Brief Description: Aft Fuselage - Riveting
|
|
Before beginning riveting, I had a nagging feeling that I needed to first check the plans closely. That feeling paid off! First, I noticed that the last two rivets in the lower J-stringer where it intersects the F-712 bulkhead, plus the two rivets just above those, will be used to secure the rudder stop. Since the rudder stop is material thick enough to be countersunk, the holes in the skin, bulkhead, and J-stringer do not have to be dimpled. I had not dimpled the bulkhead, but I had dimpled the skin and J-stringer, the latter of which caused the stringer to stand proud. I had to completely uncleco the stringer, and uncleco the bulkheads from the side skins to loosen the stringer enough to pull it back enough to flatten the dimples. A little tedious, but worth it.
The second thing I noticed that I hadn't yet accomplished was drilling and dimpling the holes for the #8 screws for Adel clamps that secure rudder cable guides just forward of where they exit the fuselage (photo 1). I had to completely uncleco the F-710 bulkhead to get my dimple die bucking bar square to the skin, but it sure beat having to completely remove the side skins for dimpling in the DRDT-2.
After taking care of those two oversights, I got the aft fuselage completely riveted up to but not including the F-710 bulkhead (photo 3). The instructions have you not rivet above the upper J-stringer so the side skin can be pulled back for dimpling after drilling the main longerons.
Rivets Today: 94
Rivets Total: 9157

Almost missed dimpling this hole...

A good start on riveting the aft fuselage.
