The ribs for both the left and right wings were prepared at the same time. Each rib was identified and layed out and then marked. I used L1-14 and R1-14 as a guide to mark the ribs for their proper location. All the ribs were prepped by deburring the edges and lightening holes, scuffed, the flanges were straightened to 90 degrees, and straightened by fluting the ribs. This was extremely tedious and time consuming. There are a lot of ribs!!
