Horizontal Stabilizer Rear Spar

Started work on the horizontal stabilizer today. The first part involves preparing the rear spar.

Deburred the rear spar and the rear spar doubler with the Scotch Brite wheel, files, a deburring tool and god old fashioned sandpaper. Got all the edges and lightening holes nice and smooth. Clecoed the rear spar doubler to the rear spar. Final drilled all the holes.

Clecoed the 8  outboard hinge brackets to the spar and final drilled.

Machine countersunk the two holes in the center of the spar.

Fit, clecoed, drilled, disassembled, deburred, reassembled, and riveted the inboard hinge bracket assembly with the flange bearing in the middle.

Deburred and scuffed everything. Ready for primer. I’m only going to prime the inside of the spar. the outside will be painted when I paint the airplane. I neglected to account for this when I built the VS and rudder. I’m assuming the primer can be stripped from the outside of those spars in preparation for painting.
