Top 12 Wood Working Joints to Know About


Joinery is a part of wood working that involves joining pieces of wood, to produce more complex items. A few wooden joints hire fasteners, bindings, or adhesives, while others use only wooden elements. The characteristics of wooden joints – strength, flexibility, toughness appearance, etc.- derive from the properties of the materials involved and the purpose of the joints. Therefore, different joinery techniques are used to meet different requirements. For example, the joinery used to assemble a house may be unique from that used to make puzzles and toys, even though some principles overlap. In British English usage it is distinguished from carpentry which relates to structural timber work.

Many wood joinery techniques either depend upon or compensate for the fact that wood is an isotropic: its material properties are different along different dimensions. This must be considered while becoming a member of wood elements collectively, in any other case the joint is destined to fail. Furniture from the 18th century, even as made by means of master craftsmen, did not take this into consideration. The result is this masterful work suffers from broken bracket feet, which was often attached with a glue block which ran perpendicular to the base pieces. In modern woodworking it is even more critical, as heating and air conditioning cause major changes in the moisture content of the wood.

Materials used for joining

  • Joints can be designed to keep without using glue or fasteners; a pinned mortise and tenon is an example of this.
  • Glue is powerful for joining timber when both surfaces of the joint are edge grain. A properly glued joint can be as sturdy or more potent than a single piece of wood. However, glue is extensively less effective on quit-grain surfaces.
  • Various mechanical fasteners may be used, the most effective being nails and screws. Glue and fasteners can be used together.


Below are the given joints which are mostly used by the wood workers:


lap joint

A lap joint or overlap joint is a joint wherein the individuals overlap. Lap joints may be used to enroll in wooden, plastic, or metal. A lap joint may be a full lap or half lap. In a full lap, no material is removed from both contributors a good way to be joined, resulting in a joint that is the blended thickness of the 2 members. In a half of lap joint or halving joint, material is eliminated from both members in order that the resulting joint is the thickness of the thickest member. Most commonly in half lap joints, the members are of the same thickness and half the thickness of each is removed. With respect to timber joinery, this joint, in which long-grain wood faces are joined with glue, is the most powerful in ability to withstand shear forces, exceedingly even mortise and tenon and other commonly known “strong” joints.

briddle joint closeA bridle joint is a woodworking joint, much like a mortise and tenon, in that a tenon is reduce on the quilt of one member and a mortise is reduce into the opposite to just accept it. The distinguishing function is that the tenon and the mortise are reduced to the entire width of the tenon member. The corner bridle joint (additionally referred to as a slot mortise and tenon) joins contributors at their respective ends, forming a corner. This form of the joint is generally used to house a rail in uprights, together with legs. It provides good energy in compression and is resistant to racking, although a mechanical fastener or pin is frequently required. The bridle joint is very popular in workbench creation. A variant of the bridle joint is the T-bridle, which joins the quilt of one member to the middle of another. The T-bridle joint is very sturdy and accurate for joining 2 pieces collectively.

dovetail closeA dovetail joint or dovetail is a joinery technique commonly used in woodworking joinery (carpentry), which includes furniture, cabinets, log buildings, and traditional timber framing. Stated for its resistance to being pulled apart (tensile strength), the dovetail joint is generally used to sign up for the sides of a drawer to the front. A series of ‘pins’ reduce to extend from the stop of one board interlock with a series of ‘tails’ cut into the cease of any other board. The pins and tails have a trapezoidal form. A wooden dovetail joint requires no mechanical fasteners. The dovetail joint could be very sturdy due to the manner the ‘tails’ and ‘pins’ are shaped. This makes it hard to drag the joint aside and genuinely not possible while glue is introduced. This form of joint is utilized in container structures such as drawers, jewelry packing containers, cabinets, and different portions of furnishings wherein energy is needed. It is a difficult joint to make manually, requiring skilled workmanship.

tongue and grooveTongue and groove is a technique of fitting similar objects together, edge to edge, used specially with timber, in flooring, parquetry, paneling, and comparable constructions. Tongue and groove joints allow flat portions to be joined strongly collectively to make a single flat surface. Earlier than plywood became common, tongue and groove boards had been extensively utilized for sheathing buildings and to assemble concrete form work. It is one of the strongest joint and is widely used for re-entrant angles. The impact of timber shrinkage is hiding while the joint is beaded or otherwise molded. In luxurious cabinet works, glued dovetail and a couple of tongue and groove are used. Every piece has a slot (the groove) cut all alongside one area, and a skinny, deep ridge (the tongue) on the alternative edge. The tongue initiatives a bit much less than the depth of the groove. Two or extra pieces thus suit together intently. The joint is not normally glued, as shrinkage would then pull the tongue off.

