Fitting A Door. The names of the parts of a door and their relative positions are indicated in Fig. 132. (1) Mark with a try-square and saw off the lugs, the parts of the stiles which project beyond the rails. (2) Plane an edge of the door until it fits the side of the frame against which it is to be hung. If the frame is straight, this edge may be planed straight. It is not wise to take for granted the squareness or straightness of a frame. A test or series of tests may first be made with square and straight-edge. A mechanic, however, usually planes an edge until it fits the frame, testing by holding the door against the frame as near to its position as its size will allow. (3) Measure the width of the frame at its top and bottom, Fig. 133, and transfer these dimensions to the top and bottom of the door, Fig. 134. When approaching the line, in planing, place the door against the frame often enough to see where the allowances must be made for irregularities in the frame. (4) Plane the top edge of the door until it fits the frame properly when the first planed edge is in position. (5) The length of the door will be determined by scribing it to the floor after being hinged.

The edge of the door which is to swing free is usually planed slightly lower at the back arris than at the front. An examination of the movement of an ordinary house door will show the reason for this.
