Wooden newel with a clean surface and preparation method thereof

A preparation method of a wooden newel with a clean surface, comprising the following steps:

• B1:
• preparing an inner core;
• B2:
• fixing multiple outer wood layers to an outer side surface of the inner core;
• and connecting the multiple outer wood layers in succession to form a closed structure, such that the outer side surface of the inner core is completely covered by the multiple outer wood layers, wherein an upper surface of the multiple outer wood layers is flush with an upper surface of the inner core;
• B3:
• fixing a top wood cover to the upper surface of the inner core and the upper surface of the multiple outer wood layers;
• B4:
• chamfering the top wood cover that extends along an upper surface of the top wood cover from a central apex of the top wood cover to a bottom surface of the top wood cover in one direction such that the top wood cover is uniformly chamfered;
• and
• covering an upper surface of the inner core and an upper surface of the multiple outer wood layer with the top wood cover.
