I am going to make a grille for my Cub 125 from round hole 18 gauge perforated sheet metal. It appears in the photos of original Cub 125 grilles that the edges are rolled over. Is this for appearance purposes, to add rigidity, or to give the grille a little stand off from the grille cowl? If it is for appearance purposes to hide the rough edges only than I may use a rubber or plastic sheet metal edge trim. I would appreciate any info/suggestions on making a grille for my 125.
