These include all doors that are made to order from the architect's drawings. They should be made of stock that has been well air-seasoned and thoroughly kiln-dried, and, if of hard wood, should be veneered on a pine core. The specifications should describe all particulars of their manufacture, and inch or |-inch scale drawings should be made, with the width of the stiles, rails and panels carefully figured. All mouldings and ornamental work should be drawn full size.
Solid doors are usually made in much the same way as stock doors, except that more care is taken with them, and they are kept perfectly dry. If the architect wishes to have the doors made in the best manner, he should also require that the tenons be made with haunches, as shown in Figs. 209 and 327, and that the panels be put in without bradding or gluing, as described in the following section. When the doors are to be made to order the panels may be arranged as desired, although the cost of the door depends largely upon the number of panels. For solid doors, and for ordinary veneered doors, an arrangement of panels like that shown in Fig. 218 is very satisfactory, as it makes a very strong and good proportioned door and the panels are not so wide as to cause excessive shrinkage. The two upper panels may be reversed, as shown by the dotted lines, if desired.
Fig. 224 shows a door having but a single panel, which may be used either as an inside door or as a front door. Figs. 225 and 226 show two designs for outside doors, the latter being cut in two horizontally, so that it is really two doors. This style of door is usually called a "Dutch" door. Doors with panels over 12 inches wide must be made with much more care than doors with narrow panels. The thickness of doors with large panels, such as is shown in Figs. 224 and 226, should not be less than 2 inches for doors 3 feet 4 inches wide and under, and 2 ¼ inches for doors over that width.
