Working on the rudder, page 07-07. Step 3 instructs to final drill 2 ribs to skin. Step 5 instructs to remove the skins. Why doesn't it say to final drill the other 8 ribs and spar to skin holes? All the skin to structure holes are dimpled, but the plans only have 2 ribs final drilled. Do I follow the plans or assume that all holes should be matched drilled? I am a first time builder and have no experience. I see no reason to not final drill all holes, but my reasoning has not always served me well.
