MOUNTING THE DRILL PRESS ON A PLYWOOD BASE
If you do not fasten your machine permanently, then you must fasten the drill press to a plywood mounting board to prevent
it from tipping over. Use a good grade of 3/4" or thicker plywood. DO NOT make the mounting board from particle board.
1. Start with a 21" x 28" or larger piece of plywood. Drill two 3/8" diameter holes (B) Fig. 25 that match the mounting holes
(A) Fig. 24 of the drill press base.
2.
Fasten the drill press base to the mounting board using the carriage bolts, flat washers, lockwashers, and hex nuts
(C) Fig. 25, furnished with your drill press. The holes for the carriage bolt heads and flat washers under the board
must be countersunk so that the bolt heads are flush or below the bottom surface of the board. Make sure to use
a flat washer, lock washer and hex nut above the drill press base.
3. The supporting board must extend a minimum of 3" beyond each edge of the drill press base (Fig. 26).
4. Secure the plywood base to the floor or supporting surface if the drill press has any tendency to vibrate, slide, or walk
during normal operation.

through the two holes (A) Fig. 24 located in the machine base.
