Trimmed aft skin flanges as needed to allow vertical stabilizer aft spar to nest in proper location. Aligned spar with laser level. Drilled 3 attach holes (one at lower end of spar, two through lower hinge point and intercostal) Decided to add a fourth attach point about 1 inch above the lower attach point. I did this just as a warm and fuzzy. The lower bolt has enough edge distance, but it was JUST enough. My spar was a bit short because of misinterpretation of one of the 8 inch dimensions on the drawings. One of the views shows the 8 inches coming from the top of the hinge....it should be from the middle of the hinge. I had made my spar slightly long to accomodate things like this....but it was just barely long enough...so I added another bolt.
