Having selected a suitable piece of wood it must be cut or planed square and equal in thickness. It should be as nearly the right length as possible before being placed permanently in position, the ends being very tough in cutting. If by miscalculation they are found to project over the width of the fingerboard, they should be—when the glue is quite dry—cut through with a small bow saw close up, a gentle, careful filing will reduce them down level with the side of the fingerboard; the surface should run easily with that of the peg box, which is not always of the same width as the other, the arching can then be proceeded with, a chisel being first used, then a rather close grained file for further levelling and the finishing off with the finest glass-paper or emery cloth, having a drop or two of oil in it; this will give a smooth, dull polish agreeable to the eye. The grooves in which the strings will have to rest must be marked out or pricked to measurement so that the spaces may appear regular when the violin is strung up. The distance apart being occasionally done to the caprice of the player, measurement should be kept of this matter of detail from some well regulated instrument as a standard to go by. When the exact spots for the grooves are marked or pricked, a very small, round or "rat-tailed" file may be used to work the wood down at the spot, care being taken that the file is constantly held in an exact line with the direction of the fingerboard, otherwise when strung up the appearance at the part will be that of distortion and the string will even be checked in its freedom in passing through the grooves, each of which should be made to receive the string not too tightly nor too loose. Of course the width of each groove must be in agreement with the thickness of the string, the widest being the D, the G a little less, the A less still and the E least of all; the E should be a trifle closer to the fingerboard than the D or G, the last, having the widest swing during play, should be raised further off the board than the others. The arching of that side of the nut may also be left a little higher. The nut should also be made to slant down towards the peg box (diagram 8), the grooves being of a regular depth on this and not deeper at the top (diagram 9). When all is ready for the stringing up, a soft lead pencil may be used for blackleading the grooves, they are otherwise liable to arrest the progress of the string towards the pegs when tuning up and suddenly letting them go with a click, making the tuning uncertain and difficult; if the wood is rather obstinate—it is not always alike—a touch of beeswax of the size of a pin's head where the lead is placed will be an effectual cure.

We may now leave this as finished, going to the other end of the violin where another nut is used for supporting the tail-string as it comes over to the end peg. This part is frequently done in a slovenly way, even by some repairers of good repute; there is no reason why it should not be as neatly done in all respects as any other part. It may be that the supposition is uppermost in the mind of the repairer that, like the nut at the fingerboard, the pressure of the strings will retain it in position. This is a mistake, there is a great pull forward, especially if the wood is hard and dry. The material should be selected for its solidity and hardness like that for the other nut. In olden times, say those of the early Italians, this part, owing to the small amount of strain in consequence of low pitch, low bridge and short neck, seems to have been treated with almost indifference, a very slight piece of ebony, cherry, pear, or other variety of hard wood found in Italy, sufficing for the purpose (diagram 10). It was left level with the surrounding soft wood, or nearly so; there was no occasion for raising it at the time, as the tail-string projected from the underneath of the tailpiece instead of that almost universally now known as the secret tie (diagrams 11 and 12). This latter necessitates the use of a higher and more substantial nut, otherwise the tailpiece would be close down to, if not touching, the table, causing a rattling. Further, in accordance with mechanical law, the strain or pull forward increases with the height of the nut. It is therefore obvious, that unless well fitted and held strongly, the nut will be liable to be wrenched forward out of position. This is more frequent than would be suspected, and is sometimes a secret source of damage or bad influence leading to disaster in other parts of the instrument. The same observations concerning the preliminaries apply to the fixing of this as to the other nut. The modern arrangement of the part leaves but little to be improved upon.

The length and thickness of the nut required having been determined upon, we will suppose ourselves in the presence of an old worthy from Cremona requiring a fresh attachment, the wood selected—Mauritius ebony for preference—and the measurement as follows, 5/16 in length and thickness according to the width of the border, as the nut looks best when the inner edge runs in a continuous line with that of the purfling (diagram 13). In highly finished work and when the end of the violin has a perceptible curve instead of being nearly straight, the nut should be made to follow the course of the purfling, this will require some care in the cutting and finishing of it. For this a piece of almost any veneer cut to the exact flow or drawing of the line may be used as a guide or template. The block from which the nut is to be made having been cut quite level, the line can be traced with a fine pointed pencil, or better, a fine pointed knife, and then shaped with a sharp chisel. The block or nut can now be laid on the border, care being taken that the tail pin comes immediately in a central position in relation to it, and then with the sharp pointed knife a finely cut line can be traced all round. The space now marked may be cleared away down to the top of the end block with a clean, vertical wall on three sides formed by the pine. If carefully done, the nut, at present only a solid, squared block, will fit exactly, if too tight, a little shaving off here and there of the pine will correct it. The nut, supposed to be an exact fit, may be warmed and some fairly strong glue applied (diagram 14). The raw surfaces of the pine and the exposed end block are of course very absorbent and require an extra feed or two in order that the final glueing of the nut and place of reception may have a good holding. The nut, now squeezed into position, will not require the clamp, but if time is no desideratum an application of that useful tightener will ensure a firm hold, and moreover the superfluous glue is forced out.

DIAGRAM 13. DIAGRAM 14.

When the glue has had time to thoroughly dry and harden, the clamp may be released, and a part at each end of the nut marked off for levelling down to the surrounding forces by filing and glass-papering. The manner and care with which this is done declares the excellence and characteristics of the workman or firm by whom he is employed; almost every repairer or house of reputation having their individualisms in this respect, as also in that of the fingerboard nut (diagram 15). A line having been ruled with precision along the upper central part with the pencil or knife as before, a small gouge can be run along a hollow which will face the bridge. To give this the best kind of finish a piece of pine or soft poplar, such as is used for champagne wine cases, you may look out for one about Christmas time, cut it to the shape of the part to be finished thus (diagram 16), and with a piece of fine glasspaper, slightly oiled, a few rubs backwards and forwards will be necessary. The top of the back part can now be shaved gently down by a small metal plane, a little filing will give the evenness and rotundity required. The same treatment will be necessary for the under part, which in good work is a continuation of the line of the edging of the upper table. A section of the nut in its finished state will be as in diagram 17.

The whole of the surfaces may now be finished with the finest emery cloth and oil. This latter may be linseed, nut, poppy or castor oil with turpentine, but do not use sweet or olive oil, it never dries, but lurks about in the pores of the wood and turns rancid.
