General cabinetry including kitchen cabinets
Parts Of Cabinets
Joinery: Used In All Parts Of Cabinet Construction
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
Join two or more narrow boards together into a larger panel.
Used to make table tops, panels for frame and panel construction
Join the edge of one board to the face of another.
Used in applying a face frame or trim to a cabinet carcass.
Join the end of a board to edge of another.
Used to join rails and stiles in frame and panel construction
Join end of one board to the face of another
Used to make boxes cabinets and shelves.
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
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
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
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
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
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
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
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.
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
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
Frame and panel
Frame and panel
Traditional method of furniture construction
Best construction method when using solid wood
Accommodates the dimensional changes that occur with solid wood.
Frame and panel
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.
Frame and panel
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
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.
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
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.
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
Most inexpensive because of ease of installation
Cover the face frame and have clean modern type lines
Flush are the most expensive type doors -most difficult to craft must fit the frame perfectly.
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.
Drawer is basically a box
Constructed to have a very strong bottom and back and a front that can be pulled
Tilt strip- not used with hardware guides, or side guides that use a dado cut into the drawer
Wall (upper) cabinets
Codes specify minimum and maximum height, depth and clearance between wall and bottom cabinets
Typically 12" deep - 12-48" tall
Width can vary (generally 3" increments
All three grades use case frame construction
Differences derived from quality of:
- Materials used for exposed, semi exposed and concealed surfaces
- Thoroughness of construction
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.
