the roughed-off cylinder, you can quickly mark the various
points of the critical diameters. To make each sizing cut, use
outside calipers and set these by actually measuring the
length of the vertical line on the pattern which represents
the diameter desired. Then make the sizing cut, down to the
proper diameter by using the calipers to determine when
the cut is finished. After making the sizing cuts, hang the
pattern behind the lathe where it will serve as a guide for
completion of the workpiece.
Using a Template and a Diameter Board
When many identical turnings are to be produced, it is a
convenience to have aprepared template. Thiscan be made
of thin wood or cardboard -- and is cut on a band saw or
scroll saw to have the exact contour ofthe finished turning.
The number one finished turning can also be used as a
template. Attach the template to a board; then mount the
board behind the lathe, on hinges, so that the template can
be moved down to touch the workplace and allow you to
closely observe progress ofyour work.
USING A
TEMPLATE
USING A
DIAMETER BOARD
tf a great many turnings are being produced, a diameter
board will save the time used for resetting calipers, This is
simply a thin board along the edge of which a number of
semi-circular cuts have been prepared to represent all the
various caliper settings required for measuring the sizing
cuts. Each semi-circular cut is held against the workpiece
instead of using the calipers.
USING DIAMETER SIZING GAUGE - 24909
Production work can be further speeded by the use of the
Diameter Sizing Gauge - 24909 to take the place of caliper
measurements, The positions of the ar ms are set to indicate
the various sizing cuts to be made. Each arm is of such a
length that it will drop all of the way down past the back
side of the workpiece when the wood under it has been cut
out to the desired depth of the sizing cut.
USING COPY CRAFTER - 24907
To make identical spindles for chairs, table tegs, or to
exactly copy an existing turning the Copy Crafter -24907 is
used, Follow the outline of original turning or template and
the cutting tool duplicates the workpiece. Spindle turnings
up to 2-1/2 inches in diameter, 36 inches long can be
duplicated from original turnings; up to 6 inches in diameter;
36 inches long from a template. Shallow faceplate turnings
up to 8 inches in diameter can be duplicated fi:om templates.
LONG SPINDLES
A long turning can be worked in short sections, with joints
arranged to be at shoulders where they will not be noticed.
Long thin work that is likely to whip while turning should be
supported at one or two places by a backstick. This is easy to
make. A Simple one consists of a short length of wood
mounted vertically in an extra tool rest, and notched so that
it can be used to support the spindle from behind. An
improved type -- which uses 2 roller skate wheels to form
the notch -- also is shown.
