Optional bases for the Original and Classic manual Case Trimmers.

  • Extruded aluminum, I-beam-style base resists lathe torques.
  • An adjustment of ½″ (in ¼″ increments) is built into the Original Case Trimmer, allowing its capacity to be widened before it becomes necessary to use a Long Base (6½″). To adjust, use the outer set of holes on the Collet Housing and Bearing to mount them to the Base.
