I have a customer here on custom made that had an old wine barrel that want to make it into a table and storage unit. I made the top for him using purpleheart, paduck, cherry, quina, maple, ash and walnut. All the colors are natural and will just age not fade.
On the bottom of the table i put in a grove so that the top will just sit on the stays of the barrel.
the table is 28" round
