Claim:
1. A cable guide for supporting a slack portion of a drill line of a drilling rig at an overhead position elevated above a draw-works of the drilling rig during a feeding of a new section of the drill line from a supply reel during a slip and cut operation in which a used section of the drill line is removed from the draw works, the cable guide comprising a base member defining a pathway along which the slack portion of the drill line is to be routed, and at least one replaceable wear member configured for removable engagement to the base member in a position lining the pathway defined by the base member such that the drill line moves over a wear surface of the wear member in movement along the pathway, wherein the replaceable wear member features a first material at the wear surface thereof, the base member features a second material of greater hardness than said first material at a surface of the base member that underlies the wear surface of the wear member, and the first material of the wear member has a greater frictional coefficient with the drill line than the second material of the base member, whereby routing of the drill line over said wear surface of the wear member imparts greater frictional resistance to the drill line than if routed directly over the underlying surface of the base member, and the harder second material at the underlying surface of the base member remains intact should the wear member become fully worn through.
