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:
Unplug the Lathe.

Working one set of three gib Screws and

Nuts at a time, loosen the three Nuts

(98) with a wrench (sold separately).
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.
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:
Center drill both ends of a 6” long piece

of round cold rolled stock. Set aside.
Turn a 60° point on a piece of scrap

metal to make a dead center.
