In the most satisfactory construction the backs of corner carcases are framed together, the advantage being that they are ntt liable to shrink.
- Plan of corner cupboard with paneled backs. Top and bottom are of plywood or block board.
- Corner cupboard using solid front rail.
- Alternative arrangement with front rail rebated to receive plywood filling.
Of course, if ply or block board is used there is no difficulty. Note that pilasters are invariably introduced, partly to give increased rigidity, and because they help the design. It is always advisable to allow them to project a trifle at the sides towards the wall then, If the wall is not perfectly square, there will not be a gap showing at the sides. In the best work they are rebated or tongued to the backs, and the top and bottom are dovetailed in.
It will be seen from that the top is screwed into rebates in the back frames and is dovetailed to the pilasters. Such a top should be of ply or block board because it will not shrink against the rigid end frames. An alternative is to have a solid front rail dovetailed in with a ply filling at the back, fitting in a rebate in the rail as in Fig. 18. Assuming that the ply is thinner than the rail, the end frames will have to be cut down to finish level with the rebate.
Perhaps the commonest arrangement today is to frame up the two backs, covering them with 4mm ply or hardboard, either inside or outside, according to design. These frames are screwed together at the back corner and screwed also to rebated pilasters at the front. At the front too a frame is fitted between the two pilasters. As this frame is usually fairly light it is generally ad-visable to retain square upright edges and work the entire bevel on the pilasters. It also has the advantage of simplifying the screwing. In any case, temporary blocks are glued on, as shown by the dotted lines, to enable the joint to be cramped. Top and bottom are of multi-ply screwed on. Generally an applied molding hides the joint at the front edges.
Corner stands. Small corner tables or stands for corner cupboards have sometimes to be made, and their construction depends largely upon the leg positions. When the stand is bow-fronted the side rails are tenoned into back and front legs. As the front rail would necessarily show short grain if tenoned it is generally more satisfactory.
- Corner cupboard construction with front frame. Inset is a plan section of one front corner.
- Plan and details of stand for bow-front corner cabinet.
- Plan of corner stand with legs at extreme sides.
- Corner cupboard stand with legs set in from the corners.
Since most rooms are fitted with a skirting it is invariably necessary to arrange for the cupboard to project at the sides of the stand. In the case of a table small blocks are screwed on outside as at A, and the top kept level with this. The top thus reaches right through to the walls although the legs clear the skirting. If the cabinet above is straight at the front and the legs have to be at the extreme sides, the front rail can be shaped in plan as shown in Fig. 22 and be doweled in. Strengthening angle brackets can be added inside. Note the filling blocks added at the outsides of the legs opposite the rails.
