Chuck Stepping Device

In this device, shown in Fig. 71, A rests in chuck slightly less than diameter of work. B tightens in rear end of draw-in-spindle. Turning c regulates depth of step.

By the use of this tool any wire chuck will accurately serve as a step chuck. It is a device of great service to the watchmaker when used and understood. It enables him to make a step in any wire chuck of any depth he may wish, and will push out the work if desired. It is very useful many times for a stop for marking or cutting off when you want a number of pieces of the same length or kind. Many object to the stepped chuck for general use, objections which this device obviates.
