This is a slightly extended version of the fully evolved "Teepee" Table base I have been building and improving for 5 years. It is built in two flat halves (easy to ship) from 1 and 3/4 inch thick, hand-chosen black walnut and finished in Danish Oil and satin wax.
This base can be built in standard or extended versions to accommodate glass, wood (I build many of these), marble, granite, etc. tops from 36 to 60 inches in diameter. Please see many iterations and examples in my portfolio. These bases and tables are far and away my most popular item.
