Stock Inspection &
Requirements
some workpieces are not safe to turn or may
require modification before they are safe to
turn.
Before turning a workpiece, inspect all
workpieces for the following:
•
Workpiece Type:
this machine is intended for cutting natural
and man-made wood products, and some
plastics. never attempt to cut any metal,
stone, or rubber workpiece; cutting these
materials can lead to machine damage or
severe injury.
•
Foreign Objects:
nails, staples, dirt, rocks and other foreign
objects are often embedded in wood. While
cutting, these objects can become dislodged
and hit the operator, cause tool grab, or break
the turning tool, which might then fly apart.
always visually inspect your workpiece for
these items. if they can't be removed, do
not turn the workpiece.
•
Large/Loose Knots:
Loose knots can become dislodged during
the turning operation. Large knots can cause
a workpiece to completely break in half dur-
ing turning and cause machine damage and
injury. Choose workpieces that do not have
large/loose knots.
•
Wet or "Green" Stock:
Cutting wood with a moisture content over
20% causes unnecessary wear on tooling
blades, increases the risk of tool grab, and
yields poor results.
•
Excessive Warping:
Workpieces with excessive bowing or twist-
ing are unstable and unbalanced. never turn
these workpieces at high speed, or instability
will be magnified and the workpiece can be
ejected from the lathe causing injury. only
turn concentric workpieces!
Operation Overview
this overview gives you the basic process that
happens during an operation with this machine.
Familiarize yourself with this process to better
understand the remaining parts of the
Operation
section.
To complete a typical operation, the operator
does the following:
1. examines the workpiece to make sure it is
suitable for turning. no extreme bows, knots,
or cracks should exist.
2. prepares and trims up the workpiece in a
jointer or table saw to make it roughly con-
centric.
3. installs the workpiece between centers.
4. adjusts the tool rest to within
1
⁄
8
" of the
workpiece centerline, and sets the minimum
clearance between the workpiece and the lip
of the tool rest to
1
⁄
4
" gap.
5. positions and locks any dust collection hoods
near the workpiece to collect wood chips, and
secures in place.
6. Verifies the pulley ratio is set for the type of
wood and size of workpiece installed.
7. Verifies the spindle speed dial is turned all
the way counterclockwise so the spindle
does not start in high speed.
8. Verifies the spindle direction switch is select-
ing the correct direction.
9. Verifies the spindle lock is disengaged,
and the spindle and workpiece rotate freely
throughout the full range of motion.
10. ties back loose hair and clothing and puts
on face shield and respirator. takes all other
required safety precautions.
11. starts the lathe and dust collector, adjusts the
lathe speed, and carefully begins the turning
operation, keeping the chisel against the tool
rest the entire time it is cutting.
