Hello friends of Bali Interio, joint is a minimalist concept that originally emerged from Zen, the Japanese philosophy of minimizing distractions in order to focus more on paying extraordinary attention to detail and the connection of one of these details in the manufacture of furniture, especially furniture made of wood, rattan or bamboo.

In the world of carpentry, a connection is a combination of two elements of wood with certain techniques to get a more complex shape. In addition to the wood itself, wood grafting techniques can also involve bolts, screws, glue and so on. In addition to adding strength, today’s joints are often exposed to improve the visual quality of the furniture design itself. Each carpentry work in some respects has its own connection characteristics, for example, the connection for furniture with techniques in buildings has various differences.

The main factor in making a connection is strength, therefore one of the things to consider in making a connection is the direction of the wood grain. Incorrect grain direction can lead to wasted connection making. Here are some of the basic types of joints we commonly encounter in carpentry.

butt joint

This connection is the most basic wood connection that brings together the two ends of the wood at a certain angle. These joints require glue or screws to strengthen them. Often in furniture products knock down with the help of a fisher at the end of the wood that will meet the end of the coupler. To get a perfect angle, the pieces of wood on one or both of the wood must be perfectly shaped so as to eliminate gaps that can reduce the strength of the connection. Also known as a sweet joint.

Dado Combination

This joint is a simple type of T joint, providing a gap in the board so that the verticals can fit the horizontal boards inside. This joint usually combines glue and strategy for strength. With gaps or trenches in a part of the board, the T-joint made is stronger than the regular tail-joint because it doesn’t slide easily.

Rabbit Joint

This connection is a type of L connection located at the end of the wood. It has better strength compared to the regular tail connection but requires more effort. Both rabbet and dado connections usually use a router for their manufacture in order to get precise, clean, and consistent results.

finger joints

This connection is an extension of the tail joint type. So that the strength is built in a well balanced way in each wood as well as in each gap. The strength of this connection is higher by one level of connection dado and rabbet and can be exported using either two or one type of wood.

Pass Connection

This joint is one of the favorite joints in furniture making. Can be exposed by using two different types of wood materials so that the color of each wood provides a blend of contrasting color differences. In terms of strength, this joint is an improvement over the finger joint because it locks at one point of tension as well as changes in angle. Compared to the past, using either a bench or a hand router is now much easier because the manufacture of router bits (router bits) of various sizes are made. Dovetail consists of three types namely full, half and shear. Sliding dovetails are usually used to make T joints.


Dowels are cylindrical pieces of wood that are plain or threaded to function as holding the two pieces of wood together and installed like pegs by applying glue beforehand. These joints can be exposed to show off and the strength of the joints made with this technique. Dowels can also be used as a complement to other connection techniques to have a level of strength one level above it.

Pocket Connection

This joint uses the force to join two pieces of wood by creating a slanted path to insert it. After locking the two pieces of wood, usually the resulting hole will be covered with wood putty to ensure that when it’s finished there’s no space that doesn’t look good. To make a hole with an accurate slope and the same as the others, a certain jig is usually used.

Half Round Joint

This connection uses each half to get the desired angle with the aim that the strength is evenly distributed in the two wood materials that are joined. These joints can also be used with glue or solutions, but in certain sizes, these joints with precise measurements can strengthen other joints in more complex constructions.

Tongue joint

Using a router, tongue joints are usually used to make large plank sheets from joining the boards on the sides. For example, to make a door leaf or a table top from solid wood boards. This connection usually uses glue as reinforcement and then presses using rope, technical glue or other pressing each edge so that the gap between the boards is completely closed. This connection is like connecting the bottom of the letter T with the letter U.

Mortise connection

This connection is made by inserting part of one piece of wood into a hole in the other. The holes and ends of the wood made for these joints are usually squares made using a bench mortice tool that can make box holes. Although it can be re-strengthened with styling or dowels, usually the use of wood glue is sufficient and does not result in other exposed materials. This connection technique we usually encounter in old wooden chairs.

Biscuit joint

This connection to make a wide wood can also use biscuits together. This connection is a wood edge connection by making paths or holes on both sides of the wood and tucking the wood in the holes between the wood. This method usually uses thinner pieces of wood that are stronger than the base wood. For example, to tuck in between mahogany, use teak wood and so on with wood glue.
