The device of the invention comprises a stationary member, a moveable member adjacent to said stationary member, indicator means attached to the moveable member for contacting a work piece, said indicator means being moveable through a substantially 360 degree arc in a plane substantially perpendicular to the center axis of the machine drive member, fixing means for alternatively permitting or preventing movement of the moveable member relative to the stationary member, and locating means on said moveable member and on said stationary member for indicating the relative position of the moveable member to the stationary member in each quadrant of that arc. The method of the invention comprises four steps in which the work piece is centered with respect to a machine tool drive member along two perpendicular axes.
