Well, it turns out that the elevator/horizontal stabalizer hinges were installed incorrectly. Because the hinges were fabricated in my airplane factory, they were each unique; very similar, but unique. When the hinges are assembled correctly so that the hinge line is above the HS, the hinge holes in the HS no longer line up. Not a big deal, just a quick repair. I filled the holes with flox and will redrill tomorrow when the flox has set.
Tape below so flox doesn't drip
All done in 30 minutes. Nothing to see here. Move along!
