January 20, 2006 - F-704 Bulkhead |
||||||
| The instructions never really tell you when to do what to the main F-704 bulkhead. This is the last time I'll have easy access to it so I decided to take care of it now. There are twelve empty holes on the forward bulkhead side that I fastened with AN4-12a bolts. | ||||||
 |
||||||
|
I combed over the center section making sure I didn't miss anything.
|
||||||
 |
||||||
| The 12 AN4-12a nuts after torqueing. . | ||||||
 |
||||||
|
Then I bolted on the control support brackets. I'll just use blind
rivets on the bottom skin where the brackets block bucking bar access.
|
||||||
 |
||||||
| Then I inserted and torqued the two AN4-32a bolts and their 1 7/16" spacers. The F-704 bulkhead is pretty much ready to go. | ||||||
 |
||||||
| Next I turned my attention to the center fuse corner rib and seat side ribs. Although you can't see it, I inserted the spacer block between the aft wing spar "fork" and put an AN-3 bolt through the side rib, fork, spacer block and F-705 rib. | ||||||
 |
||||||
| The view from th eother side. You can see the end of the AN-3 bolt sticking out. | ||||||
 |
||||||
|
The final accomplishment of the day was to cleco the center fuse section
to the aft fuse and put the main longerons back on.
