ANATOMY OF A FRAME-AND-PANEL ASSEMBLY

Bottoms and tops are usu­ally added, along with shelving in many cases. These components are typically made of edge-glued boards of the same stock used for the frame.

Individual cabinets will feature vari­ations. In some instances, the sides will share stiles with the front and back assemblies with rails fitting into both the edges and the faces of the stiles. To pro­vide access to the inside of the cabinet, the front frequently has a frame but no panel. Sometimes, a median rail is used to divide the opening into two discrete sections.

The two most common joints in ffarne – and-panel cabinets are the haunched mortise-and-tenon and the cope-and- stick. The haunched mortise-and-tenon offers greater gluing surface than the standard mortise-and – tenon, making it a very strong joint. The haunch also fills in the end of the groove cut into the stiles, eliminating the need for stopped grooves. The cope-and-stick joint provides comparable strength and adds its own decorative touch. The router bit that cuts the grooves for the panel also carves a decorative molding in the inside edges of the frame. Whatever the joint, cabinetmakers usu­ally build frames from 14-inch stock that is at least 2 inches wide; larger stock may also be used to suit the dimen­sions of a particular project.

Usually overhangs outside edges of frame; attached with wood buttons, as shown, or with metal fasteners, ledger strips or pocket holes. Edge commonly has routed decoration

Molding

Conceals joint between top and frame; can be purchased or made in the shop

‘Hood button

Used to fasten top to frame. One end fits into groove cut into frame, permitting slight movement; other end screwed to top

Shelf support

Can be positioned in dadoes at any height inside cabinet to provide adjustable shelving

Shelf

May have decorative detail rout­ed along front edge
