Lag screws are installed into pre-drilled holes in
the table top. Sometimes glue is applied to serve
as thread lock to keep fasteners in place from
vibration. Rubber feet are omitted for this rigid

Figure 6. Through mount using nuts and bolts
for maximum rigidity when grinding.
This is a common mounting selection for large
grinders where maximum rigidity is required to
prevent creating an out-of-round grinding wheel
from workpiece hop. Generally the rubber feet are
omitted in rigid mounting.
Through Mounting
The grinder must be mounted to a solid surface to
prevent unexpected movement during operation
that could result in injury or property damage.
Below are three of the most common options for
mounting grinders. Keep in mind that no single
grinder height is acceptable for all users. Poor
posture, such as hunching over or having to rest
a foot on the edge of a crate or workbench shelf
for better comfort, can lead to lower back and
neck strain—especially if grinding is to be done
for extended periods of time.

Figure 5. "Through Mount" with rubber feet
installed.
Mounting with rubber feet allows for quieter
operation and less workbench vibration. The feet
are typically compressed about 25%. Locking hex
nuts must be used to prevent the mounting bolts
from loosening.
