The tops of the square tables are made of three boards; one 18" wide flanked by two 11" wide.  The long tables consist of two massive 20" wide boards each.  The grain has been painstakingly aligned.  Much of the work involved in making a beautiful piece of furniture is considering the grain orientation of the lumber.  Most furniture shops give this aspect little regard. Here you can see the double bead edging which softens the corners and gives the table edge an inviting feel.

The column is turned in a tradition vase shape.  The legs attach to the column with a sliding dovetail joint.  For additional strength there is a steel spider attached to the underside of the base.
