Started working on the F-715 seat ribs - 2 hours

Still working away on the nutplates. Finished drilling the standard nutplates. The two nutplates on each side of the F-705 bulkhead need one-legged nutplates. I decided i'll finish those later..I'm a bit eager to get working on the seat ribs.


I then measured the F-715 seat ribs for center.
 

More nutplates - 2.5 hours

So one of the items that I missed was to drill the nut-plates in the flange of the F-705 bulkhead. Like the other nutplates, I used a sacrificial nut-plate to drill the needed holes. Unfortunately since the bulkhead is already primed, I didn't want to draw a center line so I had to line each one up individually. Took a little time to get it all lined up.
