Adjusting Gibs

The function of the gibs is to take out play in the table, and cross slide, and column without causing the slides to bind. The gibs are pre-adjusted at the factory and should not need further adjustment until many hours of machine use. If the movement seems too tight at first, make sure the locks are fully released. Next, make sure the bedways are thoroughly cleaned of rust preventative and lubri- cated with oil.

Each gib has multiple lock nuts and set screws that need to be adjusted. Make your adjustments equally and in small increments.

To adjust the gibs: (see Figure 27)

1.UNPLUG THE MILL/DRILL!

2.Loosen the lock nuts.

3.Move the table and slightly tighten each set screw. When properly adjusted, the gib should offer slight resistance without bind- ing.

4.Tighten the lock nuts.
