Abstract
A lathe has a plurality of turret positions with at least one having a toolholder, a pair of blades projecting from one end of the toolholder with the toolholder structured to assume a first position with a first blade machining said workpiece which is rotating in a first direction and a second position with a second blade structured to assume a second position with the workpiece rotating in the other direction. The toolholder remains fixed during machining. Related methods and toolholders are disclosed.

A method of machining a workpiece comprising
- providing a lathe having a plurality of turret positions with at least one said turret position having a toolholder with a pair of relatively spaced blades projecting from an end of said toolholder,
- positioning said toolholder in a first position with a first said blade in contact with said workpiece while rotating said workpiece in a first direction and, subsequently, moving said toolholder to second position with a second said blade in contact with said workpiece rotating in the opposite said direction, and
- effecting said toolholder movement between said first and second positions by translational movement.
A method of machining a workpiece comprising providing a lathe having a plurality of turret positions with at least one said turret position having a toolholder with a pair of relatively spaced blades projecting from an end of said toolholder,
- positioning said toolholder in a first position with a first said blade in contact with said workpiece while rotating said workpiece in a first direction and, subsequently, moving said toolholder to second position with a second said blade in contact with said workpiece rotating in the opposite said direction,
- creating said toolholder by joining a first section to a second section with each section being secured to one of said blades.
