I can custom make a coffee table to fit your existing table or I can make the legs as well. This listing is for the full table in the first pic. The base and top are custom to your specifications. These legs are 3" steel. I find the boards that are 100-150 year old barn wood boards and cut them to length, plane them, joint them with biscuits, glue them up, sand them lightly (to your specs if you wish) finish them with a Briwax finish, can bevel the edge or not,and put a brace on the bottom.
This listing is for a 5 foot by 40 inch table. Prices will vary depending on size.
