Stock that is to be laid
out in other than a geometric design requires the use of a pattern.
A pattern is a full-sized outline of the shape to which the material
is to be cut. It may be made of paper, cardboard, thin wood, or
metal. The way in which a pattern is placed on the stock will depend
on how the pattern is laid out. When the pattern has been properly
placed on the stock, it is traced onto the wood.
A piece of stock which must be symmetrical
(with its opposite sides shaped identically) requires the use of
a half-pattern. When such a pattern is used, a center line must
be drawn on the stock to establish the location of the pattern;
then the pattern is placed on the center line. The outline of the
pattern is marked on the surface of the stock with a pencil.
Then the pattern is turned over and placed
on the other side of the center line, and the outlining of the pattern
is repeated. A pattern that does not require the use of a center line
is shown. Such a pattern is the complete outline of the shape to which
the stock is cut.
The stock is cut to a rough outline by the use of
a coping saw or compass saw, by sawing a little outside the line to allow
sufficient material to smooth the sawed surfaces.
