LAYING OUT WORK

It is important to have the patterns placed correctly on the wood so

that the desired result may be reached. One of the things sought is

the greatest possible strength in the parts sawed out. The grain of

the wood should, therefore, run lengthwise of the wood where the parts

are narrow. Another thing desired is the economical use of material.

The patterns should, therefore, be so arranged on the wood that the

outlines will match closely together and thus use up as nearly as

possible all surface space on the board. Generally, it is advisable to

place the larger patterns first, beginning near a corner of the board,

and then fit in the smaller patterns on the intermediate spaces.

Where the drawings are not full size, the dimensions are shown in

inches or fractions of an inch. Guided by the figures, the outlines of

the object may be laid out directly on the wood by ruler, pencil and

compasses. In laying out the different shapes on the wood, attention

should be given to the direction of the grain of the wood, to have it

run lengthwise the object, not crosswise.
