(8-5 step 4):
Tonight Angela was right back out in the garage and back to
work. Here she's match drilling all the holes in the in the front
spar to the attachcment brackets. These will be used to attach
the front part of the horizontal stabilizer to the rest of the airplane.

Here's a pic of the brackets after the spar has been turned over…

(8-5 step 5):
Once the brackets were done, then came all the holes common to
the doubler and the spar. After that, then she got to final drill
the 4 "big" holes. I haven't measured it, but the aluminum
stackup through this area is pretty thick!

(8-5 step 7):
The final thing Angela did for the night was final drill &
then countersink the middle 9 holes in the spar flanges. This is
where everything comes together at the tail of the aircraft.
