-12- G8690 Variable Speed Wood Lathe
SECTION 5: OPERATIONS
Once assembly is complete and adjustments are
done to your satisfaction, you are ready to test run
the machine.
Press the START button. Make sure that your fin-
ger is poised on the STOP button, just in case
there is a problem. The lathe should run smooth-
ly, with little or no vibration or rubbing noises.
Strange or unnatural noises should be investigat-
ed and corrected before operating the machine
further.
If you cannot easily locate the source of an
unusual noise or vibration, contact our service
department for help.
Test Run
To mount a workpiece between centers:
1. Locate the center point on both ends of the
workpiece by carefully drawing diagonal lines
from corner to corner. The point of intersec-
tion is the center of the work. Find the center
of round wood stock by using a center finder
instrument.
2. When turning stock with a diameter greater
than 2", remove the corner length edges with
a hand plane or similar operation as shown in
Figure 6A.
3. Hold the spindle vertically and support it on a
solid surface. Line up the spur center with the
center of the workpiece. Drive the spur cen-
ter into the stock about
1
4" using a dead blow
hammer. Be careful not to split the work-
piece. See
Figure 6B.
Wood with splits along
the grain may fly off during the operation.
With dense wood, drill a hole at the centers
and score lines with a saw blade for the spur.
Spindle Turning
Wear a face shield dur-
ing the test run and
operation of this wood
working lathe. Failure to
do so could result in
serious injury.
D"
If measurement D" is greater
than 2", cut off the corners of
the wood stock.
Wood Stock

Keep loose clothing
rolled up and out of the
way of machinery and
keep hair pulled back.
Make sure the live center in the tailstock
lines up with the spur center in the head-
stock before turning anything between the
centers. Failure to observe this step could
result in the workpiece being thrown from
the lathe. Serious personal injury could
occur if care is not taken.
