T8.1 · CarcaseCarcase joints join wide boards or panels at right angles to form a box or cabinet: the sides, top, bottom and shelves. Examples are the housing, rebate, dovetail and scribed joints.T8.2 · CharacterTheir key characteristic is that they join the full width of a panel and support load across it, holding shelves and resisting racking so the carcase stays square.T8.3 · ShelfFor a fixed shelf, sketch a housing (trench) joint: label the trench, about one-third of the side's thickness deep, and the shelf end fitting in it. A stopped housing hides the joint at the front edge.T8.4 · Dovetail 1Dovetails are used in drawers because of mechanical strength: the flared tails and pins interlock, so the front resists being pulled off every time the drawer is opened, without relying on glue alone.T8.5 · Dovetail 2They are also attractive, showing craftsmanship and quality, and can be cut by hand or with a router jig for production.
