Horizontal Stabilizer - Deburring and prep

I ordered a long drill bit so that I can attach the center hinge gusset and center hinge bracket with straight, perpendicular holes. In the meantime while waiting for that to arrive, I took everything apart, deburred, and scrubbed the mating surfaces with scotch-brite while watching the Cubs pull off a miracle.

When the drill arrives I’ll finish the rear bracket, widen the holes, debur it, then apply Cortec to all the mating surfaces.
