bend the tab. A before-and-after picture is shown below for aileron rib # 4. I use an adjustable crescent wrench to make these bends.

You can see how the right-most tab will bump up against the skin, and may cause it to have a bulge
Same rib after I notch the corner a little with a round file, which allows me to bend the edge of the tab, giving it a slight curve. I guess I should sand out those scratches I caused – but they’re pretty superficial.
