Riveted the upper cross angle to the aft spar box. Looked at the print, and it needs to be riveted to do the spar drilling (can't have clecoes inside the spar box). Riveted on the control triangle support angles then noticed that the upper end of these don't have any fasteners. Looked back at the F16 print and no fasteners are called out, but on F01 they are. They are actually left undrilled for the trigear gear leg mount brackets, but for a taildragger (what I'm doing here), they just need some more rivets at the top end. No dimensions are shown for these - I could assume the taildragger gear leg mount bracket dimensions, but continuing the row of rivets spaced at 1/2" works fine. So I drilled these angles back off the aft spar box and drilled the additional holes, deburred, and dimpled the spar box. Still need to countersink the F16-06's and rivet them back on.
