Fitting the F-7112 Aft top skin - 3 hours

 I spent some time tonight tweaking the fluting on the F-707/F-708 and F-709 bulkheads to ensure the best fit possible. I now have every hole clecoed and checking the flange on the inside, the fit is very good.

 

I am ready to fit the F-7112 top skin. Like the rear top skin I really need to adjust the fluting on the F-706 bulkhead to get all the holes to align. Since the fit at the top is really good. I match drilled the J-stiffener. However I need to trim the forward end a bit as it appears that there is interference with the bulkhead.
