Removed strips of vinyl material near holes only to minimize scratching. Clecoed skin to vertical stabilizer skeleton. I noticed there small dents appeared where the skin touches the VS-1005, VS-1013 and VS-1006 ribs. Looked online and found this be a common problem. Other people have trimmed some material from these ribs to prevent the problem. I trimmed some material from the ribs even though the dents are minimal.
Final drilled all of the skin hole common to the skeleton. Removed skin and dimpled holes per plans. Used DRDT-2 for all inside holes. Used pneumatic squeezer for all edge hole. The DRDT-2 cannot reach the inside holes closest to the leading edge. Used dimple block set and rivet gun to get these two holes.
Getting close to the riveting stage, so will need to order primer and painting equipment soon than later.
