My buddy Jeff had a few minutes to help me out tonight, so we were able to finish riveting the remaining Wing Ribs. We riveted Wing Ribs #4 - #11 to the Right Wing Main Spar using AN470AD4-7 universal rivets. We used a 3X rivet gun and tungsten bucking bar to complete the rivet installation.
This is the forward side of the Right Main Spar looking from inboard to outboard. You can see the vertical rows of shop heads of the installed rivets.
The is the opposite end of the Right Main Spar looking outboard to inboard. You can also see the vertical rows of shop heads.
Finally, this is a small section of the Right Main Spar between Wing Ribs #9 and #10. From this view, you can see the 10 manufactured heads of the installed rivets (5 on each Wing Rib).
After riveting all the Wing Ribs (except #14, as directed by the plans), I finished the prep work on the Right Rear Spar. I deburred the holes previously drilled for the Spar Doublers and cleaned all the edges. The next step is to dimple the upper and lower Flanges of the Right Rear Spar. Then, the Rear Spar and associated parts can be Alodined and Akzo primed.
