In commencing to re-hair a violin bow, cut off the old hair and remove the mountings which held it in position, taking note as to how they are fixed. The wedge H (Pigs. 1 and 2) is picked out with the point of a penknife: the metal band G can be slipped off, and then the slide L will come away. The wedge D (Fig. 1) is picked out, and the knot of hair F will then come away. At the head of the bow simply turn up the ends of hair, pick out the wedge D (Fig. 3), and the knot of hair F will come away. The small wedges will probably be suitable for use again The hair is sold in bundles, each sufficient for one bow at 6d. to Is. per bundle. There will probablv be a knob of sealing-wax on one end as it comes from the dealer's which, when broken off, will reveal the ends tied with waxed silk, and cut pretty close to the tieing. In order to keep the ends from slipping out of this tieing, it is usual to sear them in a gas flame or on a red-hot wire taking particular care not to damage the silk tie, at the' same time cementing them together with a little resin. If the wedges have been destroyed in removing them, carefully fit a little piece of wood so that it will secure the hair in the box, as illustrated. The knot made on the end of the hair is now placed in the box at the head of the bow stick (Fig. 3), and fixed with the wooden wedge so that the hair comes away from the box in the form of a flat ribbon. The wedge is sometimes glued in, but this is not altogether desirable. If the wedge is shaped as illustrated, and properly fitted, it will hold quite firmly without glue, and will save trouble when the bow next requires repairing. The wedge must not fit too tightly sideways, or it will be liable to split the box. The hair must be combed through with a small toothed comb, then, coiling it up near the head, steep it for a few minutes in tepid water. Then comb again till it is a straight, flat band, all the hairs running parallel throughout their entire length. The nut B (Fig. 1) must now be set in the middle of its range of motion. Holding the band of hair in the hand over the opening in the nut, allowance must be made for the knot to curl round the wedge in the box, the hair tied with waxed silk, and the ends singed as before. This allowance cannot be measured in any way, but must be judged. Slip the metal baud G along the hairs to the top, and let it remain there. Take out the screw C entirely, thus allowing the nut B to come away from the stick; fix the knot of hair into the box in the nut exactly as was done at the other end, and replace the nut on the stick and try it for length. If it has been judged correctly, the hair will be too slack when the nut is at one end of its travel, too tight when at the other, and just right when it is in the middle. If correct, give it a final comb from head to nut, and replace the slide L (Fig. 1), which covers up the wedge box. Replace the metal hoop G and insert the wooden wedge H so as to flatten out the hair against the flat upper side of the hoop, and the job is complete. Fig. 1 shows the nut.
