摘要： A system is provided for matching a new hole on an overlying member (24) with an existing hole in an underlying member (20). With a magnet placed in the existing hole, an indicator device (30) having an internal cavity, an outer boundry and a ferrous ball freely movable within the internal cavity is slid across the surface of the overlying member and in engagement therewith. When the ferrous ball overlies the magnet, a position on the overlying member aligned with the existing hole in the underlying member is thereby located. Thereafter, the indicator device (30) is removed from the overlying member and replaced by a drill guide (56). The drill guide (56) is used to locate a drill to cut a hole through the overlying member coincident with the existing hole in the underlying member.
