Brief Description: Fab RH J-Stiffeners & Match Drill LH Upper Flange
I decided to fabricate the RHS J-stiffeners so I can close out those steps for each side. They got labeled after deburring the edges for the match drilling step later.
On the LHS I clamped the appropriate J-stiffeners in place, taking care to overlap them properly and set the 1/16 inch overhang. Before I started drilling I reviewed the plans to make sure I understood the big picture.
In general, each hole on the spar flanges will get countersunk. Some holes will be C/S flush and some will be C/S 0.007 inch under flush. Holes with screws will be C/S based on diameter and not depth. It took a call to Vans before I finally understood everything.
I managed to finish the LHS upper flange match drilling of the aft holes and the J-stiffeners. I was pretty tired so I decided to deburr the holes tomorrow.
