Adjust and Secure the Tool Rest
The guidelines for setting up the tool rest are
similar to spindle turning. Tool rest should
support the tool without too much overhanging
and allow the tool to be presented at the right
angle.
When using a straight tool rest to turn a round
object, the woodturner must extend the tool
reasonably further to perform a cut. When
setting up the tool rest, identify a section of the
blank that is safe to work on with a reasonable
amount of tool extended. When that section is
finished, stop the lathe and readjust the tool rest.
This article written by Stuart Batty has
suggestions for the maximum amount of
overhang allowable for various types of
woodturning tools:

For safety, do not over extend the tool to
perform a cut. It increases the risk of having a
catch and having the tool pulled away from the
hand.
Set for Spindle Direction and Speed
Like spindle turning, ensure the spindle direction
is set to “FOR” and start from the lowest speed.
Vibration is more prominent when roughing
heavy blanks. Keep the speed low when
roughing a blank with an irregular shape until the
blank is more balanced.
TIP: Putting the drive belt to the right side of the
pulley allows the lathe to run at low speed with
more torque. High torque is needed to turn a
large blank without stalling the lathe.
WARNING
Never go beyond the speed that is suitable
for turning a workpiece. Overspeed can
cause the workpiece to explode and
dislodge from the lathe, resulting in severe
injury or death.
Excessive vibration is a sign that the turning
speed is too high.
