Adjusting Spindle Speeds - Woodstock Shop fox W1856 Owner's Manual

Adjusting.Spindle.Speeds
Your lathe has three speed ranges for maximum turning
options. These ranges are selected by changing belt
positions on the motor and spindle pulleys, which
are accessed through the rear and side covers on the
headstock.
Refer to Figure.19 for belt positions and speed ranges.
High range (A) is best when turning a workpiece where a
clean finish is required and only light cuts are made.
Mid range (B) is a compromise between high and low
ranges.
Low range (C), which has more torque, is best when
turning a workpiece where a lot of material must be
removed and a rough finish does not matter.
Use the speed dial to adjust spindle speed within each
range.
Refer to the spindle speed recommendation chart (see
Figure 20) to choose the appropriate RPM for your
operation, then choose the speed range that will include
the selected RPM.
