ABSTRACT:
A tailstock for rotatably supporting a workpiece on a machine bed. The tailstock includes a vertical column fixed at the machine bed which has first and second regions. The second region of the column is coaxial with the first region and pivotally mounted to the first region. An offset arm extends laterally from the vertical column and carries a center for engaging the workpiece. The offset arm has an opening for accommodating the regions of the vertical column and is longitudinally displaceable thereon. The offset arm is pivotable when disposed at the second region and non-pivotable when disposed at the first region to dispose same in repeatable precision relation to the machine bed.
