PRE FACE
This Manual of Lathe Operation has been
prepared to pr ovide authentic, up to date, and
complete operating information for owners of
all types of metal cutting lathes.
Fundam enta l and concrete theory , as well
as operating pr oc edure, is included in order
to make this book suitabl e for students, ap-
prentices and vo cational schools. Much of the
data will prove invaluable to the machinist
and the more e xper ie nced lathe op e rator .
It is our hope tha t this Manual will further
the advancement of th e lath e us er in all walks
of industry. If we ha ve helped him , even in a
small way, the research and labor involved in
the preparation of this book will have been
well worth while.

We wish to extend our sinc ere appreciation
to the many manufacturers , en gi neers and ma-
chinists who have assisted in the preparation
of the technical material in this material. If
the reader desires furth er info r mation on any
of the metals or pla s ti cs me ntioned , we will

The history of modern machinery started in the last years of
the eighteenth century when Henry Maudslay, an Englishman,
built the first practical screw-cutting lathe. When compared with
a modern precision lathe, this machine was slow and clumsy, but
from the basic principles of Maudslay's lathe have come nearly
all modern machine tools. The skill of early New England
machinists in developing his theories soon put the United States
in the front rank among industrial nations of the world.

Today, more than 150 years after Maudslay, the screw-cutting
lathe is still the heart of industrial manufacturing. It seems odd
to consider the lathe so vitally important when large batteries of
automatic machines are used in every modern factory. But pay
a visit to the factory tool room where the machining is done which
makes possible the construction of these huge automatic machines.
There you will find a lathe, easily the most important tool, busy at

the hands of an expert machinist turning the plans of designers
and engineers into new tools and machines for modern industry.
The lathe is the "King of All Tools"-more jobs of a mechan-
ical nature can be done on a lathe than with any other dozen tools.
In the machine s hop , experimental shop, or home workshop, the
metal lathe is ca lled upon for many operations. Turning, milling,
grinding, drilling and boring must be performed on iron and steel;
wood, plastics, alloys and soft metals must be shaped into form;
threads of all sizes a nd s hapes have to be cut; and machine parts
need repairing or replacing. Manufacturers, tool and die makers,
experimenters, automoti ve men, model builde rs , inventors-thou-
sands of businesses, hobbies, and professions depend on a preci-
sion screw cutting lathe with its many attachments.
