琴腔規劃與內部預挖

古琴面板和底板之間的鏡像映射構成古琴內部特殊的發聲結構，所以面板和底板之間的構圖規劃精度也決定了古琴的性能。而面板的兩個納定位在四到七徽之間以及十到十三徽之間。但在加工成型以前為求兩板之間的映射精確，就需要先在底板進行全面開孔，再以臨時合琴情況下勾畫出面板的納音定位。

在底板的開孔和麵板的構圖完成後，就可以進行初步挖槽腹處理，讓面板進一步因應自然乾縮而產生定量誤差，並為下一步的安裝配件工期提供更穩定的基準面。

The mirror designing between the soundboard and backboard constitutes the special resonate structure inside the Guqin, so the designing accuracy between the soundboard and backboard also determines the performance of the Guqin. The two boards of the Qin are positioned between four to seven emblems and between ten to thirteen emblems. However, in order to achieve accurate designing between two boards before crafting and tunning, it is necessary to finish all drilling in the backboard before, and then outline the resonate structure positioning of the soundboard under the condition of temporary bounding.

After the backboard drilling and soundboard resonate structure designing are completed, preliminary digging inside the Guqin and let the soundboard enter natural shrinkage and steady out a certain deviation, and provide a more stable reference baseline for the next progress of accessories embedding.
