Continued working on the main emp fairing. 1st order of business is to get it clamped on the Horiz & vert so fits as close as possible, Match drill #40 to the holes in the horiz & Vert. Cleco. I had erronerously riveted the aftmost rivet on the rop tailcone skin along the longerons. This ends up getting eventually tapped for a #6, So I drilled out the rivets on both sides. Marked the fairing per plans , then removed it and used a cutoff wheel and some #80 grit to get it to 'final' shape/contour. The plans say that the opening in the rear where the Elevator horns travel through needed to be marked and trimmed to allow min of 1/4" clearance through full travel. so I remounted the Elevators, It turned out that it wasn't totally necessary and the opening was plenty big enough. Although there is a small portion of the right close-out 'rib' that requires some trimming to avoid interference with the right elevator in the full down position. Reattached the fairings , and then final drilled all the Vert & Horiz holes to #27, (and clecoed w/ #30's). Then carefully countersunk (#6 aka 27) the fiberglass on all of the #27 holes in the fairing. Then removed the fairing again, and used a #6 nutplate w/ Screw inserted, and a cleco clamp, to hold and drill all of the #27 holes for nutplate attachments, deburred the holes and thenI began to dimple the nutplate rivet holes. ran out of time for today, so tomorrow, I'll continue, I may need to dissassemble at least the Vert stab in order to dimple and rivet all of the nutplates. Additionally the holes along th ebottom close out rib, get drilled and tapped for a #6 screw and that might require removal of the Horiz Stab & elevator.
