Finger jointed boards: a row of interlocking wood fingers

A close-up of a wooden box corner, with all four corners finger-jointed: the ends of two boards are each cut with equally wide square protrusions, interlocking to form a regular grid pattern around the corner. Because the wood grain directions of the two boards are different and their colors also vary slightly, the interlocking parts show clear alternating light and dark patterns. The width of the fingers is the same as the board thickness, a traditional proportion. The outer corner has a minimal 1mm chamfer, smooth to the touch but visually still sharp. The surface has a thin layer of shellac. Close-up oblique angle. Avoid: fingers of inconsistent width, large rounded corners, two boards using the same piece of wood making the interlocking invisible, using plywood for finger joints.

一個木盒轉角的近景,四個角都以指接處理:兩片板材的端部各切出等寬的方形凸出,互相交錯咬合,形成一排規律的方格圖案繞著轉角。因為兩片板材的木紋方向不同、顏色也略有差異,交錯處呈現清楚的明暗相間。指的寬度與板厚相同,是傳統的比例。轉角外側做 1mm 的極小導角,手摸不刮但視覺上仍是銳角。表面上薄薄一層蟲膠。近距離斜視角。避免:指的寬度不一、轉角做大圓角、兩片板材使用同一塊木料看不出交錯、使用膠合板做指接。
