The Sherline collet fixture was designed to be mounted on the surface of the rotary table or the mill table. A knurled ring allows WW collets to be pulled into the taper and closed without the use of a drawbolt from the back. This is particularly useful for clockmakers for gearcutting on a gear blank that has a pinion shaft attached that can be held in a collet. A bushing is provided that fits into the center hole of the rotary table and helps center the fixture on center. T-nuts and attaching screws are also provided for clamping the fixture in place in the rotary table or mill table T-slots.
