Time: 5 Hours
The center section has a forward half and an aft half that will eventually be joined to make a pocket for the wing spars. On each side there are 2 bulkheads one forward and aft. I deburred the edges and all the holes in each of them. On the left side there are several nutplates that needed countersinking as well. I got that work done yesterday after a pretty good day of house hunting. My girl, which works for the same company, got the approval to transfer to Chicago! So we are pretty excited to get a new and larger home to share together. A lot if nice houses out there, my wish list….a large garage for the aircraft build. Hers….nice kitchen and master bath. We found a few and hope to make an offer soon. So today I got back at the center section. First was to prime and paint the 4 side bulkheads.
Several other parts get riveted to the center section including the forward seat supports and seat ramp supports. I match drilled all the holes and enlarged the ones that will have a AN3 bolt in them.
There will be one rivet that holds the side bulkheads in place that will interfere with these vertical supports. So you need to countersink it so that you can put a flush rivet there so the support will sit flush on top of it.
Since I’m going to have to wait several days before riveting these parts as the paint drys I looked aged in the plans for the next steps. The next phase will be the seat rib assembly section. So I spent some time looking for and locating every part for this substructure in between primer coats on the other parts.
