I took the time tonight to identify and mark all wing ribs. This was a surprisingly time-consuming process because there are three types on main ribs (on the left) and four types of leading edge ribs (on the right), and all of these come in left-handed and right-handed variants. Also, each wing has a mix of the left and right-handed variants and they don’t follow any simple pattern. Basically, you have to study the plans and make sure you’re using the right rib in the right spot. I have all of these stamped now, and I’ve double checked them, so it will be easy when it comes time to attach these to the spar.
