The sizes given for a 70-ton rope are shown in Fig. 9and are probably somewhat greater than necessary. Into thishollow cone, about 9 inches of the ends of the wires of the rope arecarefully and evenly spread out, and then fixed in their positionby running in good white metal. The end of the rope is thenpractically a solid cone (an actual end was produced for inspec-tion) which cannot be drawn out (Fig. 3).

A steel-point (Fig. 4) is driven into the centre of the rope, to effect the primary spreading of the wires. This point is thenwithdrawn, and another steel-point (Fig. 5) inserted, which spreadsthe wires still further. This is in turn removed, and its place istaken by a larger steel-point (Fig. 6), first alone and again withthe funnel (Fig. 7) around it, forming a sort of trocar. Thus,the funnel is driven in as far as possible and its threader removed,leaving the wires spread out to their fullest extent by the formeralone, and then they are carefully wiped as clean as possible. The white metal is then run down through the funnel, so thatthe innermost
