Same Material, Same Craft: Replacement Materials Should Use Original Methods

A wooden component being replaced. The new timber's tree species and cross-section dimensions are identical to the original. The tenon and mortise joints follow the original form, and the surface is hand-planed to leave processing marks consistent with the old piece. No metal plates are used for reinforcement at the joints. The new piece's color is lighter than the old one. Avoid: using laminated timber and steel plates instead of wooden tenons, increasing the cross-section of the new piece for safety, using a smooth surface planed by machine, staining the new piece to make it look old.

一處正在抽換的木構件。新的木料樹種與斷面尺寸與原件相同,榫卯的形式照舊,表面用手工鉋修留下與舊件一致的加工痕跡。接合處不使用金屬板補強。新件的顏色比舊件淺。避免:改用集成材與鋼板取代木榫、把新件的斷面加大以求安全、使用機器刨光的平滑表面、把新件染色做舊。
