    Abstract: A billiard table is enhanced by inserting an additional wood layer between the slate and the frame. Preferably, the additional wood layer is cut into two halves and placed on top of the frame such that there is space between the half boards. Slots are cut perpendicular to the longitudinal axis of the half boards to match the position studs on the interior beams. The angular table legs are enhanced by having the side boards of the legs cut at 45 degree angle at the connecting surface and creating a duct perpendicular to the connecting surface with a strip of wood glued into the duct running along the length of the leg. The table legs are further enhanced by inserting a strip of wood at the interior corner of the leg, forming a triangle with the two adjacent side boards. This invention reduces the overall cost of production.
