The last few days have been full of skeleton work and skin match drilling. I am deviating from the directions a bit mainly because I don't have time to prime right now, but I went ahead and match drilled the skins onto the Skeleton without riveting the stiffeners first. I think overall it takes more time, but it can be done with shorter work sessions. To Prime takes a lot of prep work. If this works correctly I will be able to prime the whole rudder at once which will save time in the long run. See that I have the stiffeners installed with Clecos, so the entire rudder can be held together for Match Drilling. The rudder skin is so thin, almost like aluminum foil. You need to be careful here.
