Gauge Blocks
Tools Needed:	Qty
6' Long 2x4	1
Miter Saw (or Circular Saw)	1
Jointer	1
Table Saw	1

The gauge blocks described here will be required to complete most of the service procedures in this section. After you have made them, they can be conveniently stored inside of the sander cabinet for future use.

To make the gauge blocks:

1.Edge joint the concave edge of the 2x4 flat on a jointer, as shown in Figure 27.

2.Place the jointed edge of the 2x4 against the table saw fence and rip cut just enough off the opposite side to square up the two edges of the 2x4, as shown in Figure 28.

3.Cut the 2x4 into two even pieces to make two 36" long wood gauge blocks.

Note: The Steps 1 & 2 can be skipped, but having these wood gauge blocks at an even height is critical to the accuracy of your over- all adjustments.

Tension

New V-belts often stretch and loosen up during the first 16 hours of use. After this period, they should be inspected and re-tensioned if neces- sary.

Proper tension is important for optimum power transmission. However, too much tension may cause premature bearing failure.

The correct V-belt tension is achieved when the V-belts can be deflected 1⁄2"–3⁄4" when pushed in the middle with moderate pressure. See Figure 29 for an example of how to perform a V-belt deflection test with a straightedge and ruler.
