dropped plumb bobs one last time before Started riveting. Honestly don't know what I would have done if it had magically been off this time, because everything is already match drilled and dimpled. Fortunately, it wasn't an issue. Still dead on.

Ran into a clearance issue where the flange of the F-712 was riding up on the flange of the F-779 on the left side. I didn't want to take this all apart again, so I was able to take enough clecoes out to get in there with a jewelers file and open it up. Hit the raw edges with primer on a q-tip and everything good.

Started riveting. The plans say start by riveting F-712 to F-779. At this point, I kind of think that meant do that first and then install both of them into the main assy. I already had everything clecoed together and it was fitting so good I didn't want to take it apart again. I went to my arsenal of bucking bars and thought I could probably buck all the rivets in the F-711 & 712 without taking anything back apart around the Wd-409 weldment. I was able to get all of them except the two closest to the bottom of the weldment, and it was so tight in there I was afraid I might botch something trying to buck those, so I decided to just use MK-316-BS rivets in those two locations.

One of the J- channels had a couple of holes between F-711 & f-712 with questionable ED. Was shy by around 1/32" probably stupid to worry about such a tiny deviation, but it was an easy fix, so I went ahead and match drilled a doubler. Doubler covers 5 holes and gets me my edge distance.


Other than that, I just started riveting from the back fwd.
