The hinge brackets get riveted to the rear spar using AN470AD4-5 rivets. The blue tape is placed on the holes that do not get rivets just yet.
I used the 2x rivet gun to set the rivets has the rivets are to hard to squeeze. The only problem is that two of the rivets did not set well and had to be drilled out and replaced. Using a #30 drill bit and snapping the head off works well for this size rivet.
Working down the rear spar, the spar doubler gets riveted to the rear spar using mostly 4-6 rivets. Again, the blue tape is there to keep me from placing rivets in those holes at this time. The tungsten bucking bar makes the riveting process much better then a ordinary steel bar.
