Hello everyone, I've got a slow build wing question. Sketch 36 in the plans only shows one line of rivets where the two bottom wing skins join together at the rib. All the other RVs have two rows of rivets, and there is enough skin to provide the second row. If the second row was needed I would assume it would have been updated on the 3-B plans, but it still shows 1 row. Any suggestions? I don't want to do extra work if it not needed. Thanks
