Trimmed, scuffed and glued the R wing -17/18 doublers. Sanded the upper edges of the L wing doublers even with the spar surface in preparation for the ply caps. Used the Makita arm sander for the heavier sanding and a file for finishing. Bobby and I flipped it before calling it a night so I can sand the bottom edges next. Also, I used blue painter's tape along the edge of the soft spar as a reference point when power sanding. This thing will chew through Douglas Fir in a flash if one is not careful.