mortise and tenonA mortise (or mortice) and tenon joint connects two portions of wood or of different material. Woodworkers round the world have used it for thousands of years to sign up for portions of wooden, mainly when the adjacent portions connect at right angles. Mortise and tenon joints are robust and solid joints that can be used in lots of projects. The miter joint is consisted to be one of the few most powerful joints after the common dovetail joint. They provide a robust outcome and join through either gluing or locking into location. The miter tenon joint also offers an attractive lookout. One drawback to this joint is the difficulty in making it. As requires tight and precise cuts. In its most simple shape, a mortise and tenon joint is each simple and sturdy. There are numerous variations of this kind of joint, however the simple mortise and tenon incorporates two additives: the mortise hole, and the tenon tongue. The tenon, formed on the end of a member commonly known as a rail, fits into a rectangle or rectangular hollow cut into the alternative, corresponding member. The tenon is cut to match the mortise hollow exactly. It commonly has shoulders that seat whilst the joint completely enters the mortise hollow. The joint can be glued, or pinned to lock it in location.

butt jointA butt joint is a way wherein two pieces of material are joined by way of genuinely placing their ends together with non special shaping. The name ‘butt joint’ comes from the manner the material is joined. The butt joint is the only joint to make because it simply involves cutting the wood to the right duration and butting them together. It is also the weakest due to the fact until a few forms of reinforcement are used it is predicated upon glue alone to hold it together.

butt joint example


finger jointA finger joint, also called a comb joint, is a woodworking joint made by using cutting a set of complementary, interlocking profiles in two portions of wood, that are then glued. The go-section of the joint resembles the interlocking of fingers between two arms, therefore it is called “finger joint”. The perimeters of each profile increase the floor region for gluing, resulting in a sturdy bond, more potent than a butt joint but not very visually attractive. Finger joints are regularly confused with box joints, which might be used for corners of bins or box-like constructions.

finger joint example


dowel jointDowel joints are very strong and appealing if like several different joints constructed properly. Dowel is also very useful for substantially growing the energy of weaker woodwork joints inclusive of the butt joint. This form of joint is secured with an adhesive and a small piece of dowel. Construction additionally calls for nothing more than a drill and a few accurate markings. To acquire ideal markings a unique measuring device may be used to measure the position of the holes for the dowel to be inserted. The device is referred to as a dowel center and they are placed in a pre drilled hole to create a correct mark on the alternative piece of timber where the following hollow will be drilled. In this joint dowel are glued and inserted into holes instead of screws. By way of using dowel over screws the joint turns into an awful lot more potent and can be changed into an attractive feature.

secret mitered dovetailThe ‘secret mitered dovetail’ joint (additionally referred to as a ‘mitered blind dovetail’, ‘full-blind dovetail’, or ‘complete-blind mitered dovetail’) is used in the maximum magnificence of cupboard and box work. It offers the energy determined inside the dovetail joint but is completely hidden from each out of doors faces via forming the outer edge to meet at a 45-degree perspective even as hiding the dovetails internally with in the joint.

biscuit jointIn contrast to some of the different joints cited biscuit joints are one of the much less used woodwork joints. That is specifically because there are not many places wherein this type of joint is more beneficial than any other form of joint. As its name shows biscuit joints are secured with pieces of wood which are inside the form of a biscuit and those pieces of wooden help to prevent movement and add strength. To construct these joints, you want to use a device called a biscuit joiner that is used to cut the biscuit fashioned holes in the wood. This joint is especially used to sign up for big timber boards together along with those you will find on tabletops and it’s also aesthetically attractive if the joint is tight. As mentioned above the biscuit formed pieces of timber assist to prevent the massive timber boards from moving.


dado jointA dado is a slot cut into the surface of a piece of wood. While viewed in cross-section, a dado has three faces. You cut a dado perpendicular to the grain. It is far unique from a groove, that you cut parallel to the grain. A through dado passes all the way through the surface and its ends are open. A stopped dado has one or each of the ends prevent earlier than the dado meets the edge of the surface. You use dadoes to connect shelves to a bookcase carcass. You rabbet the shelves to fit in shape of the dado, which makes the rabbet and dado joint. It is a good joint used for woodworking.

dado joint example


halve jointA halved joint is a woodworking joint wherein the two parts are joined by removing material from each member at the point of intersection so that they overlap. The halved joint is differentiated from the lap joint in that the members are joined on side, instead of on the flat. The simple halved joint is created by cutting a slot in opposite edges of the individuals to be joined so that they slip collectively. Most usually, the quantity of material eliminated is identical to 1/2 the width of the part being joined, although this depends at the relative dimensions of the member. This joint is rather weak and prone to splitting, due to the dearth of shoulders which could otherwise save you twisting.
