Fuselage - Center Section
Drilled F-715L and the four F-623A attach straps. Deburred the holes in the baggage ribs and cleco'd them on to the F-705 bulkhead and the F-776 skin.
|Decided that I better drill the F-623A FWD and AFT attach straps. This is the FWD strap being drilled.|
|FWD strap drilled and cleco'd on.|
|Here's the AFT strap. I wasn't quite sure which hole this went to at the AFT end, but the plans are pretty clear, if you look close enough.|
|AFT strap drilled and cleco'd on.|
|Forgot to drill the holes in the FWD edge of the F-715 ribs. So, cleco on F-704H and drill.|
|I went ahead and countersunk the holes for the nutplates in the baggage ribs. Easier to do now, on the bench, than later, after the center section is installed.|
|Removed all of the baggage ribs and deburred the holes that were match-drilled to the baggage skins. Ready to do final install on the baggage ribs.|
| Final check before we rivet on these baggage ribs. Make sure that the holes for the snap bushings have been drilled. One more thing, I made sure that all of the bottom holes in the ribs were dimpled, as well as all of the holes in the F-776 skin (remember that big ugly pop rivet in the seat ribs).|
After this was taken, I had to remove all of the ribs again, because it appears that they had not been match-drilled to the seat ribs and the F-705 bulkhead. Once the F-776 skin is on, it is hard to match-drill these ribs, so make sure that you do this way back when.
