Worked on match drilled the outboard and mid-span doublers to the rear spars. Drilled all the holes by clamping the doubler to the rear spar as a template and drilling. Also have to auger out the aileron actuator hole that goes through the rear spar. Straight forward and fun!
Clamped doubler onto the rear spar for the aileron outboard attach-next step is match drill
Match drilling mid-span doubler (same as outboard) per the plans
All holes drilled and aileron torque tube hole is drilled out (rough) w/uni-bit
