Using the Collet Closer Stops
The stop block threads into the back of the WW collet knob. Included are four different length rods for various ranges of adjustment. The rods are held in place by a set screw. With the proper rod in place, the material is inserted in the collet until it hits the stop, providing a consistent position for a series of identical parts. A scribed mark 1.5" from the end of each rod shows when the rod is extended past a safe operating distance from the end of the spindle. If the scribe line can be seen, the next shorter rod should be substituted.
