Not illustrated. 1918 Excerpt: ...sent out into the yard. The lengths of plates for demand purposes are measured from the model, but the widths are taken from the body plans on the floor, due allowance being made for the width of the laps. It is usual to mark on the model on each plate the demand number and the size and poundage. The model will show to the yard people those plates which require "firing," and these can then be prepared in advance of the vessel being framed, and so delay may be avoided. Other models are lined out on similar principles to the above. A deck model would have the position of beams, bulkheads, plate edges and butts and openings shown on. An inner bottom model would have similar lines to those on the half-block model together with the position of the manholes. Expansion of Outer Bottom Plating.--Fig. 60 shows a specimen shift of butts arranged on a drawing known as the expansion of outer bottom. This drawing is practically a copy of the lines on the model, and it is made by first setting off the frame spaces to scale and drawing in lines square to a line representing the underside of keel. Measurements are taken from the model round each frame, all plate edges, flats, decks, etc., being marked and also the L.W.L. These girths are set out on the respective stations from the base line, and the spots on any one plate edge, etc., are connected by as fair a line as possible; thus the outer bottom edges are expanded. All the butts are copied from the model to the drawing; this forms a portable copy of the surface of the model. The expansion shown in Fig. 60 is for the fore end of a vessel of similar class to that for which the body has been drawn to illustrate the scrive board (see Fig. 45).
