Hinging A Door. The hinges most commonly used in carpentry are the kind known as butts. Where the door stands in a vertical position, hinges in which the two parts are joined by a loose pin are generally used. By removing the pins the door may be removed without taking the screws out of the hinge. Such hinges are more easily applied than those with the fixed pin. (1) Place the door in position; keep it tight against the top and the hinge side of the frame. (2) Measure from top and bottom of the door to locate the position for the top of the higher hinge and the bottom of the lower hinge. Usually, the lower hinge is placed somewhat farther from the bottom than the higher hinge is from the top. (3) With the knife or chisel mark on both door and frame at the points just located, Fig. 135. (4) Take out the door, place the hinge as in Fig. 136, and mark along the ends with a knife. In a similar manner mark the frame. Make certain that the openings on door and on frame are laid off so as to correspond before proceeding further (5) Set the gage for the depth the hinge is to be sunk Fig. 137 and gage both door and frame. (6) Set another gage for width of openings, Fig. 138, and gage both door and frame, keeping the head of the gage against the front of the door. (7) Chisel out these gains on door and frame, Fig. 139. (8) If loose-pin butts are used, separate the parts and fasten them in place. Use a spiral drill to make openings for the screws. To insure the hinges' pulling tight against the side of the gain make the holes just a little nearer the back side of the screw hole of the hinge

Put the door in place and insert the pins. It is a good mechanic who can make a door hang properly the first time it is put up. It is better, therefore, to insert but one or two screws in each part of a hinge until the door has been tried. (9) If the door hangs away from the frame on the hinge side, take it off; take off hinge on door or frame, or both if the crack is large; chisel the gain deeper at its front. By chiseling at the front only and feathering the cut toward the back, the gain needs to be cut but about one-half as deep as if the whole hinge were sunk. If the door should fail to shut because the hinge edge strikes the frame too soon, the screws of the offending hinge must be loosened and a piece of heavy paper or cardboard inserted along the entire edge of the gain. Fasten the screws and cut off the surplus paper with a knife. If plain butt hinges are used the operations are similar to those just described except that the whole hinge must be fastened to the door and the door held in place while fastening the hinges to the frame.
