Sherline's Compound Slide offers a way to turn taper and cut angles on a lathe without rotating the headstock. Four mounting holes are provided in the base for solid positioning on the crosslide.. The rotating portion has a red anodized finish with laser engraved angles scales to make setting an angle easy. It utilizes a highly efficient locking ring design to lock it in position without having to over-tighten the locking screws. A 1/4" cutting tool can be mounted across the front or on either side of the head.
