ABSTRACT:
A wood turning lathe is provided with a centrally located head and tail stock mounting apparatus which in combination with head and tail stocks on the opposite ends of the lathe define two turning stations. The mounting apparatus includes a supporting block unit having head and tail stock work centers rotatable about a common axis with the head stock center being held against axial movement. The tail stock center is hydraulically operated to be selectively reciprocable. This reciprocable movement is provided by means of a hydraulic power cylinder in the supporting block unit having a sealed chamber which receives a piston mounted on a rotatable shaft which carries the tail stock center. The piston divides the chamber into two variable volume compartments, two ports in the block unit being provided for admitting an exhausting pressure fluid to and from such compartments, respectively.
