All of the 160 ribs are now routed to shape and ready to form. Nearly all of the .025 nose, center, and tip ribs have had lightening holes pressed. On of the spare nose ribs was pressed and finished with the flow-forming head on the #4 rivet gun with OK results, but moved to press for just the lightening holes and full flow forming on the main ribs. One of the Sta. 11-14 center ribs was done this way and is aircraft quality.
