ABSTRACT:
An adapting device is provided including a dead center with a cylindrical body and a live center with a tubular body, both of the centers including tapered center defining noses. A pair of yokes are adapted to secure the centers to V-blocks of a V-block instrument with their axes coincident with one another. A live center useful for adapting a V-block gauging instrument into a bench-center instrument is provided having a tubular body with a centering member slidably received therein. The centering member includes a neck portion extending through a reduced diameter opening in the tubular body. A spring biases the member so as to engage a piece to orient it for taking measurements, and a cam member pivots about the neck portion to retract the member when a piece is being mounted. A locking member is provided having a metal screw with a hex opening therein and a thumb grip secured over the screw head. An opening is provided in the thumb grip to allow access to the hex opening.
