Do not press the workpiece too firmly with
the tailstock or the bearings will bind and
overheat. Do not adjust the tailstock too
loosely or the workpiece will spin off the
lathe. Use good judgment and care, other-
wise serious personal injury could result
from the workpiece being ejected at high
speeds.
11. Properly adjust tool rest to workpiece (see
Adjusting Tool Rest on Page 22).
