One of the chief points to be observed in making a folding table of the kind shown by Fig. 79 is that the legs, which fold up against each other, should, when housed, be flush with, or a little way below, the flush of the rails, otherwise they are apt to be in the way. The dimensions given are suitable for a table which may be roughly used, but, for a light serviceable table, the scantlings may be reduced. The length of the top is 4 ft. 9 in., the height 2 ft. 6 in.; the width may vary from it to the position of the screw holes, and bore them. The angle and position of the screw are shown in Fig. 79, where a channel is seen cut out with a gouge, leaving a square shoulder for the head of the screw. After the top is screwed down to the frame the legs may be proceeded with. These are 3 in. by 3 in., and are made tapered on the inside edges from the bottom to about 1 in. below the frame. To allow the legs to fold up properly, a dead piece is screwed to the under side of the top at one of the ends. The thickness of this piece is deducted from the length of the legs. Rails
about 2 ft. upwards, according to requirements. The width and length of the top should be settled in order to get the exact size of the frame, to which it is screwed, and which is 2 in. smaller all round. This frame is dovetailed together at the corners and glued. To test the frame for squareness, place a wood rod diagonally from corner to corner and mark it. Try it on the reverse corners, and, if the mark coincides, the frame is square. This is a better method than using a try square, as the long rails might be bent somewhat, and this would lead to error. When the glue has set, clean off the sides and ends, and make the edges fair. Mark off, on the top edge, are mortised and tenoned into the legs at the top, and narrow spars are fixed in the same manner at the bottom. Flap hinges are used, and are screwed to the legs and top in the one case, and to the legs and fixed piece in the other. To hold the legs firm when down, small flush slip bolts should be let into them, the plate to receive the bolts being sunk in the rail. Another pair of slip bolts should be let into the outside edges of the rig^it-hand pair of legs, to keep them in their place when packed up. The dotted lines in Fig. 79 show the position of the legs when they are folded up. The scale of Fig. 79 is 1 in. to 1 ft.
