INDOOR REMODELING 447 New doors are assembled with their stiles extending beyond the rails, forming "horns" which must be cut off before any measurements can be taken for fit. The sides can then be planed sufficiently to permit standing the door within the side jambs, after the spreader has been removed and replaced by the saddle. With the bottom of the door resting on the saddle and the top propped up or held tight against the head trim by a second person, a line can be scribed along the top rail from the other side. After measuring off the required clearance the correct amount of waste can be cut from the top, and the door fitted against the stops to determine the amount of planing required for side clearances. A slight bevel should be planed on the inside edge of the lock side of the door so that, as it opens, it will clear the jamb without binding. A convenient method for holding the door when planing its edges or mortising the hinges and lock is to construct a door jack as shown in Figure 9.5, consisting of two pieces of 2 X 6 or 2 X 8, nailed to a piece of lath and two pieces of scantling just far enough apart to receive the door when placed on edge. As indicated in Figure 9.6, after the door has been trimmed and planed, it is held tightly in its frame against the stops by means of thin wedges or splinters thrust into the three crevices. When all clearances have been satisfactorily adjusted, the placement of the hinges on the door edge can be accurately marked by placing the blade of a steel square against the trim and marking a short line where the tops and bottoms of the hinge mortises are located in the trims; or a very narrow chisel can be inserted in the crack between the door and the jamb to mark the mortises by wedging its sharp corner inward against the door. With a butt gauge or the half of a hinge, the mortises are scribed in the door edge, then chiseled out with an undercut edge as was done in the jambs. The hinge halves are then slid into place and holes for the screws bored with a spiral drill slightly to the rear, so that the screws, when driven Fig. 9.5. Door jack. Fig. 9.6.

If the lock to be installed is of the mortise type, it is a good time to bore out the series of holes that form the basis for its mortise while the door can be reversed in its jack. For the average adult the lock should be so located that the doorknob will be 3 ft. from the floor or bottom edge of the door. This can be assured by marking a short horizontal line on the center rail 3 ft.
