to a mounting board 18" x 24" or larger. The diagram
in Fig. 16 shows the size and center-to-center
distance of the holes that you will need to drill in the
mounting board.
N O T E : For proper stability, countersink the holes
underneath the mounting board so that the screw heads
are flush with bottom surface.
4. Securely clamp the mounting board to a stand or
workbench using 2 or more “‘C” clamps, as shown in
Fig. 17.
Secure the machine base to the supporting
surface. If there is any tendency for the stand or workbench
to move during operation, the stand or workbench must be
fastened to the floor.
