The end gauge which is shown removed from the chuck in [Fig. 695], is composed of a hollow shank a fitting the hole in the turret, and a gauge rod b fitting the bore of the shank. The shank a may be set farther in or out of the turret, and the rod b may be set farther in or out of the shank, the two combined being so set that when the turret is clear back against its stop the end of the rod b will gauge the proper distance that the bar iron requires to project outwards from the chuck of the machine. The centre shown in [Fig. 696] corresponds to an ordinary lathe centre, and is only used when chasing long work in steel.
