Finished attaching elevators. Started attaching horizontal stabilizer

Fabricated a spacer block to act as a drill guide and clamped it between the horns. Double checked that the elevators were still clamped in the trailing position. Match drilled the left horn to the right horn.

Checked to make sure everything was aligned and nothing was binding. All was good. Nice and smooth through the whole range.

Positioned the horizontal stabilizer on the aft fuselage and bolted the forward spar to the attach bars. I clecoed the middle holes on the aft spar to the aft attach bars. I drilled the two top holes and installed bolts.

Unfortunately I could not get the drill squared up to the spar for the lower holes because of interference with the aft bulkhead. I’ll have to head off to home depot to get a long 1/4″ drill.
