Adjusting the metal strips, or Gibs (94/107) on the underside of the Compound Rest A (108) and the Cross Slide (100) helps to snug up those units so they slide smoothly along the lathe. The goal is to tighten them enough so that the Compound Rest and Cross Slide do not have any unnecessary movement, but not so tight that they bind. It should not be difficult to turn the hand Cranks (86A/86B).

The Gibs become loose with use, so the Compound Rest A and Cross Slide should be checked periodically for any play. Readjust the Gibs as needed.

To make the adjustment:

1.Unplug the Lathe.

2.Working one set of three gib Screws and Nuts at a time, loosen the three Nuts (98) with a wrench (sold separately).

3.Holding the center Nut with the wrench, loosen or tighten the Center Screw (99 or 106) with a flat head screw driver

(sold separately) and check the sliding movement. It should be even and smooth while removing any play. Adjust as needed, then, holding the Screw with the screw driver, tighten the Nut with the wrench.

4.Repeat step 3 for the two side Screw/Nut sets.

Tailstock Alignment

The Tailstock (138) needs to be adjusted for offset, then re-aligned before first use and any time the tool in the Tailstock is changed.

To align the Tailstock:

1.Center drill both ends of a 6” long piece of round cold rolled stock. Set aside.

2.Turn a 60° point on a piece of scrap metal to make a dead center.
