Full-size drawings or rods are necessary for setting out the work, showing the exact dimensions and constructional methods to be employed. Normally, design-drawings do not show the constructional methods unless they are of an unorthodox nature, and it is generally assumed that the furniture will be made in accordance with established custom; therefore the setter-out must decide the kinds of joint which will ensure adequate strength and rigidity in the construction, within the framework of the price factor and the designer's clear intention. In other words he must be a sympathetic interpreter, but at the same time completely practical in his approach.

Working drawings can be on paper, on sheets of plywood or on rods. The rods were almost invariably used in joiners' shops, and the lines were broken to condense the overall dimensions into a narrow pine rod about 9 in (228 mm) wide and 1/2 in (12.5 mm) thick. The method is useful for tall fitments, large bookcases, fitted wardrobes, panelling, etc., but a full-size drawing which is unmistakably clear is always simpler in the end. Figure 437 shows a fairly typical example of a full-size working drawing (reduced in scale for reproduction purposes only) of the cocktail cabinet described in Chapter 42. Figure 437:1 shows the front elevation, 437:2 the side elevation, 437:4A and B the plan halved on the centre-line to show the lower framing and the upper carcass with shaped interior shelf. Working details of the carcass construction, leg framing and lower shelf are shown in 437:6, door construction in 437:5, and drawer details in 437:7. Alternative methods of carcass construction and applied edgings are illustrated in 437:3, but in actual practice only one method need be shown.

In preparing working drawings the scaled dimensions of the original design-drawing must be followed and no allowance made for fair facing, etc. Thus a section shown as 3 in (76 mm)


722 V7777.

327 Laying out rods thick must be taken as 3 in (76 mm) thick finished section; whereas in joinery practice it is taken for granted that a specified dimension will conform to the standard sawn sizes for softwoods, or if shown as, say, 3 in (76 mm) by 2 in (50 mm) will in reality be ex sawn 3 in (76 mm) by 2 in (50 mm) or approximately 23/4 in (70 mm) by 1% in (44 mm) net finished thickness, unless expressly stated to the contrary.
