I finished deburring the edges of the skins today. I still haven't decided if I'm going to prime them all ahead of time or not, but at least the edges are done when I do.
The two bases of the control sticks get bolted to the aft center section. They come as some angle with a bearing pressed in. I located and drilled the top bolt hole and marked out the areas that can be cut out of the base (for weight savings - every little bit helps).
The two bases (one for the left stick and one for the right stick) were bolted to the aft center section and then clamped at a right angle to the top flange. Then I drilled the second bolt hole at the bottom of the angle using the pre-drilled hole in the center section as a guide.
I contemplated not bothering to cut out the "weight savings" portion, but in the end decided I might as well.
The next step was to take the left and right sticks and trim the bearing surfaces to create a slip fit into the connecting arm that goes between the left and right sticks. I ended up having to take off a good 1/16" of the bearing and about the same of the steel itself. I'll bolt everything together and take a picture later - it'll make more sense then. I'm waiting on the primer to dry on the aluminum angle bases before I put it all together.
The top flanges of the center sections get a bunch of nutplates (I'm not sure what for, but I'm assuming the seat pans?), so I countersunk all of the nuplate rivet holes and installed the nutplates.
