Sporadic activity on the left wing top skin over the past week+ finally led to completion of the riveting. All back riveted once again, really happy with the results and just four drill outs over the entire wing. For this wing, I made a change to the J stiffener overlap area. There is a gap in the overlap area, I have no idea why Van’s don’t have you cut the “long” stiffener a bit longer to cover through this gap. When it is riveted, there is a slight transition visible on the top skin. I made up a shim using a spare piece of J stiffener, match drilling it from the top skin and dimpling it to nest in-between the top skin and the “short” J stiffener. Changed the rivets in this area to AN426AD3-4’s and that took care of the problem. I’m not going to bother fitting one to the right wing, not worth drilling out a bunch of rivets for that.
I installed the flap and aileron gap fairings, conduit and air lines for Pitot (green) and Angle-of-Attack (blue). The conduit and air lines fitted perfectly through the custom 3D printed nylon supports. I re-checked the pitot mast arrangement, and changed a bracket I had made to go between the mast mount and the adjacent rib so that nutplates and a couple of #6 screws are used instead of rivets. This so that it is remove-able in the off chance it ever has to be replaced in the future.
