[EN] Using CNC technology and hide glue to restore a fretboard seamlessly. [中] 利用 CNC 技術配合傳統皮膠，製作同材質木栓進行無縫填補，是古董結他修復與指板翻新的關鍵紀錄。

Picture 1: Clean the wood filler inside the fretboard's circular hole.

Picture 2: Based on the size of the hole, use a CNC machine to create cylindrical inlays from wood with the same diameter.

Picture 3: Mix wood dust into hide glue, matching the color of the fretboard. Then, use the hide glue to adhere the cylindrical wood inlays to the fretboard.

To be continued...

One fine day, we received the guitar neck shown in Image 1.

Well... How can we turn it into the finished product like in Image 2?

Do any of you have any ideas?
