camlock stud
adjustment
When fitting a chuck or faceplate with camlock
studs, or when mounting a new chuck or face-
plate, it may be necessary to adjust the camlock
studs.
in order to properly install or adjust one or more
camlock studs, you must remove a stud locking
cap screw, then thread the camlock stud in or out
until the line on the side of the stud is flush with
the top of the chuck casting (
figure 39). this is
an initial adjustment.
When you place the chuck onto the lathe spindle,
you may find that one or more camlocks do not
fully point between the "
v" marks on the chuck.

camlocks and never release.
