A stainless steel cable (1) typically of 1.5 mm diameter has a ferrule (2) threaded on it. The ferrule is of polypropylene and has a stepped bore, with a small bore portion (3) and a large bore portion (4). The large diameter portion is arranged at the end of the ferrule adjacent an end (5) of the cable. To secure the ferrule to the cable, the cable is unlaid at its end (5). The result is that the strands of the cable splay out, typically beyond the external diameter of the ferrule. Epoxy resin (6), is applied to the cable at the ferrule and the splayed end. When the adhesive is well distributed, the cable is drawn through the ferrule to introduce the splayed end into the larger diameter portion. The splayed strands rest against the large diameter bore at the orifice (7) of this. At the step (8) between the diameters, the adhesive will have been drawn in to occupy any air space that would exist between the cable and the ferrule in the absence of the adhesive. Once the adhesive has set, the ferrule will be secured to the end of the cable. The cable can be trimmed back to the length of the ferrule at (9). |
