Moving the gib toward the front of the slide increases pressure and moving it toward the rear of the slide decreases the pressure.

Loosen one gib screw a small amount, tighten the other gib screw the same amount, then test the movement of the slide. Continue this process until you are satisfied with the results.

Saddle Gib

The saddle gib is located on the bottom of the back edge of the slide, as shown in Figure 88. Instead of being a wedge-shaped bar like the cross and compound slide gibs, it is a flat bar. Tension is applied by the four adjustment set screws shown in Figure 88.

To adjust the saddle gib:

1.DISCONNECT LATHE FROM POWER!

2.Loosen the hex nuts securing the four adjust- ment set screws, then back off each set screw one full turn to release the pressure on the gib.

3.Manually move the saddle back-and-forth along the bedway to fully release the gib.

4.Tighten each set screw 14 turn, then manually move the saddle back-and-forth to test the results.

5.Repeat Step 4 until you are satisfied with the results, then re-tighten the hex nuts without moving the set screws.

Tailstock Lock

Adjustment

The tailstock clamping plate applies pressure to the bedway when the tailstock lock lever is tight- ened to hold the tailstock in place. The amount of pressure the clamp applies was adjusted at the factory. However, you can re-adjust it if neces- sary.

To adjust the tailstock lock:

 

1.DISCONNECT LATHE FROM POWER!

2.Move the tailstock to a location on the bedway so that you can access the clamping plate hex nut from underneath the tailstock (see Figure 89).

3.Tighten the hex nut a small amount, then tighten the lock lever to test the results.

4.Repeat Step 3 until you are satisfied with the clamping pressure applied with the tailstock lock lever.
