The method of making a music box is as follows:

Prepare materials: hand grinder, wood block, sandpaper, and hacksaw.

Operation steps:

1. First, we use a hacksaw to cut a section of wood to make a cube, and use an electric grinder to dig out a round hole with a diameter of about 100MM in the middle of the wood block.

2. Then slowly sand it smooth with sandpaper, and smooth the bottom of the wooden block with sandpaper.

3. Cut a small log to make a positioning pin, and glue the bottom disk to the cube wood.

4. Finally, use tools to make the preliminary shape and polish it.
