Attaching Sandpaper

The disc sander accepts 12" diameter cloth or paper-backed PSA sanding discs, which are available through Grizzly (see Page 28).

The sanding disc sticks to the surface of the cast iron disc, using the pressure sensitive adhesive backing (PSA) on the reverse side of the sandpa- per disc. The sandpaper can be replaced without removing either the table or the dust port.

To attach sandpaper:

1.Peel back the protective layer on one-halfof the sandpaper disc and fold it against the remaining half.

2.Slip the half with the protective layer between the disc and the table edge.

3.Position the exposed adhesive on the upper half of the disc that extends above the table. Once it is positioned evenly across the disc, press the adhesive onto the surface.

4.Now rotate the disc so the lower half is now above the table.

5.Bend the paper back and remove the remain- ing half of the protective layer (Figure 30), then press the adhesive portion against the disc.

Disc Sanding

To perform sanding operations:

1.Set the angle of the table relative to the sand- ing disc. The angle can be set with the angle gauge on the disc sander or with a protractor for greater accuracy.

2.When a 90˚ horizontal angle is required, place one surface of the workpiece firmly against the face of the miter gauge (set at 0˚), with the other surface against the face of the disc (Figure 31).

Note: For sanding curves or irregular shapes, remove the miter gauge from the disc table. Always keep the workpiece on the side of the wheel that is rotating down toward the table. This will keep the workpiece from flying out of your hands from the rotational forces.
