1paper, and throw the outline out of truth.) This is the pattern for the outline of the violin plates, and no pains must be spared to render it as perfect as possible.
3Now place the straight edge of this outline A A (Fig. 6) exactly along the centre line of the mould on the face side, allowing equal space to the edges, top and bottom, and go round the edge of the outline with a fine-pointed pencil and steel marking-point, leaving out the button B (Fig. 6). When complete, turn the half-outline over and exactly opposite the first half draw the other half, thus obtaining a facsimile of the complete outline of the violin on the face of the mould. Follow the sweep of the outline across the top instead of drawing in the button, which is not required in the mould.
5Now, as the ribs of the violin fit against the plates inside the edges, a second outline must be drawn inside the first to obtain the correct line to which the mould is cut out. With a pair of compasses draw the second outline \( \frac{5}{3} \) in. inside the first, jointing the lines in a point at the four corners B, as shown in the diagram (Fig. 5). The points should finish just at the edges of the corners and in the exact centre of each.
7The mould must now be cut out to this inner line, and the edge squared exactly all round from the face side of the block. A band-saw or fretsaw can be used for taking out the inside piece, leaving sufficient room for squaring to the line, which must be executed as carefully as possible. Remember that the violin is built in this mould, and that any defect in the mould will infallibly be reproduced in the instrument.
