1.5 hrs working on the VS.  Continuing work on the top rib for the VOR antenna install.

Taped off around the antenna so I know where on the skin to cut the exit hole.

Just got these precision files today - just in time for the fine-tuning of the holes in the flanges of the rib.  I added a new tag word, "tools" for any tool related posts.

Here's the taped-off hole and the drilled and filed hole for the hex key (where the line is drawn vertically so I knew where the pilot hole would be drilled).

The hex key fits!
