FACEPLATE
& CHUCK
TURNINGS
PLANNING
THE WORK
Make
a layout
first,
to provide
a visual
pattern
to follow
while
working
the turning
Patterns
can be laid out in the
same
manner
as spindle
patterns
-- or templates
can be
made
which
can
be
held
against
the
work
for
visual
comparison.
Circles
to locate the
various
critical
points
(at
which
the contours
of the faceplate
take distinct
form)
can
be quickly
scribed
on the
rotating
work
by
using
the
dividers.
PLANNING
VARIOUS
CUTS
The circumference
of a faceplate
t urning
is roughed-off
and
finished
in the
same
manner
that
a spindle
is worked,
Practically
all of the balance
of the operations,
however,
are
done
by using
scraping
methods.
A few of the standard
contours
which
must
often be turned
are illustrated
in the
accompanying
sketch
--
which
also
shows
the
proper
chisels
for shaping
these
contours.
Any
roughing-out
to
depth
that must be done is generally
accomplished
with
the
gouge
held in the scraping
position,
DEEP
RECESSES
The first
step
is to remove
as much
wood as possible
by
boring
into
the center
with the largest
wood bit available
This
can
be accomplished
as
illustrated.
Be careful
to
measure
in advance
the depth to which
drill can be allowed
to go,
BORING
TO DEPTH
Now remove
the buik of the waste
(to rough-out
the desired
recess) by scraping
w_ th the roundnose
chisel
or the gouge
Remove
up To within

of finished
size in this manner.
Finish
off the inside
circumference
by scraping
with
the
spear-point
chisel or skew,
Smooth
the bottom
of the recess
by scraping
it fiat with
the ftatnose
chisel.
Proper
support
must
be provided
at all
times
for
the
scraping
chisels
Severat
tool rest positions
are shown
in
the accompanying
illustrations.
Always
endeavor
to position
the part of the rest that
supports
the tool as close
to the
working
surface
as possible.
The depth
and squareness
of the sides of the recess
can be
quickly
checked
by holding
one of the straight
sided chisels
and a combination
square
as shown_
