More work on the ribs tonight.
The rib process starts with deburring everything which I did a few days ago and posted in earlier posts.. Then you use hand seamers to get the flanges 90 degrees to the Web (the part with holes). Once you get them exactly 90 degrees, the whole rib is bent because of the forces within the metal..
To straighten out the rib you use fluting pliers and leave little dents between the rivet holes. This pulls the rib back into line.
Here is a stack of completed ribs next to a stack of ribs still to do. Hopefully you can tell the difference because there is a lot of work that goes into this.. ;-)
The total number of ribs in an RV for both wings is below:
-12 Outboard nose ribs
-14 Tank nose ribs
-28 Various main ribs
That's a lot of ribs
