Brief Description: Almost finished with center spar mods
Tonight I back-drilled the two outer uprights on the back half of the center spar. These line up with the dual stick uprights that were previously in place on the front half. I then drilled 40mm pitch #20 holes through the top of the front half top doubler. At this point I was cold and tired, so I left one small job to be done in my next session. I just need to put shims behind the dual stick uprights. Those were not originally required.
