Anyone doing repetitive lathe operations on small parts will find this new accessory saves a lot of time when holding parts into a WW collet. Instead of loosening and retightening the drawbar each time a part is inserted, with this closer you to make that adjustment just one time. After that, the collet is released and retightened simply by pushing a lever back and forth. Moving the lever to the right releases the part from the collet, a new part is inserted and the lever is moved back to the left to lock the part in the collet. Hardened steel components assure long life.
Long stock up to 3/16" in diameter can be held through the WW collets and spindle. Larger parts up to 5/16" or 8mm can be held in the face of the collet, and collet pot chucks are available for even larger parts up to 1" diameter.
The new collet closer is easy to install on a Sherline lathe with no holes to be drilled. It simply clamps to the leadscrew support by tightening two 10-32 screws in the split base, and a single 4-40 socket head screw secures the upper part to a pre-existing hole in the headstock spindle. A self-tapping 4-40 screw is included to tap this hole, although it may already be threaded if you have used a P/N 3100 threading attachment on the lathe in the past. A collet adapter with a registration pin is included that engages in the keyway of the WW collet to keep it from turning in the adapter. 3/32" and 5/32" hex keys are also included. As usual, installation and operation are covered in the thorough, illustrated instructions that come with it.
