Double Margined Entrance Door

Double Margined Doors are wide single doors so framed as to appear pairs of doors. They are used in openings too wide proportionally for a single door, but where half the opening would be rather small for convenient passage

These doors are made in two ways. In the earlier method, the middle dividing stile, which in this case is constructively a munting, is made in one piece, and forked over the top and bottom rails, which are continuous.

The intermediate rails are stub tenoned to the middle, and through tenoned and wedged to the outside stiles, but unless the stub tenons are fox-wedged, the shoulders are very liable to start, for which reason the method of construction now to be de¬scribed is generally preferred.

The door is composed of two separate pieces of framing each complete with two stiles and a set of rails that are tenoned through and wedged up. The two portions are then united by a ploughed and tongued and glued joint, which is hidden by a sunk bead in the centre, as shown in the detail, f. 1 adjacent, and the parts keyed together with three pairs of hardwood folding wedges. The door is sometimes further strengthened by having flat iron bars sunk and screwed into the top and bottom edges. The actual process of putting the door together is as follows:—After the various rails and panels have been duly fitted and marked, each leaf is taken separately and the stiles knocked on. The one intended for the meeting stile having been glued, is cramped up and wedged. Then the meeting stiles are shot to a width, grooved, jointed, and rebated for the beads, as shown in the detail, f. 4, above. The ends of the tenons and wedges should be cut back in. to prevent them breaking the joint when the stile shrinks. The mortises for the keys will have been made when the mortises for the rails were done, and cross tongues are next glued in, the joint rubbed, the two stiles pinched together with handscrews, and the oak keys, well glued, driven in. At this stage the frames are stood aside to dry, after which the projecting ends of the keys are cut off, the panels inserted, and the two outside stiles glued and wedged in the usual manner. After the door is cleaned off, the grooves to receive the beads are brought to their exact size with side rabbit and router planes. Should iron bars be used, they are inserted in grooves made after the door has been shot to size. The bars should be about £ in. shorter than the width of the door, so that their ends may not be visible when the door is brought to size.
