Methods of constructing orthodox carcasses with separate tops attached after assembly are shown in 188. Figure 188:1 shows the usual form of carcass dovetailing for a solid under top, 188:2 front and back bearer rail, 188:3 single dovetails screwed for extra strength, and 188:4 a solid top part dovetailed and part screwed. Where the carcass cheeks/sides are connected by rails only the intervening spaces must be filled with kickers shown by the dotted lines in 188:2A, which are pinned and glued to the carcass sides to prevent the drawer sides kicking
up between the rails as the drawer is withdrawn. Figure 188:5 shows the junction of a bearer rail with square post and grooved-in side or panelled frame, 188:6 a drawer rail stub tenoned in, and the drawer runner tongued to the front rail and housed into the sides. If the carcass sides are solid boards then the runners can be glued to the front rail but must be free to slide in the housing/dado as the shrinkage direction differs, therefore they must be fitted dry and secured at the back with a screw working in an open slot. Figure 188:7 is the normal stopped housing/dado joint for shelves which is usually sufficient if the joint is tight, but dovetail or taper dovetail housings can be used if the carcass sides have to be pulled in. Figure 188:8 shows the carcass base dovetailed as in the top (188:1).
