Carrying on with the F-704 bulkhead the next job on the list is to fit the nutplates to the top of the gold spars. To do that first I needed to enlarge the prepunched holes and then countersink all the holes that will be taking a rivet.
After that there are 4 ribs that need to have the prepunched holes enlarged enough to be able to fit grommets for plumbing and wiring. So I enlarged the holes and then cleco’d the ribs to the spar then match drilled all the holes. I then fabricated two stiffners as per the plans and match drilled that too.
That’s it for today.
