Brief Description: Position and Drill bottom of Horiz Stab skin
The holes in the pre-drilled skins were carefully aligned with the rivet lines on the spars and ribs. I had to file the slots in the skin for the forward attachment brackets in order to get the skin to line up with the rear spar.
The spar spacing is greater in the center of the spars than at the end because of the thickness of the doublers (6T1-5HD and 6T1-7HD) on the spars. The dimensions of all the ribs are the same, so the ends of the spars are about 2mm closer to each other than at the center of the spars.
