Left bottom wing skin done

I'm done riveting...the first wing :) The lower (forward) half was significantly easier and could be mostly done solo and in some cases even using the squeezer, but it's still significantly slower than "regular" riveting where you can see the shop head without taking pictures or using a mirror. I also saw no reason why the two outboard bays are riveted differently, so on the other wing I may just do it all the same way:

I also attached the backing plate for the Gretz Pitot mount to the skin, spar and rib:

Now on to the other wing.

Wing bottom skin riveting started

Lots of blind riveting! And by blind I'm not referring to pop rivets, unfortunately, but riveting without seeing your bucking bar. Phone cameras were infinitely helpful to see what the heck we had done:

Most of them were ok, but there were more than a few that had to be replaced, too:

Some also required a bit of contortionism to buck:

Still a ton of riveting left...

Horizontal stabilizer and elevator fairing finishing done

After a LOT of sanding and filling, I got OK results (i.e. good enough that the paint shop can fix the rest :) ) on the horizontal stabilizer and elevator fairings, and primed them:

I also riveted the bottom rudder fairing on, and now the sanding and filling for the rudder fairings will start.

Rudder cable covers

I didn't quite like the metal cover that most people use for the rudder cables - mainly, because they're too small and tight around the cable sleeve, and they're too short to stop water from getting inside the tailcone, so we used those as a rough model to make our own from fiberglass:

After cutting, the general shape was good, but the cable was still a bit too close to the aft portion in its extreme position:

so in order to be able to sand the inside of that aft portion, we added another couple layers of fiber to the outside:

Added few holes, countersunk them, adjusted the angle so the cable goes right down its center, and it sits perfectly:

After that was the usual finishing work - fill, sand, fill, sand:

Once it was smooth enough, I finally primed it (and the portion of the tailcone where it sits) and riveted it in place:
