Abstract:
1. A hollowing system for a lathe having a tool rest, the hollowing system comprising: a boring member adapted to support a tool such that at least one of the boring member and the tool extend past and engage the tool rest, the boring member having a longitudinal axis; and a stabilization assembly mountable adjacent to the lathe, the stabilization assembly supporting the boring member so that the boring member can reciprocate along its longitudinal axis, the stabilization assembly having a vertical axis and a horizontal axis, the stabilization assembly adapted to prevent downward movement of the tool when the stabilization assembly is mounted adjacent to the lathe and the tool is extended past and supported by the tool rest causing downward forces to be applied to the tool when the tool engages a workpiece, the stabilization assembly comprising: a rotational prevention assembly engaging the articulation assembly and the boring member to selectively permit and prevent rotation of the boring member about the longitudinal axis of the boring member.
