I finished up deburring and dimpling the firewall. I moved on to the aft fuselage section, prepping the F-706 bulkhead and then the skins. I removed the corner ribs and trimmed a little off of the aft end so it would clear the flange of the F-706. I also deburred the corner ribs. I removed the outer seat ribs and started deburring them.
I realized that I was over-zealous in my counter-sinking over the weekend. The ends of the forward floor stiffeners that overlap the F-704 flange should be left alone, but I countersunk them. On the plans, it says to countersink the skin where those stiffeners overlap the flange, and I had forgotten that I already did that. If I can’t figure out a way to fill in the countersinks with epoxy, I guess I’ll have to order new parts. Not a big deal, but annoying.
What I should have done while disassembling the fuselage was to mark where countersinks are needed on each part one by one. I just took everything apart, and then it’s hard to visualize what goes where and what needs dimpling or countersinking.
