Today I finished shaping the bend relief holes on the front spars. I then cleco’d the reinforcement angles onto the spars and used some very handy yoked clamping cleco’s to hold the HS-00001 doublers in place. I’m 95% sure how I need to drill the doublers. Looks like four holes go through the flat portion of the doubler on each side. 3 holes are match drilled through the reinforcement angles and 1 hole already exists in the doubler and match drills the reinforcement angle and the spar. After the angles and the spar is bent 6 degrees, 3 additional holes are matched drilled on each side from the angles and 1 hole back through an existing hole in the doubler. I guess this is one of those types of things easier shown than described.
