A dovetail joint is a joinery technique used in woodworking, traditionally used to join wooden furniture. Dovetail joints are known for their inherent strength and resistance to being pulled apart (tensile strength).Noted for its resistance to being pulled apart, also known as tensile strength, the dovetail joint is commonly used to join the sides of a drawer to the front. 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. The pins and tails have a trapezoidal shape.
Why is a dovetail joint good?
The advantages of the dovetail joint are that it is the strongest of all joints, has a large gluing area, is interlocking, resists being pulled apart, looks attractive, and would hold together even without glue.
What are the rules for a dovetail joint?
The general rule is that they measure half the thickness of timber plus around 1 mm along the shoulder line. So these two awl dots are 7 mm in from each edge. These two dots, which mark the corners of the half pins, are now converted into a 1:8 slope at each side.
Are dovetails the strongest of all joints?
Dovetail is arguably the strongest joint in millwork. It’s made so that it can’t be twisted or pulled in any direction except for one. This means that it’ll take more force to break or damage the joint. Because of the preciseness of each piece, this joint is held into place without the need for extra reinforcement.
How does dovetail work?
A dovetail joint is essentially a series of wedges cut into the long grain of the wood. The tails and pins (opposing wedges) hold the joint against the forces of gravity and being pulled, pushed or otherwise separated. A well cut dovetail will hold fast, even without glue.
Why is a dovetail joint good?

How old are dovetail joints?
While dovetail joints can be found on ancient Egyptian coffins from 3000 BC, they were not used in European and American furniture until the mid 1600s. Dovetails have flared tails like a bird on the end of the drawer’s side boards that interlock into mirroring pins on the drawer’s face board.

Should dovetail joints be glued?
Michael Dresdner: The only areas that require glue on dovetails are the diagonal faces. All the diagonal faces are long grain, all the square faces are end grain, and all the flat faces abut end grain. Therefore, you need only apply glue to the diagonal faces on the tails or pins, or both.
Is dovetail joint permanent?

So the angle of the dovetail mainly depends on the use and wear the joint will get. 5. They are called ‘dovetails’ because they are shaped like the tail feathers of a dove!
How is dovetail made?
A dovetail joint is made by cutting interlocking parts on two pieces of wood. The tail board has the dovetails. The pin board has pins that slide in between the dovetails. Each outer edge of the pin board has a half pin, meaning only one face of the pin is angled.
Why is the dovetail joint the strongest joint?
The dovetail joint is very strong because of the way the ‘tails’ and ‘pins’ are shaped. This makes it difficult to pull the joint apart and virtually impossible when glue is added.
What are the pros and cons of a dovetail joint?
The interlocking dovetail joint has a large gluing area, further adding to its strength. Hand cut dovetail joints require precise handsaw and chisel skills, and can be fiddly to mark out and cut. If dovetail joints are poorly made they will lose the advantage of strength and durability.
What are the advantages of dovetail nailing?

What is the best dovetail angle?
Percy Blandford, who has been writing about woodworking for a long time, writes in “The Woodworker’s Bible” that any angle between 7.5° and 10° is acceptable. The ideal, he says, is 8.5° for softwoods and 7.5° when joining hardwoods.
How tight should dovetails be?
