Hi, I am new to this site. I am currently finishing my wings for an RV-9A and have received my fuselage kit. Until recently I was unaware of this forum since I don't like to spend to much time on the computer. With family, work and a slow internet connection, I need all the time I can get to build. Looking at the previous threads posted it is amazing how many questions, problems, etc, are exactly the same I had during those stages of building. I can see what a very useful tool this forum is. My sincere gratitude to those who have the ability and are willing to take the time to document there progress on the internet.
I am almost ready to rivet my bottom skins on and am curious what others have done with the holes for the wing root fairings in the wing structure. Eight of the holes in the W-902 top skin call out to be machine countersunk. I suspect this is because the material thickness in this area is sufficient due to the skin, doubler and rib. The holes that will eventually be drilled in the T-901 tank skin for the fairing I assume will be dimpled. What about the remaining holes in the W-904 bottom skin and the top skin at the flap gap fairing. Should I drill and dimple these now for the #8 screw while the pieces are seperated or wait and locate root fairing and then dimple both skin and rib and skin and fairing together. My concern is, dimpling when they are together will be over .040" and you will be dimpling two pieces at the same time. Thanks!
