I went to a recycleing place in seattle and found 6 oak 2×6'6s 12 ft long. That is what the main case stile and rails are made from. The panels are 1/4" blackwalnut and oak ply glued together. The doors are doorskins glued together. the archd top has 3 piece layered moulding. The dawer fronts are oak ply wraped in black walnut running on 100lbs slides. The drawers also have slinding trays with black walnut bottoms and all drawers are made of russian birch for stability.
