Mar 28, 2024 6 HS drill and install. Category: Fuselage
Time to position and install the horizontal stabilizer. First I made the spacers that go under the front spar angle of the HS. Next was to position the stabilizer so it is equal, side to side and there is no sweep. Basically equal to the longitudinal line of the aircraft. With some careful measurements and the HS clamped in place, I drilled the outboard holes, which are very critical as they go through both supporting angles and the longerons, all of which must be centered with proper edge distance. Pilot hole to #40 first then upsize slowly from there. Since I measured carefully, the edge distance was great and I'm happy with the outcome.

Next was to slide the spacers under the front HS spar, align them and dril the holes through them. Bolt this down. Next slide 3/16 spacers under the center of the rear HS spar and drill through the thick bars at the rear. I was able to eyeball the center here and it turned out great. Put some keeper bolts in there.
Next to drill the inboard holes in the front HS spar. The measurements are on the plans.
