Leveling & Mounting
You must level your machine and either use the
included foot pads and leveling hardware or bolt
your lathe to the floor. Because mounting your
lathe to the floor with permanent hardware is an
optional step and floor materials may vary, floor
mounting hardware is not included.
Leveling
Leveling machinery helps precision components,
such as bedways, remain straight and flat during
the lifespan of the machine. Components on an
un leveled machine may slowly twist due to the
dynamic loads placed on the machine during
operation.
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
(approximately the thickness of one sheet of
standard newspaper) is placed under one end of
the level.
See the figure below for an example of a high
precision level.
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.
Re-check the bedways 24 hours after
installation, two weeks after that, and then
annually to make sure they remain level.
Figure 11. Example of a precision level.
To level the machine, use a precision level to
make sure the bedways are level from side-to-
side and from front-to-back. If using the included
leveling pads (Figure 12), place them under
the six leveling bolt locations, then use a 24mm
wrench to adjust the bolts and level the lathe.
If using mounting hardware that does not allow
for adjustment, level the lathe by placing metal
shims between the lathe base and the floor before
bolting down.

Stud
Lag screws and anchors, or anchor studs
(below), are two popular methods for securing
machinery to a concrete floor. We suggest you
research the many options and methods for
securing your machine and choose the best one
for your specific application.

machinery to concrete floors.
Most electrical codes require that machines
connected to the power source by fixed
conduit MUST be secured to the floor.
