18. Tailstock.
The tailstock, which provides right-end support for the work, moves along
the bed and can stop at any point on it. It holds centers, drills, reamers, taps, and other
tools. To move the tailstock spindle, which has an MT3 taper, turn the tailstock hand
wheel. The scale of offset calibrations on the back of the tailstock is in millimeters.
Note:
To offset the tailstock, loosed the four base locking bolts. To offset to the left,
loosed the left adjusting bolt and tighten the right and do the same on the other side
when you want to offset to the right. See figure. 4.2.
