7.3 Removing items from bed
To remove headstock, tailstock or toolrest base
from bed, unscrew and remove either of the studs
(see O, Figure 5-6). Unlock the item and slide it off
bed. After remounting these items on the lathe,
reinstall studs.
For most turning operations, except outboard
turning, the headstock is positioned at the left end
of bed, and the tailstock moved to accommodate
the workpiece.
7.4 Cam tightness
The clamping mechanisms of headstock, tailstock
and tool rest base are pre-set by the manufacturer,
and should not require adjustment.
If one of them does not tighten properly against the
bed when the locking handle is tightened, adjust it
as follows. (Figure 7-4 uses tailstock as example.)
