Trimmed more Nose Ribs and did a lot more deburring and sanding. Fluted the Nose Ribs but I found it difficult, if not impossible, to straighten/flatten them. Dimpled some of the Ribs and nutplates per plans. Primed the 3 Nose Ribs that were dimpled. Match drilled 2 Main Ribs per page 15-03. Will install the nutplates tomorrow.
