In February of 1981, I built 11 of these tables. The base is made from eastern Rock Maple, and the top is western Broadleaf Maple. The top came from a tree milled by a friend. The pattern is called "quilted". It is caused by the extreme weight of the tree crushing the lower section so much that the fibers are forced to ripple.
Gate legged tables were designed to take up minimum space when not being used, yet easily extended for company. The "gate" is a hinged leg, which folds into the central base when the top is down, yet swings out to support the top leaf when it is lifted up. The small drawer on the end goes all the way through the table, and opens from either end.
