Bed: The long, rail-like metal base to which
the tailstock, tool base, and headstock are
attached.
Chuck: A mechanical device that attaches to the
spindle and holds the workpiece using clamp-
ing force from attached jaws.
Faceplate: The metal disc that threads onto the
headstock spindle and is used as an alternate
means of holding a workpiece, such as a bowl,
that can't be mounted between centers.
Faceplate Turning: Turning situation in which
the grain of the turning stock is at right angles
to the lathe bed axis, or for workpieces that
can't be held between centers, such as bowls.
Backing Block: A sacrificial piece of wood glued
to the base of the workpiece and screwed to
the faceplate. Often used to prevent mount-
ing marks from appearing on the completed
workpiece.
Headstock: The cast metal box to which the
motor is attached and contains the spindle,
bearings, belts, and electrical components for
operating the lathe.
Index Head: The mechanism that allows the

Glossary Of Terms

Outboard Turning: Turning of workpiece with
the headstock situated at the far end of the
lathe so the work done is not over the bed of
the lathe.
Roughing Out: Taking stock from square billet to
round blank.
Spindle: This term has two meanings. First, it
refers to the threaded shaft in the headstock
to which the faceplate is attached. Second, it
refers to any work that is spindle-turned.
Spindle-Turning: Work performed where the
grain and length of the workpiece are paral-
lel to the axis of the bed, or the workpiece is
held between the spindle center and tailstock
center.
Swing: The capacity of the lathe, measured
by doubling the distance from the bed to the
spindle center.
Tailstock: The metal component at the opposite
end of the bed from the headstock containing a
quill and live or dead centers. It maintains pres-
sure on the spindle-turned workpiece.
Tool Rest Base (a.k.a. Banjo): The movable

the tool rest is fixed.
Tool Rest: The adjustable metal arm upon which
the tool rests during a turning operation.
