Architectural Cabinetry Joinery: Used In All Parts Of Cabinet Construction Types Butt Joint The edge or end of one board butted up against another In simple form very weak Screws, dowel, and splines can be used to reinforce
Architectural Cabinetry Joinery Types Panel joints Join two or more narrow boards together into a larger panel. Used to make table tops, panels for frame and panel construction Edge joints Join the edge of one board to the face of another. Used in applying a face frame or trim to a cabinet carcass.
Architectural Cabinetry Joinery Types Frame Joints Join the end of a board to edge of another. Used to join rails and stiles in frame and panel construction Case joints Join end of one board to the face of another Used to make boxes cabinets and shelves.
Architectural Cabinetry Joinery Types Through joints: the parts of a joint can be seen as they pass through the other part of the joint Blind joints: the reinforcing elements cannot be seen
Architectural Cabinetry Joinery Types Reinforced Joints - element that adds strength to joint Dowel Butt joints Used for all four types of butt joints Can be pegged (dowels visible) or blind
Architectural Cabinetry Joinery Types Reinforced joint Spline Butt joints Spline joints use thin piece of wood called a spline The spline fits into a groove cut into the both mating surfaces of the joint Used for all types of butt joints. Most applications (except frame joints) as strong as dowel joints
Architectural Cabinetry Joinery Types Rabbet Butt joints Rabbet joint is a corner joint that has one shoulder Still needs reinforcement-nails or screws Usually used in L-shaped case joints on in edge joints
Architectural Cabinetry Joinery Types Rabbet Butt joints, Con’t Used to join the top of the cabinet to its sides; the back of the cabinet to the sides. When the back is placed in a rabbet the edge is completely hidden Shiplap is a variation used in panel joints Double rabbet is another variation
Architectural Cabinetry Joinery Terms Dado joints Dado is a T shaped case joint. Commonly used with rabbet joints in cabinet construction Dadoes are use do attach the shelves to the sides of the cabinet Because it has two shoulders the board is firmly held in place in three locations Variations are stopped Dados and dovetail Dados
Architectural Cabinetry Joinery Terms Tongue and Groove joints Made up of two parts the tongue and the groove Generally a panel joint. Maybe reinforced Can be used as a case joint to make either an l-shaped joint or a t-shaped joint
Architectural Cabinetry Joinery Terms Lap joints Lap joints are primarily frame joints Generally the lap is cut half way through one board, resulting in a flush condition. Not inherently strong and need reinforcement.
Architectural Cabinetry Joinery Terms Mitre joints Used where appearance is important Hides the end grain of both boards Can be a frame case or edge joint Mitre are weak joints and must be reinforced
Architectural Cabinetry Joinery Terms Mitre joints
Architectural Cabinetry Joinery Terms Mortise and Tenon joints One of the strongest frame joints the tenon is a projection on the end of one board that fits into a mortise on the joining board Mortise and tenon can be a blind joint or a through joint Use whenever a great deal of strength is needed
Architectural Cabinetry Cabinet Structure Types Frame and panel Skeleton frame Case construction
Architectural Cabinetry Cabinet Structure Types Frame and panel Traditional method of furniture construction Best construction method when using solid wood Accommodates the dimensional changes that occur with solid wood.
Architectural Cabinetry Cabinet Structure Types Frame and panel Frame construction Rails, stiles and mullions. Generally hardwoods - because exposed 1/2" thick and generally are 1 1/2" to 2" wide can be up to 4" wide Joined by using dowel, mortise and tenon or half-lap joints It then makes a plane that can be assembled with other frames to make the cabinet.
Architectural Cabinetry Cabinet Structure Types Frame and panel Panel Construction Solid wood pieces joined using edge joints such as tongue and groove, butterfly, dowel, or spline joints Grain matching is important. Panels are attached to the frame in a dado joint
Architectural Cabinetry Cabinet Structure Types Skeleton Frame Similar to frame and panel structure. Used for free standing furniture pieces Frame is covered with a thin skin of plywood or particle board or hard board instead of infilled with a panel This is similar to how houses are framed. The skin adds rigidity to the frame Quality of the frame and its joinery is covered with the skin.
Architectural Cabinetry Cabinet Structure Types Case Construction Suited to the use of plywood which is dimensionally stable The common joints used in this situation are dadoes and rabbet joints sometimes mitre joints are used as well Generally reinforced with splines, screws or dowels
Architectural Cabinetry Cabinet Structure Face Frame The face frame is a frame that is applied to the front edges of the carcass Generally important element of case frame structure as it hides the exposed edges of the carcass It also provides a solid attaching point for hinges.
Architectural Cabinetry Cabinet Structure Base Made of 2x4 lumber. (larger cabs ) Raises the cabinet off floor Provide space for the toe kick. Stretchers are beveled to provide stability on an uneven floor
Architectural Cabinetry Cabinet Doors Face Style Lipped Most inexpensive because of ease of installation Flush overlay Cover the face frame and have clean modern type lines Flush Flush are the most expensive type doors -most difficult to craft must fit the frame perfectly.
Architectural Cabinetry Cabinet Doors Types Flush - face is flat and continuous Raised panel - frame and panel type construction used. The panel may have center area raised Frame and Panel construction can also be used for glass doors as well Doors are subject to a great deal of warping. Be careful to specify stable material. 3/4 inch thick plywood minimum. Lumber core plywood best.
Architectural Cabinetry Cabinet Doors Drawers Construction Drawer is basically a box Constructed to have a very strong bottom and back and a front that can be pulled Installation Center glides Side glides Corner glides Tilt strip- not used with hardware guides, or side guides that use a dado cut into the drawer
Architectural Cabinetry Kitchen Cabinets Type Wall (upper) cabinets Base cabinets Sizes Codes specify minimum and maximum height, depth and clearance between wall and bottom cabinets Wall cabinets Typically 12" deep - 12-48" tall Base cabinets 30-36" high Width can vary (generally 3" increments 24" deep
Architectural Cabinetry Kitchen Cabinets Construction Classification AWI grades Economy Custom Premium All three grades use case frame construction Differences derived from quality of: - Materials used for exposed, semi exposed and concealed surfaces - Joinery - Thoroughness of construction
Architectural Cabinetry Kitchen Cabinets Construction Classification AWI Exposed Surfaces: Surfaces That Are Visible When: Drawers and opaque doors are closed Behind clear glass doors Bottoms of cabinets 42” or more above finish floor Semi Exposed Surfaces: Surfaces That Become Visible When: Opaque doors are open or drawers are extended Bottoms of cabinets are more than 30” and ales than 42” above finished floor Concealed Surfaces: Surfaces Considered Concealed When: Surfaces are not visible after installation Bottoms of cabinets are not visible 30” above finish floor Tops of cabinets over 78” above finish floor and not visible form an upper level. Stretchers, blocking, and components concealed by drawers.
Architectural Cabinetry • Kitchen Cabinets • Construction Classification • Materials For Case Frames • Plywood: • Hardwood (broad leaf trees) Softwood (conifers) • Three types: • - 5 to 7 veneer ply plywood • - Lumber core plywood • - Particle board core with hardwood veneer plywood • Surface quality is graded by how many imperfections per area • Grade 1 is best • Grade 3 is worst
