I primed and assemblied the baggage bulkhead a couple of weeks ago..
The upper wear blocks for the shoulder cable gets riveted to the upper bulkhead with the square washers and pop rivets.
Then I dimpled the nutplate rivet holes in the lower bulkhead.
I have also dimpled the nutplates, I like this method much better than countersinking the skin..
Then I riveted on the lower wearblocks..
Last thing I did was rivet on the longeron gussets.
The forward ones get dimpled where they gets riveted to the F-706 bulkhead.
