Changing Spindle Speeds
The lathe features three step motor and Headstock
spindle pulleys. These three drive ratios are used in
conjunction with the electronic variable speed control to
provide maximum power and speed when required.
1, Open both motor pulley and Headstock pulley access
doors.
2, Loosen motor locking arm and raise motor.
3, Move drive belt to selected drive ratio.
4, Lower motor for adequate belt tension and tighten
locking arm.
(Do not apply excessive load onto the belt prior to locking,
as damage may result.)
- High ratio range - (small diameter Headstock pulley
/ large diameter motor pulley) . This ratio is for faster
speeds - eg. Spindle turning and small Faceplate projects.
- Medium ratio range - (center Headstock / Motor
Pulley diameters). This ratio is suitable for most general
woodturning work such as Spindle and Faceplate projects.
- Low ratio range - (large diameter Headstock pulley /
small diameter motor pulley). This range will provide
maximum lower speed power ideally suited for larger Bowl
turning projects.
* Once the desired ratio has been selected, fi rstly ensure
the project is fi xed to the machine in a strong and safe
manner and fully supported by the Tailstock where
possible.
5, Make sure the speed control knob is set on the slowest
"o" position.
6, The machine can now be started with the speed control
knob being slowly increased until a suitable and safe
cutting speed is achieved.
*Note! For operator safety, always return speed control
knob to "O" position when stopping the machine.
Typical Operations
The lathe is set up for a typical spindle turning
operation.(See Fig.15)
