draw bar on drill chuck

how is it used on the lathe---tks,joe

[Fred Ray]

Generally the draw bar is simply a piece of all-thread rod that screws into the end of the morse taper on the chuck, extends through the headstock, exiting at the handwheel. You put washers and nuts or a hand nut on that end and tighten down to hold the chuck in the headstock. This is to keep the morse taper fit from slipping and flying out of the headstock at very inoppotune times.
