I started the day riveting on the nut plates to the F-782B and F-783B supports. I used the NAS1097 rivets as the supports are thin material. I also installed the nut plates on the F-704M stiffeners however I used the AN426AD3 rivets on those as the material is much thicker.
Next I began to rivet the supports on the center section. I haven't bucked rivets with a bar in quite some time so I was a tad nervous about this.
I used a 2x4 clamped to the workbench as a bar support. The rivets turned out extremely well, and I soon regained my confidence with bucking.
All done the supports.
Next I needed to rivet the center section sides. I was concerned about the side moving with riveting so I greased up all 4 close tolerance bolts and inserted them into the center section. I then cleco'd all the holes and then began to squeeze the rivets.
After a few, I just found squeezing them a pain, so I opted back to the gun and bar. The riveting went extremely well and quick. Drilled out only 2 rivets I think. I have to say I am beginning to really love bucking (Thanks to the endless bucking of the wing skins....a person gets really good at it).
Center section riveting all done.
