Center fuselage: ribs and floor skin

TLDR

• Installed ribs to main/rear spars
• Rivnuts on various channels
• Started on bottom front floor skin

Ribs on spars

Took a while to complete, mainly due to access. The space between ribs were pretty small so I moved slowly using a hand riveter.Œ

Rivnuts

Before bottom floor skin, the instruction wants me to install a bunch of rivnuts on channels, skins, etc. So I did that.

It’s a little difficult to visualize what they are for. I assume they are for the center console area.

Bottom floor

Then I prepared the bottom skin and its strengthening channels.

I also filled the rivets using superfil while I still have easy access.
