Workplace
Practice
Series
Dividing
by
Harold
Hall
explains
how
radial
work
on
a
metalworking
lathe,
such
as
the
cutting
of
gear
wheels
or
the
drilling
of
holes
on
a
set
radius,
calls
for
a
method
of
precisely
spacing
the
cuts.
The
principles
underlying
this
aspect
of
engineering
are
explained
in
depth
in
this
book.
Faced
with
the
prospect
of
machining
a
gear
or
gears
for
a
project,
many
model
engineers
will
be
discouraged
and
will
turn
elsewhere
for
their
next
model.
This
need
not
be
so,
for
the
principles
underlying
gear
cutting
and
many
other
aspects
of
engineering
where
an
accurate
division
of
circles
is
required
are
explained
in
depth
in
this
book.
It
covers
the
subject
of
Dividing,
dealing
with
the
many
methods
that
can
be
adopted:
from
simple
applications
without
specialised
equipment
to
the
use
of
a
semi-universal
dividing
head
and
a
rotary
table.
The
mathematical
aspects
of
dividing
are
also
covered
but
at
a
level
that
will
be
understood
easily
by
a
model
engineer.
Dividing
equipment
is
relatively
expensive,
so
two
fully-detailed
designs
are
included
for
dividing
heads:
a
basic
unit
and
the
equivalent
of
a
commercial
semi-universal
head.
Author
Harold
Hall
has
established
his
reputation
as
a
mentor
to
tyro
engineers
through
the
pages
of
Model
Engineers’
Workshop
of
which
he
was
the
editor
for
a
number
of
years
and
through
his
other
two
books
in
this
series,
Lathework
–
A
Complete
Course
and
Milling
–
A
Complete
Course.
The
Workshop
Practice
Series
is
the
world¹s
leading
range
of
books
for
model
engineers
and
mechanical
crafts:
some
of
the
books
have
been
in
print
for
50
years;
most
of
them
still
reprint
every
18
months.
