leveling & mounting
for accurate turning results and to prevent
warping the cast iron bed and ways, the lathe
bedways must be leveled from side-to-side
and from front-to-back on both ends.
re-check the bedways 24 hours after
installation, two weeks after that, and then
annually to make sure they remain level.
leveling machinery helps precision components,
such as bedways, remain straight and flat during
the lifespan of the machine. Components on a
machine that is not level may slowly twist due to
the dynamic loads placed on the machine during
For best results, use a precision level that is at
least 12" long and sensitive enough to show a
distinct movement when a 0.003" shim (approxi-
mately the thickness of one sheet of standard
newspaper) is placed under one end of the level.

the chip pan and the base of the lathe have
holes that allow the machine to be mounted to
a workbench. you Must mount your machine
to a workbench to prevent it from unexpectedly
moving during operation, which could lead to
personal injury or property damage.
follow these guidelines when mounting your
lathe to ensure safe and accurate cutting
Make sure that the workbench can adequate-
ly support the weight of the machine and
materials and that it will not move or vibrate
use a silicon sealant between the lathe and
the chip pan to prevent coolant or other fluids
from leaking through onto the bench or floor.
to mount the lathe and chip pan to the workbench,
drill holes all the way through the workbench, and
use hex bolts, washers, and hex nuts to secure
the lathe to the workbench, as illustrated in
figure 16. example of a through mount setup.
