The Lathe-Type Undercutter can be quickly attached in place of the tool post on any lathe. It can be mounted directly on the cross slide, or on the slide carriage which is then mounted on the cross slide.
The slide Carriage is lever operated and is much faster than using lathe carriage. Travel is 11" on the Model 110, 15-1/2" on the Model 110L15 and 21" on the Model 110L21, with adjustable stops at both ends. A Skewed bar adjustment is provided at the right end.
Both Horizontal and vertical commutators can be under cut. As undercutting is done from the side of commutator the saw or V-cutter is set level with the Lathe centers.
Undercutter is powered by a 1/3 h.p. motor and uses High Speed Steel or Tungsten-Carbide Saws or V-Cutters.
A spring between hardened washers under the pulley allows the spindle to move ("float") up or down and follow and existing slot that is being re-cut. If a fixed spindle is desired, the spring can be removed and the pulley turned over.
