Positioned, pilot drilled and clecoed SNX-F23-04 aft lower mount angle to left and right lower longerons.
Getting good contact with the longerons caused a minor separation to open between the angle and the lower vertical fin spar. If pulled in to make good contact with lower mount angle (like will happen when the bolts are installed), the out spar flanges flex inward and loose the 2.50" outer gap separation specified. Made a spacer from 0.026" 6061 T6 aluminum sheet material (cutoff scrap from making the tail control surfaces) to fit between the aft lower mount angle and the lower vertical fin spar. This filled the gap, and eliminated the flexing inward of the spar's outer flanges, maintaining the 2.50" gap specified.
Positioned tail skid tube mount on lower vertical fin spar to drill pilot holes in larger skid tube holder mounting plate. Used a 12" flexible 1/8" drill bit to get around the extended mounting tube on the assembly and drill 4 of the 6 pilot holes. Will have to wait until the new tight fit right-angle drill head arrives tomorrow to get in to drill the last two pilot holes due to the obstruction from the tube.
SNX-F23-04 aft lower mount angle ready to be pilot drilled to lower longerons.
Skid plate mounting tube lined up and pilot drilled to lower vertical fin spar.
0.026" 6061 T6 spacer to fill gap between aft lower mount angle and lower vertical fin spar.
