Page 7-12; Drilled the skins and tips to size for the 6R6 screws. Dimpled the skin for both wings and machine countersunk the fiberglass for the left wingtip. Installed the VOR antenna in the left wingtip. I used 1" strips of fiberglass to bond the outboard end of the antenna to the tip. Except for the nutplates used for the gounding edge of the antenna I am using clickbond nutplates for the remainder of the mounting screws used in the tip
