How to mount the chin rest of the violin, unilateral

The gill mounting method on one side of the violin is as follows:

The violin pawrest, also known as the paws, is an accessory installed in the middle of the strings of the case panel, which is fastened by the paillary shaft. It plays the role of pressing the cheek rest with the left lower jaw to stabilize the body, protect the paint on the surface of the panel from being worn, and more importantly, the chin rest screw buckle is fixed on the edge of the back plate, while the chin rest itself should not be in contact with the panel and string plate, otherwise it will affect the pronunciation.

Violin chin rest.

The wood used for the chin rest is the same as the pimple and the pin plate. Strictly speaking, all three accessories should be made of the same wood in order to harmonize the violin's exterior tone.

1) Materials. The chin rest had to be made of the same wood as the pins, plates and tail sleepers, and the colour of the lacquer had been taken into account in order to harmonize with the colour of the violin. Some parts of the cheek rest are relatively thin, so hard wood should be used, and the wood used is nothing more than ebony, jujube, mahogany, poplar, boxwood, and colored wood.

2) Kind. There are two types of cheek rests commonly used, one is the bridge cheek rest, which is installed with two feet straddling the strings. The advantage is that when the chin rest screws are tightened, most of the pressure between the two feet of the chin rest and the screw bracket is added to the tail wood block between the panel and the back plate, thus reducing the pressure on the fragile side panels.

Another type of chin rest is mounted on the left side of the lower end of the violin, and apparently the lower side plate on the left side takes all the pressure. Due to the influence of climate and sweat, the supporting strength of the side plate will be reduced, and it is easy to deform the side plate or cracks.

3) Installation and production.

The selected wood is sawed into blocks of 100 mm long, 60 mm wide and 26 mm thick, and then the front and side contours of the cheek rest are copied on the block, and the line is sawed along the positive contour line with a small saw, and the side contour line is the basis for filing, and the shape of the gills is basically processed with a knife, chisel and file, and then polished with various types of sandpaper, and finally wiped with linseed oil or engine oil, so that the ebony shows its dark nature. Boxwood can be dyed black with dyes, and jujube wood and colored wood can be colored with dilute hydrochloric acid or dilute nitric acid. Finally, at the rear end of the two feet, drill a positive buckle screw hole according to the size of the spacing of the cheek screws.

The underside of each foot is covered with a padding made of leather or cork in the same shape to protect the panel.

Try it in a few directions yourself, and most of them will know how to be safe.

Summary. The violin jaw shaft is made of metal, and its function is to stabilize the chin rest, also known as the chin rest screw at the tail of the violin. The cheek hook hangs on the edge of the back plate, and the panel is the chin rest, which is properly tightened and stabilized on the panel to prevent it from shaking at will.

But don't tighten it too hard and properly, too much force will damage the panel part. One side of the backplate is also cushioned to avoid damaging the edges of the backplate.

The gills of the violin are made of metal, and its function is to stabilize the cheek rest, also known as the cheek snail to sell dry silk at the tail of the violin. The gills hook hangs on the edge of the back plate of the hole and the panel is the cheek rest, and the cheek rest is properly tightened and stabilized on the panel to prevent it from shaking at will. However, if the bridge is not matched, it should be tightened too hard and appropriately, and the panel will be damaged if the force is too strong.

One side of the backplate is also cushioned to avoid damaging the edges of the backplate.

There are two types of gills, one is a foot screw that is connected together, and the other is called a foot screw, as the name suggests, such a gills shaft does not have a bracket that is connected into one, and the two screws are separated. The advantage is that the distance between the two screws can be flexibly adjusted, and the disadvantage is that the installation is more annoying, and it is necessary to groove the bottom of the hole in the cheek foot, and insert the base of the upper buckle screw, and fix it with small screws. The base of the lower screw is thicker and protrudes beyond the back plate, which will be slightly felt at the collarbone if the player is wearing thin clothes.

There are some special places in the structure of the gill shaft, that is, when Liangzhou rotates the nut, the screws at both ends can be retracted or withdrawn from the nut at the same time, so the screws at the upper end are buckles, and the screws at the lower ends are buckles. In this way, when the nut is rotated clockwise, the screws at both ends are indented into the nut to achieve the purpose of tightening the cheek slip; Rotate the screws at both ends counterclockwise to release the cheek rest. The parts of the jaw shaft are all metal machined parts, and there are also professional manufacturers who provide products, so there is generally no need to make them yourself.

The violin is placed on the left side of the oak barrier, and if Qi presses the string with his left hand, he <>

On the left you can violin**.

a): The bottom of the cheek rest should fit perfectly with the top of the instrument.

b): Note that the smaller the contact point with the body, the better, so the double support screw is more popular than the single support screw, because the smaller the contact point, the less vibration that hinders the body.

c): After installation, the angle of the cheek rest should be straight, especially not upturned.

d): Be sure to tighten the screws, otherwise the body will make noise.

This is caused by a mistake in the way the piano is held, and it is probably the result of self-study.
