Doors are of two kinds - ledged and panelled. The former is less difficult to make than the latter; in fact it requires more skill to make the latter kind of door than you would well acquire, so we will give directions for making a ledged door. Every door must have a frame, which consists of two side-pieces called the "jambs" (a, Fig. Go), and a lintel, 6, which is generally halved into the jambs, and a sill, c, into which the lintels are generally mortised. The simplest kind of ledged door consists of boards, the edges of which come flush together, and are secured to the rail either by screws or nails. A better door would have the boards grooved and tongued, as in Fig. 65, d, and then secured to the ledges, which sometimes have diagonal braces added to give greater strength. The hinges, both the size and kind, must be determined by the weight and the size of door.
