Here's the Vertical Stabilizer ready to rivet the skin. It doesn't look much different from a previous post showing the VS skinned but a surprising amount of work goes into getting it ready to rivet on skins. You've got to match drill, deburr, dimple, clean, scuff, re-clean, prime and rivet the skeleton before you get to this stage.
Here's a picture of the inside of the VS that will be closed off after the main spar is riveted. This is another of those places where a lot of care goes into getting it right but no one will ever be able to see it except with pictures like these.
