ABSTRACT:
A jaw assembly for use with a lathe chuck which is rotatable about an axis and provided with at least two first cooperative mating portions circumferentially spaced apart about the axis. The jaw assembly includes at least two cylindrical bodies. Each body has a longitudinal axis, a cylindrical outer surface and first and second spaced-apart generally parallel outer planar surfaces disposed in planes generally perpendicular to the longitudinal axis and to the cylindrical outer surface. Each body is adapted to have at least three circumferentially spaced-apart workpiece-receiving cutouts therein extending through at least the outer cylindrical surface and the first planar surface. Each body carries second cooperative mating portions for mating with the first cooperative mating portions of the chuck to secure the body to the chuck so that the body rotates in an immovable manner with respect to the chuck. The bodies are mountable with respect to the chuck to rotate therewith in at least three different positions.
