1. A method for producing a custom sized canvas stretcher frame comprising:
selecting four perimeter members, each such perimeter member including an inside edge, and outside edge, a front surface, a back surface, two ends, a longitudinal axis and a total length as measured from one end of the perimeter member to an opposite end, the perimeter member including at least one corner tine receiving channel running longitudinally along the total length of the perimeter member, the at least one corner tine receiving channel demonstrating a uniform and continuous cross sectional size, shape and configuration especially designed and adapted to matingly engage a perimeter retaining tine, each perimeter member further including a mounting material retaining channel extending along and demonstrating a continuous opening upon the back surface of the perimeter member and along the total length thereof, said material retaining channel demonstrating a continuous and uniform cross sectional size, shape and configuration especially designed and adapted to receive and securely contain a length of mounting material therein and wherein each perimeter member additionally including a cross bar mounting block channel running longitudinally along the total length of the perimeter member adjacent to, and presenting a continuous opening along the inside edge of the total length of each perimeter member and demonstrating a uniform and continuous cross sectional size, shape and configuration, the cross bar mounting channel being especially designed and adapted for the mounting and retention of a cross bar mounting block; determining a required length of each of the four perimeter members necessary in order to provide a stretcher frame of a desired perimeter measurement; cutting the perimeter members as required in order to attain four perimeter members of the required length thereof; selecting four corner members, each being comprised of two corner sections and an adjustment key, each corner section including a front surface, a back surface, an inner edge, an outer edge, a 45 degree end and a 90 degree end, wherein, each of the 45 degree ends of the corner sections is mortised to include at least one corner section tine receiving slot and at least one corner section tine which are so formed, arranged and positioned so that the 45 degree ends of the two corner sections can be securely joined together thereby to form a corner member while also providing, adjacent to the corner section tine receiving slot, a keyway especially shaped and configured so as to enable insertion therein of an adjustment key which, when inserted therewithin, enables controlled opening of a space between the two corner sections; and, extending from each of the 90 degree ends of the corner sections, at least one corner member tine especially shaped and configured to allow mating engagement with the corner tine receiving channel of a perimeter member thereby enabling the 90 degree end of the corner sections to be securely affixed to a perimeter member; joining the four perimeter members of required length with four corner members by inserting the corner member tines extending from the 90 degree ends of each of the four corner members into the corner tine receiving channel of the perimeter members so as to form a stretcher frame of a desired perimeter measurement without having to mortise or perform any further joinery upon said perimeter members to join same. |
