Center Section Drilling; Control Assembly Bracket
This is where the close-tolerance bolts spent the night -- in hopes that they would go in easier...yeah....whatever.
I managed to get them in enough to get the vertical pieces of the center bulkhead aligned so that I could match-drill them to the horizontals. Here you also see the spacers that go on the inside. It's clamped in so that I can drill through them for the AN470AD4 rivets that hold 'em on.
Here's the top view. You can the AN4 bolts resting in there that go through the spacers.
Next I started working on the control assembly brackets. These things will get bolted to the center section web and hold the entire stick assembly -- very critical. Note the bearings in there. I have no idea how those are in there...there are no visible fasteners...I guess they're glued in there....who knows?
These things get trimmed for weight savings so I measured and marked off the areas that will get removed.
...then I started cutting...but it was getting late and the band saw is way too loud. Until tomorrow...
You know, I'm not getting much done these last few days, but I suppose that any work is better than nothing...
