Cont'd Sect 10-27 at Step 5 & 6: Match drilled 2 angles, then deburred all holes. Primed all pieces for Aft Deck assembly. Started rivets Step 7 - significant variety of sizes and types in one area needing numerous tool set-ups. Challenging to determine best approach, but trial and error is working, combined w/ prior experience on what works well, etc. All these pieces and rivets are critical since this is where Horiz Stab and Vert Stab attach...lots of loading !
Also jumped ahead to Sect 10-32 to build the rear Access Cover Plates. Deburred all edges and holes, then used #6 screw size dimple dies to create recess for flush machine screws per the Optional arrangement. I "broke" the edges with the roller tool to insure Plates lay tight to fuselage skins. Glad I chose the Optional, even though under HS, it's "slicker" with flush screw heads.
