400-year old hackberrywooden hadmade sopatable in koreasawmill

I made a living room seat table out of a 400-year-old korea hackberry wood that came into my sawmill, and I put it on a large scale, and I made it about a year and a half later.
Koreahackberry has a piece of furniture that people used for furniture.
The biscat joiner was used to collect the tops, and to prevent bending, the panels were inserted into each side of the rim in a tight shape.
thank you.
