rings
which
are
delivered with
the
machine.
In
that
way,
the
opening
is as
small
as
possible,
and
the
piece
can no
longer
flip
over
and hit the
knives.
Using
a
power feeder
can
prevent
most
serious accidents involving
the
hands. Such feeders
can
easily
be
adjusted
and
adapted
to the
size
of the
pieces.
When
no
power
feeder
is
used,
the
woodpushers
must
be
used,
the
horizontal
and
vertical
springs making
a
tunnel
in
which
the
piece
can be
slid. This pusher, together with other safety
equipment,
reduces
the gap
between
the
cutting tool
and the
guide fences.

Working with
the
spindle
fence
when
the
total length
of the
piece
has to be
machined
In
most
cases
a
straight spindle guard
fence
is
used.
The
pieces
can
therefore guided
in the
angle made
by the
table
and the
fence.
The
vertical
and
horizontal pushers
can be
placed
in
such
a way
that
they make
a
tunnel
in
which
the
first
piece
can be
pushed.
The
second piece
is
then used
to
push
the
first
one,
the
last piece
is
pushed forward with
a
woodpusher.
Special
blocks
must
be
used relative
to the
dimensions
of the
piece. When working panels
of
small thickness, only
the top of the
spring
may be
used,
on
condition
that
the
thickness
matches.
On
a
spindle-moulder,
the
distance between
the 2
extremities
of the
spindle guard fence
must
be
large enough
to
leave enough space
for the
cutter
block. Thus
the
knives,
the
cutter block
and the
spindle shaft
may be
exposed
and the
extremity
of the
piece
may
come
in
contact
with
the
nose
of the
exit spindle guard fence.
These risks
can be
avoided
by
using
a
false
fence between
the 2
spindle guard fences
thus
limi-
ting
the
opening between
them.

Working with
the
spindle fence when only
a
part
of the
piece
is
machined
When working with
the
spindle fence,
and
this between
2
stops
fixed
onto
the
machine table
or
fences,
only
a
part
of the
workpiece
is
machined.
By
doing
so, the
cutting tool
starts
to
machine
the
wood
in the
full
section
of the
wood,
and
does
not
start
at the
front, where
the
cutting
action
is
more
gradual,
and
less
severe.
The
cutting action
is
stopped
before
the
workpiece
end is
reached. This action
is
very dange-
rous
and
needs special care
and
attention.
A
stop,
solidly
fixed
at the
front
and
back, must
be
used (see
the
example further
in
this manual).
!!! A
piece
may
only
be
guided
by
hand when
it is
sufficiently
large,
in all
other cases
a
gauge
or
a
support with protection
must
be
used
in
order
to
avoid serious accidents.
By
means
of the
gauge,
the
piece
can
quickly
and
precisely
be put
into place
and
firmly
held there.
A
quick clamping system, working with
tumblers
or
with
cams,
is the
most
practical
system
to
hold
the
piece.
When
the
front
and
backstops
are
fixed
to the
spindle guard fence
or to the
table,
a
better con-
trol
of the
gauge
is
possible.
10.
Working with
the
ring quard
When working with
the
ring guard,
a
support
must
be
used, except when
a
certain process does
not
allow
this,
i.e. when
the
piece
is too
large
to
make
the use of the
support practical,
or
when
the
piece
is so
small
or so
difficult
to
machine
that
it
cannot
be
held
in the
support without
danger.
The final
shape
is
obtained
by
holding
the
gauge against
a
guidance bearing which
is
fixed
to
the
spindle
while
the
piece
is
held
against
the
tool.
The
gauge
can be
part
of the
support.
11.
Chamfering
When
chamfering,
a
solid support
or a
tiltable adjustable spindle guard
fence
must
be
used.
A
woodpusher
must
be
used
for the
final
part
of the
machining.
