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 difcult 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.

wrench.

sets.
