Finished the F-705 Bulkhead

Here, I've finished the big 705 bulkhead. It's the one with the lower seatbelt attachments and the upper seatback rest. It's also where the rear spar of the wing will attach.

















Coming up next are the smaller bulkheads that support the aft fuselage. They're progressively smaller hoops that define the shape of the aft fuselage toward the tail.

















Here's a handy little tip. When squeezing rivets on a flange, use a backing plate to avoid gouges. The picture below is the scrap sacrificial plate that I used on the 705 bulkhead. Thickness of .032 works about right - not so thick that the squeezer doesn't cover the rivet tail but thick enough to keep it from gouging the web.
