Today, I finished the dimpling of center fuselage, the only part remaining was the lower skin.

After the center fuse, I did the dimpling on the rear fuselage. The upper rivet line is done, the lower one remains to be done as it is unreachable with the squeezer.

Today, I begun dimpling the center fuselage parts. I did all the holes I could reach with the pneumatic squeezer, this leaves all the holes on reachable with the C-frame to be done.
Then I removed the small tags bearing the parts number, when there is no blue plastic, the tag is glued to the aluminum and a pain to remove.

Today I ended the deburring of the center fuselage parts. I also countersunk the rivet holes for all the nutplates (the countersink is very light as I will be using some small "oops" rivets that have a smaller head).
I also decide against using screws to fasten teh baggage area floor, sticking with pop rivets will avoid installing lots of nutplates. Here are some of the parts that will now have to be dimpled.



I then finished preparing the double flush rivet line on the main bulkhead, this is due to the fact that the main gear support will be installed on the outer part of the bulkhead. The bulkhead gets countersunk using the angle drill and the countersink bit without the cage, going slowly and carefully is the trick here.

Still in the deburring phase. I also modified two more ribs to allow for an easier installation of controls. I then drilled the crotch strap support for installation of nutplates.
I still have some deburring to do before beginning the dimpling.
