Method for epoxy application control overpresses

A method for placing a resin layer on a selected surface, the method comprising the steps of:

• (a) providing an overpress having an inner surface and one or more lateral edges, the overpress further having a plurality of nubs protruding from the inner surface of the overpress, the nubs located at the lateral edges;
• (b) placing liquid resin on the inner surface of the overpress;
• (c) forcing the nubs of the overpress in contact with the selected surface of the frame member using a plurality of clamps, the nubs defining a clearance between the overpress and the frame member;
• and
• (d) after the liquid resin has cured, removing the overpress from the selected surface of the frame member, thereby, leaving a layer of cured resin bound to the selected surface of the frame member.

A method of attaching a skin to a frame member of an aircraft, the method comprising the steps of:

• (a) providing an overpress having an inner surface with a plurality of nubs protruding therefrom at a uniform distance from the inner surface;
• (b) placing a bead of liquid resin on the inner surface of the overpress;
• (c) clamping the nubs of the overpress in contact with the selected surface of the frame member, the nubs defining a clearance between the overpress and the frame member into which the bead of liquid resin spreads;
• (d) allowing the liquid resin to cure, then removing the overpress from the selected surface of the frame member, thereby leaving a layer of cured resin bound to the selected surface of the frame member;
• and
• (f) attaching the skin to the frame member of the aircraft, the layer of cured resin being between the skin and the frame member.
