In woodworking, joints are one of the most important aspects all workers should be good at because almost all project has a specific type of joint. joinery is a part that that involves joint together pieces of wood or lumber to produce more complex items. The purpose of wood joints is to provide strength, flexibility, toughness, appearance etc. to the project. So, your joints should offer these characteristics. Some wood joints use fasteners, adhesives, or bindings while others use only the wood elements.
Today we’ll be looking at the definition, types, purpose, tools as well as the advantages and disadvantages of woodworking joints
What is a wood joint?
Wood joints is a woodworking process that is performed to join pieces of wood together in order to create complicated parts. There are different techniques used when producing joints depending on the type of wood joint to be produced. For instance, the method used to construct house joinery can be different from that used to make cabinet joint, though some concept can overlap.
Types of woodworking joints:
Below are the various types of wood joints you can use for your projects:
- Butt Joint
- Biscuit joint
- Bridle joint
- Dado (joinery)
- Dovetail joint
- Finger joint
- Lap wood joint
- Mortise and Tenon joint
- Pocket-Hole joinery
- Rabbet joint
- Tongue and Groove joint
Let me explain in details
A butt joint is the easiest and weakest joint to create in woodworking which is done by butting two pieces to wood together. Some reinforcement is added to increase the joint strength but it depends upon glue to hold the workpiece together.
This joint is nothing but a reinforced butt joint with an oval-shaped piece. Generally, a biscuit is made of dried and compressed wood like the beech used in both pieces of wood in matching mortises. Well, most people use a biscuit joiner when creating matching mortises where accuracy is not important. This joint is design to allow flexibility in glue-up. One of the limitations of this joint is that it is not perfectly aligned and mistakenly cutting the mortises for biscuit joiners.
The woodworking joint is similar to a mortise and tenon joints: Tenon is cut at the end of a workpiece and a mortise on the other to create the joint. There are three glueing surfaces as it provides good strength in compression and is moderately resistant to racking making suitable to house a rail in upright such as legs. Bridle joint uses a mechanical fastener or pin for additional strength.
A dado joint is used to attach shelves to a bookcase carcass which is rabbet to the dado. It is a slot cut into the surface of a piece of wood. it has three sides when viewed in cross-section and it passes all the way through the surface and its ends are open. A dado can be cut perpendicular to the grain.
This woodworking joint is a very strong joint with great tensile strength (ability not be pulled apart). It is often used to connect the sides of a drawer to the front. The joint is permanent when glued and requires no mechanical fasteners. A series of pins cut to extend from the end of one board interlock with a series of tails cut into the end of another board. This pins and tails have a trapezoidal shape.
The finger joint is one of the most popular woodworking joints also known as box joint. it is used to join pieces of wood at right angles to each other. The joint is much similar to dovetail joint only for the pins that are square and not angled. Finger joints do not have the mechanical strength of a dovetail and it relies on glue to hold the joint together.
Lap wood joint:
The joint is attained by removing half part of the material from each piece in order to get the same thickness of the piece which is known as half lap joint. The half-lap joint is the most frequently used joint which workpiece must have the same thickness. The joint is good for creating workshop storage items.
Mortise and tenon woodworking joints:
Mortise and tenon joints are one of the strongest joint perform in a carpentry shop. It is normally used to join two pieces of wood at 90-degrees, one end of the piece is inserted into a hole in the other piece. The end of the first workpiece is called a tenon and the hole in the second piece is a mortise. Glue is used in this joint and pin or wedge may be used to lock it in place.
This joint is also one of the most popular woodworking joints, more like a butt joint with pocket hole screws. Two drilling operations is required, first is counterboring the pocket hole which takes the screw head contained by the piece. The second drilling is the pilot hole whose centerline must be the same with the pocket hole. This pilot hole allows the screw to pass through one piece to the adjoining piece.
Rabbet woodworking joint:
This joint is recess cut into the edge of a wood piece. it is two-sided and open to the end of the surface when viewed in cross-section. A rabbet joint is used in the back edge of a cabinet which allows it to fit flush with the sides. It is also used in the insertion of glass pane by using the rabbet around the edge of the frame.
Tongue and groove joint:
Another popular woodworking joints are the tongue and groove joint, used in wood flooring, parquetry, panelling, etc. one of the workpieces has a slot (groove) cut and the other piece has a tongue cut on the mating edge. With this, two or more pieces can be closely fit together. The joint can be cut in numbers of way.
Benefits of wood joints:
There are various advantages of woodworking joints on projects making them inevitable two use. The following stated below are the benefits of wood joints:
- It offers rigidity to jobs.
- Enhance job appearance.
- Make the parts stronger.
- Mechanical fastener and adhesives are used.
- Joints can be easily disassembled using steam to soften the glue.
- Fasteners and glue can be used together to make the joint stronger.
- A properly glued joint may be stronger than a single piece of wood.
- Joints can be designed without the use of glue or fastener.
