Floor Mounting
Once you have confirmed that your Model G7946
is running properly, we strongly recommend
mounting it to the floor to ensure optimum
stability.
Lag shield anchors with lag bolts and anchor
studs (
Figure 16) are two popular methods for
anchoring an object to a concrete floor. We sug-
gest you research the many options and methods
for mounting your machine and choose the best
that fits your specific application.

Mobile Base Mounting
Because the Model G7946 drill press is top-heavy
by nature, we recommend mounting it to the floor,
rather than a mobile base.
If you must use a mobile base, ALWAYS mount
your drill press to a base plate inside of the mobile
base, as shown in
Figure 18.
A good quality base plate increases the standard
footprint of the drill press to make it much more
stable. The base plate must be at least 1
1 ⁄
2
" thick
and made of plywood (do not use OSB, MDF,
or particle board) to hold the weight of the drill
press. A common way for making the baseplate is
described in this sub-section.

To make and use the base plate:
1. Glue the two pieces of plywood together,
and align the edges and corners so the two
boards make one thick piece.
2. Use the wood screws to fasten the boards
together from both sides.
3. Allow 24 hours for the glue to dry before
placing the drill press on it.
4. Place the base plate on the mobile base.
5. Drill holes through the base plate and the
metal plates at the corners of the mobile
base.
6. Secure the base plate to the mobile base
with hex bolts, hex nuts, flat washers and
lock washers, as shown in
Figure 17.
Drill presses are top-heavy and must be
securely attached to a large-footprint base
plate when used with a mobile base. Failure
to use a base plate greatly increases pos-
sibility of tipping and personal injury.
