Disassembled the Tail Post and deburred, primed and reassembled. Used temprary bolts becase theTail Post Channel will need to be rmoved from the assembly when the holes are updrilled theough the skin channel and piano hinge. I am wondering if it needs to be separated at the time of rivet application since there is such a tight fit,
Also today I clamped the end of the Tail Post to the Forward lower Mount Angle and drilled out the 3/16 holes in the flange of Tail Post.
