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 23.
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.
