Vertical Stabilizer - Part 1

I was finally ready to start building, and the natural part to start on (I guess everyone do that one first) is the vertical stabilizer. 

I've decided to use ATracker PRO to track time used on the different parts. So far I've used close to 14 hours. All parts are now primed. Dimpling and riveting remains.

Attaching the reinforcement plate to the front spar.

The rear spar, doubler and hinges match drilled.

Fluting is necessary to get the bar holes aligned.

The whole VS framework clecoed together. All the ribs are
fluted and flanges are adjusted to fit nicely.

Everything clecoed together.

Etching and priming

All parts deburred and ready for etching. Note that
I taped the holes in the skin to avoid that the etch would flow through
to the outside.

Etching the skin. I just sprayed the etch on and lightly scrubbed
with the scotch brite.

The skin is ready. I decided to do that one last after
all the substructure parts.

All the substructure parts hung and ready. I then pick part by part
down, spray it, and hang it back. That worked ok.

Parts marking

I had problem getting the sharpie marking to bleed through the primer consistently in the so I decided to try to punch mark part. The X is this picture below denotes the aft facing part of the VS-808PP doubler. The punched X was clearly visible after priming. So this will work fine, and can be used on internal parts to keep track of orientation and sequence of parts. I don't believe it will be necessary to mark whole part numbers this way.
