Door And Window Frames. Like other carpentry detail, window and door frames may be constructed in any one of a number of styles. Fig. 145 illustrates a satisfactory type of door frame for cottage use. The sill will be given a pitch or fall of I" in 12" and will have its ends housed into the jambs. The jambs will be assembled first, being nailed together. Next, the side casings are fitted at their lower ends, cut to length and nailed. Frequently they are nailed and then cut to length. The head casing with its cap is next placed.
Fig. 146 illustrates a common type of cottage window frame. The method of procedure is not unlike that described for the door frame. The sill will be grooved on its under side to receive the top edge of the siding board and given a fall of 1" in 10". Jambs must be grooved to receive a parting stop as shown. Where weights are to be used each jamb must have a pocket as detailed. The stock sawed out of the jamb may be made use of for pocket cover stock by proper manipulation. Pulleys may be placed before the jambs are assembled, at least the holes for them should be prepared.

There are a number of "tricks of the trade" in frame making.
Their presentation must be left to the instructor, for the making of frames belongs to millwork and space can be spared here for general directions only.
