Abstract:
A method of manufacturing a climbing nut having an upper face and a lower face, a first pair of opposed side faces and a second pair of opposed side faces, the method comprising the steps of:(a) providing an ingot of a desired size and composition; (b) cutting said ingot to remove material therefrom to define first and second pairs of opposed side faces of a work piece, and so that one face of each of said pairs defines a concave surface and the opposite face of each of said pairs defines a convex surface, and further so that said concave surfaces have lateral side edges and at least one of said concave surfaces further comprises a concave section extending only partially across said face to define opposed leg sections extending along the lateral edges of said face, and wherein said work piece defines a trapezoid; (c) drilling at least one bore through said work piece, said bore defining a bore axis; and (d) cutting said work piece in a direction transverse to said bore axis to define said upper face.
