NOTICE

If the handwheel is adjusted so the spindle slide completely moves to the lowest position, and the handwheel is forced further past the stop, the gib can fall out of place and bind the spindle slide on future upward travel. To correct this issue if it occurs, loosen the setscrews, and reposition the gib, and adjust the spindle slide-to-gib clearance as outlined to the right.

Spindle Slide and Gib

The spindle slide-to-gib clearance may need adjusting so there is no play when pressure is applied to the spindle. Gib adjustments are made by loosening or tightening some or all of the four setscrews on the side of the elevation housing shown in Figure 31.

To check the spindle slide-to-gib clearance, do these steps:

1. UNPLUG THE SHAPER!

NOTICE

The spindle lock keeps the spindle in a fixed position during shaping operations. Since cast-iron threads can strip, DO NOT over-tighten the spindle lock.

2.Turn the handwheel until the spindle is in the highest position.

3.Lock the spindle in place by tightening the spindle lock handle on the side of the shaper.

4.Grasp and wiggle the top of the spindle to see if there is side-to-side movement. If there is movement, adjust the gib to remove this play.

To adjust the spindle slide-to-gib clearance, do these steps:

1.UNPLUG THE SHAPER!

2.Loosen the setscrew jam nuts.

3.Slowly turn the four setscrews. Alternate between the top and bottom so the pressure will be uniform.

4.Tighten the hex nuts while holding the setscrews in position.

5.Recheck the spindle slide up and down movement. No play should exist and the spindle should move up-and-down smoothly. It may take several attempts to adjust the spindle slide-to-gib clearance to get the spindle to move up and down smoothly.
