  • Page 48: Adjusting Gibs

    Adjusting Gibs gibs control the accuracy of table and ram move- ments along the ways. tight gibs make the move- ments more accurate, but harder to move. Loose gibs make the movements sloppy, but easier to move. the goal of gib adjustment is to remove unnecessary sloppiness without causing the ways to bind.
