Continuing from the previous post:

Picture 1: Use a chisel and a scraper to remove most of the protruding wood.

Picture 2: Sand the fretboard, starting with coarse-grit sandpaper and gradually progressing to finer grits.

Picture 3: Finally, polish any scratched frets and apply fretboard oil.

And there you have it, all done!

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?
