The vertical stab is complete after the skin was riveted on the skeleton. The small rivets proved quite easy to buck. I got one ding on the skin after the tool slipped, it will be masked under the paint.

Finished riveting the skeleton, the vertical stab is now ready for final assembly.

Vertical stab. skeleton assembly. The rear spar is complete, on the front spar, three rivets proved difficult, I tried to squeeze them (I shouldn't have done it)? I'll buck them tomorrow.

The vertical stab has been primed at the same time as the horizontal stab, for more information see this entry.

After I got Van's answer, I finished working on the vertical stab, only priming left.
