I have been delayed getting started on my project so I decided to do another practice rudder project before jumping in to the empennage. Step 6 says to cleco the skins to the skeleton. Sounds simple enough... Both parts are pre-punched, however, the holes are not even close to lining up between the two parts. The skins have 7 holes over the same span as the rib which has 6 holes. The stiffeners lined up just fine. What am I missing? You can see the two rows of holes in the pic (red arrows). I don't remember this issue in my first project almost a year ago (which I no longer have).
