With regard to tongued and grooved joints which apply more particularly to the jointing of cabinet work, Fig. 93 is produced by planes which are specially made for the purpose. One plane makes the tongue and another the groove. The handiest sizes to buy are those which joint 3⁄8 in., 5⁄8 in., and 3⁄4 in. timber, it being usual to dowel or loose-tongue thicker boards. The 3⁄8 in. partitions (or, as they are sometimes called, dustboards) between the drawers of a sideboard or dressing chest are in good work jointed in this manner. The 5⁄8 in. and 3⁄4 in. ends and tops ofpine or American whitewood dressing tables, wardrobes, etc., call for the larger sized plane.
