Templates
To
duplicate turnings, you'll need a
template to follow. For a spindle turning
use either a flat template or
an
original
spindle.
(See
Figure
1.)
If doing a face-
plate turning (bowls or cups, etc.), you
must use a flat template only. Figure 2
shows a spindle template and the fin-
ished product. A faceplate template and
a side view of its product are shown
in Figure
3.
NOTE
You
can design your own templates
or find template patterns
in
wood-
working books and magazines.
When designing a template, keep in
mind the capabilities
of
the carbide
cutter(s) you own.
To
avoid problems
while you '
re
turning your project,
it's
a
good practice to use a detached fol-
lower to check your full size paper pat-
tern to
be
sure that the cutter will work
for all contours. For example, if your
template has a deep slot or V-groove, will
the cutter point go in far enough? If
your workpiece has a square in the
de-
sign,
be
sure that your template is
de
-
Signed so that the cutter doesn't
contact the rotating corners of the
square section.
Use
a suitable marking device to draw
the full size profile on the template
material or on white paper rubber
ce-
mented
to
the material. If paper
is
used,
it can
be
removed after cutting out
the template or left on. Each template
must have a permanently marked
cen-
terline and one or
two
end lines to indi-
cate the ends
of
the workpiece.
(See
Figures 2 and
3.)
The template ends to
be
clamped should
be
straight and
square.
Cut out your templates
on
a band saw
using the
1/8" or 1/4" blade. Sand the
sawn edges
smoothly using the pattern
files
on
the jigsaw, hand files, emery
board andlor sandpaper.
Your
completed
turning will be no better than the tem-
plate that it's copied from and you won 't
want rough spots to
be
duplicated.
