Delta 31-140 Angled and END Sanding Using the Miter Gauge, Bevel Sanding Using the Table Tilt

OPERATION

ANGLED AND END SANDING USING THE MITER GAUGE

The majority of work performed on the DELTA® 12” Disc Sander is usually accomplished using the table as a support. For accurate sanding of angled and end-grain surfaces, as shown in Figure 7, your disc sander comes with an adjustable miter gauge (A) and 3/8" x 3/4" t-slot

(B)machined into the table. To use the provided miter gauge for angled or end-grain sanding , do the following:

m a k e c e r t a i n m a c h i n e i s disconnected from power source

before making adjustments.

•Slide the miter gauge into the t-slot.

•Loosen the miter adjustment handle (C) by rotating it to the left and adjust the miter gauge to the desired sanding angle. Tighten the miter adjustment handle.

•Ensure the workpiece is positioned along the miter gauge before turning the machine on and starting to work.

The table can be tilted up to 45 degrees up or down. A scale (A), Figure 8, and pointer (B) are provided to indicate the degree of tilt. Ball-indent positive stops on the tilt adjustment indicator are located at 0°, 35°, and 45°.

To tilt the table up or down, loosen table locking wing nut (C) and rotate the knob (D). As the knob is rotated, the table will pivot either up or down. Turning the knob clockwise will make the table tilt downward. Turning the knob counterclockwise will tilt the table upward. Pivot the table until desired angle is established. Then tighten table locking wing nut.

Regardless of which position the table is tilted, the table edge (E), shown in Figure 10, must be no more than 1/16"

from the sanding disc to avoid trapping the work or fingers between the table and sanding disc. To adjust the position of the table relative to the sanding disc, see “adjusting miter gauge slot alignment “ on page 11.

We suggest that all bevel sanding applications be performed with the table tilted down as shown in Figure 9; however, if

there is a need to tilt the table up, the workpiece must be securely fastened or clamped to a fixture or jig to prevent the workpiece from being torn from hands and becoming trapped between the table and sanding disc. See Figure 10.
