1saw, filling up the saw-kerf with glue, and wetting the outside with warm water. There are four cross-bars glued on the inside of the back to strengthen it, each 1/2 in. thick, preferably of Swiss pine. They are rounded away on the top at the edges.
3The correct positions of these bars can be got by measuring Fig. 76 and comparing with the 1-in. scale in Figs. 74 and 75. The breadth of the three narrow bars is 2 in.; the bar nearest the neck covers the saw-kerf at the bend of the back, and the bar on which the sound-post rests is 3 in. broad. The rims are made of the same kind of wood as the back, and are 3/8 in. thick. They are bent by heat in the same manner as violin ribs, and made up with a pine lining at the edges to about 1/8 in. thick.
5The corner, neck, and tail blocks of the double bass should be of Swiss pine, with the grain at right angles to that of the ribs. The belly should also be of Swiss pine. It may be left almost 1/2 in. thick in the centre under the bridge, and thinned away to nearly 1/4 in. towards the edges. The rise is generally about 1 1/4 in., measuring from the back of the belly. The positions of the bass-bar and sound-post are seen at Fig. 76. In a four-stringed instrument, the distance between the centres of the strings at the bridge may be 1 1/2 in., at the nut it may be about 1 5/8 in. The height of the bridge is usually about 7 in.; its position is directly opposite the notches of the f holes, provided these in their turn are properly placed.
7Drawings for a violoncello can easily be prepared from the violin diagrams given on previous pages. The differences are wholly a matter of dimensions. For a full-sized violoncello make the length of body, exclusive of button, 29 in.; width across lower part, 17 in.; width across waist, 9 1/2 in.; and the width across the upper part, 13 1/4 in. The rough blocks for the back and belly would be about 3 in. to 4 in. high at the centre joint, but much depends on the model selected to build from. The ribs should be worked out to about 1 in. thick.
