Regarding the fingerboard: The optimal size is a total length of 270 millimeters, an upper width of 24.5 millimeters, a lower width of 42.5 millimeters, an edge thickness of 4.5 millimeters, a surface insulation of R42 millimeters, and a longitudinal concavity of 0.7 millimeters

The height of the high opening panel should be determined as follows: a straight line extends from the top of the panel to the installation position, so that the distance from the panel is 27 millimeters. Or the height from the end of the panel to the height of the panel, with an ideal height of 21+-1

If the dimensions of the components are exactly the same, A board should pass through a 158 degree angle.

Regarding the rope: The length from the top of the panel to the rope pillow is 2, and the length from the top of the panel to the adjustable horse (small fgap) is 3. Calculation shows that the length from the top of the panel to the rope sleeper should be

nm

It should be 130 millimeters, and the length from the top of the panel to the installation horse (small hole f) is usually 195 millimeters, which means the effective rope length is 325 millimeters.

Center distance: GDAE is evenly distributed on a 5mm thick flat plate with a center distance of 11-11.5mm.

At the end of the finger pad, the electronic rope is located at a distance of 2.8-3 millimeters from the height of the finger pad. The height of the G-line is 5-5.5 millimeters, the height of the E-line is about 29 millimeters, and the height of the G-line is about 31 millimeters

Meter, AD line naturally bends (D line slightly higher)

Sea cucumber holes can improve cardiovascular health, and horse legs can increase sensitivity. Removing the tip of the drooping wing can increase the transparency of the sound. Removing the tip of the nose is beneficial for symphony performance, and raising the arc is beneficial for sound. Regarding horses: the thickness of the horse's legs is 4.5-5 millimeters, and the tips of the arms, hips, and feet should not be less than 5mm, and the waist should be less than 15mm. Expanding the foramen can improve the development of the AD string and expand its propagation

Relatively speaking, the thick bottom plate has fine pores, small pores, coarse pores, and hard materials. Material for the design of sound columns: It is recommended to choose wood such as Imm, Primavara, Toasta, Lemn Greu, and Moacle, usually using white sapin thread. It is best to choose wood with a hardness of over 5 bar. Thickness: The diameter range is 5 to 6.5 millimeters. The high radius of the plate can be slightly thicker, and the low line can be slightly thinner. Thick columns suppress vibration, while thin columns allow for free vibration. If the plate is thinner or has a flatter curvature, the support force of the thin plate is greater. Turn up the volume a bit and make a change. We need to make it easier to set up the pillars. Tilt angle: The curvature of the tilt angle should be the same as the curvature of the panel and backplate, so that the contact surface between the panel and backplate forms a "surface" rather than a "point"; The annual rings intersect with the annual rings of the panel, that is, they are perpendicular to each other. Horizontal position: Close to the base bundle, the base will be better; Getting closer to the drainage hole will improve the drainage effect. Vertical position: Leave 2-3 millimeters or more at the lower edge of the saddle, and the thick plate should be kept away from the rear of the saddle; Thin plates should be closer to the front of the saddle. Other components:

The length of the rope should be 1/6 of the effective length of the rope, which is 55 millimeters, between the horse head and the towing plate. Do not use or use less than the amount that may be used
