Temporarily assembled the horizontal stabiliser, attaching the nose ribs and internal structure to skins so I can verify which holes need to be upsized and dimpled for the larger rivets. Very impressed by the way it all fits together, once the first few clecos were in, all the rest went in very easily and it sits on the bench with about half the clecos. Started removing the vinyl around the rivets so the outside of the skin can be deburred and primed prior to dimpling.
