1A to point G, passing from one to the other by points B, C, D, E and F. The neck is then raised from the parchment, and the tracing is corrected as far as possible where it is not in conformity with the original.
3The compass is then returned to the parchment, at the places corresponding to those of the neck, the situation of the nut at the upper end of the neck is marked, and then the distance along the neck from the middle of the nut to the point C, and this, too, is marked on the parchment. The measurements necessary to establish the distance from the nut in question to the point AA and then to the point BB, are made in the same way. At point bb, one takes the measurements of every angle, figuring the degrees of distance from the spiral to the nut by straight lines which are set down on the parchment.
5When by means of these points the distance between the spiral and the nut at the upper end of the neck has been marked, the pencil should be used to trace the spiral, from point to point, and the model thus obtained. The parchment should finally be pasted on a piece of "model" wood and pierced with little holes.
7HOW TO PREPARE THE GLUE
9In violin making, glue, known as Cologne glue, is employed, taking its name from the city in question, where it is manufactured in the form of tablets of a very pale yellow color. This glue has the advantage of not forming a thickness between the pieces or parts which it unites.
11Since the various parts of which the string instruments are composed, are held together by this sole means, the first and indispensable necessity to this end is the obtaining of the best possible glue, and the taking of every precaution needful to prepare it properly.
13After having reduced the tablet of glue to fragments by means of a hammer, it is well to allow it to soak in water for the space of three or four hours; it should then be boiled in hot water. If one were to use an ordinary pot to boil it in, the glue, within a short space of time, would deteriorate; it becomes necessary, therefore, to secure from the proper source the special type of glue pot which is used by cabinet makers and joiners for hot-water boiling.
15In melting the glue, one must be careful to add water to it only little by little, and to add no more water than is absolutely required, so that, when it is completely melted, and one allows it to drop from the brush, it will appear to have the fluidity of a somewhat heavy oil. The glue should never be used save when it is really warm. The advantage which the hot-water gluepot offers is that of keeping the glue at the highest temperature possible without allowing it to burn.
17In his gluepot the violin maker always has a brush proportionate in size to the nature of the work he is doing, as well as a very narrow wooden spattle.
