What are the basics of dovetail joinery?

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. Once glued, a wooden dovetail joint requires no mechanical fasteners.A dovetail joint is a series of overlapping, flared connectors that join two pieces of wood. The connectors are called tails and pins. When viewing the face of the board, the tails resemble a dove’s tail. So do the pins when viewing the end grain. The gaps between tails are called pin sockets, with the gaps between pins known as tail sockets.

What are the rules for a dovetail joint?

The shoulder line should be fractionally bigger (0.5mm) than the thickness of the wood to allow for a little overhang when the joint goes together. Mark out the two ‘half-pins’ at the edges on the first piece of wood. The ‘pins’ are the bits of wood between the tails so there are two half-pins; one each side.

What are the features of a dovetail joint?

Dovetail joints are known for their inherent strength and resistance to being pulled apart (tensile strength). A dovetail joint has a series of pins and tails in a trapezoidal shape and once glued a dovetail joint has no need for mechanical fasteners.

What are the standards for dovetail joints?

As a rule of thumb the dovetail’s maximum width should occupy approximately 1/ 2 to 3/ 4 of the gasket’s width (leaving a 1/ 4 – 1/ 8 of gasket width on each side). For larger gasket widths, multiple dovetails can be made side-by- side, facing the same direction or inverted.

How does dovetail work?

Dovetail joints, one of the strongest joints in carpentry, are woodworking seams that connect two pieces of wood by fitting them in with one another, similar to connecting two puzzle pieces. The end of one piece of wood is complementary to the other, creating an interlocking corner.

What are the features of a dovetail joint?

Dovetail joints are known for their inherent strength and resistance to being pulled apart (tensile strength). A dovetail joint has a series of pins and tails in a trapezoidal shape and once glued a dovetail joint has no need for mechanical fasteners.

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.

How difficult is a dovetail joint?

Hand-cutting a dovetail joint is kind of a woodworking high-wire act; one slip of the saw or chisel and the joint either won’t fit together or will look sloppy. It takes a lot of time to master the ability to cut dovetails quickly and well (by hand or machine), without a lot of fussing around.

What are the interesting facts about the dovetail joint?

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.

What are proper dovetail angles?

Although softwoods are more compressible than hardwoods, you needn’t change the dovetail angle to add strength to the joint. Any angle between 7° and 15° will work, regardless of the wood. But stay within that range. If you go below 7°, you’ll start to lose the mechanical strength of the dovetail.

What is the weakness of dovetail joint?

The disadvantages of dovetail joints are that they can be fairly difficult to mark out and cut, and if they are made badly these joints lose the advantages listed above. Depending on the project, function, and design, there are a number of different types of dovetail joints to choose from.

What is the most popular dovetail joint?

Single-lap Dovetail The single-lap (known to many folks as a half-blind dovetail) is the best known of the dovetails since it’s used to join the front to the sides of a drawer.

What is the most common 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.

What is dovetail in carpentry?

Dovetail nailing in timber is a woodworking technique used to join two pieces of timber together.

What are the advantages and disadvantages 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 is dovetail nailing and why do it?

Dovetail nailing grips both pieces of wood better than hammering the nails straight into the work. as the diagram shows, the nails are angled towards each other and this makes it a little more difficult for the two pieces of wood to be pulled apart.

What are the limitations of a dovetail joint?

The disadvantages of dovetail joints are that they can be fairly difficult to mark out and cut, and if they are made badly these joints lose the advantages listed above. Depending on the project, function, and design, there are a number of different types of dovetail joints to choose from.

How small can a dovetail joint be?

Structurally I have looked for pin strength in dovetails as the dovetailed aspect is always strong because it is always at least as wide and mostly wider than the pins. In my own work I aim for a minimum size of 1/4″ and mostly 3/8″.

What are proper dovetail angles?

Although softwoods are more compressible than hardwoods, you needn’t change the dovetail angle to add strength to the joint. Any angle between 7° and 15° will work, regardless of the wood. But stay within that range. If you go below 7°, you’ll start to lose the mechanical strength of the dovetail.

What is the standard angle for a dovetail?

Answer from the experts: Clearly, there’s no shortage of advice about the “best” dovetail angle: Some woodworkers recommend using 12° for “coarse work” and 7° to 10° for decorative joints.

What are the features of a dovetail joint?

Dovetail joints are known for their inherent strength and resistance to being pulled apart (tensile strength). A dovetail joint has a series of pins and tails in a trapezoidal shape and once glued a dovetail joint has no need for mechanical fasteners.

How tight should dovetail joints be?

If you can use your fist as a hammer to nudge them together, they’re just right. By the way, when you realize they will fit nice and snug, (hopefully by the time they are less than half way down) take them apart and don’t put them together again until you glue them.

Do you clamp dovetail joints?

No need for clamps if you dovetails are tight. I will clamp a board that may have bow a little. Don’t sweat the glue bond, a good dovetail doesn’t depend on glue for much of it’s strength. I bang them together with a rubber mallet.

Is dovetail joint permanent?

The strongest and most permanent right-angled joints made in wood are the ‘dove-tail’ joints, as illustrated below. The so-called tails and pins fit together to form a secure joint. Glue may be applied to the mating surfaces.

What is the most difficult woodworking joint?

Box joints and dovetails are the worst, because all the facets are visible, and not only must each dovetail or box tenon be perfectly sized, it has to also be perfectly located on the edge. The more the number of faces in a joint, the better the gluing area, but also the easier it is to screw up.

What are the hardest joints in woodworking?

What is the strongest woodworking joint? For excellent stability, the mortise and tenon joint is a great choice. It’s a relatively simple joint, yet it holds well. Woodworkers have been using it for generations because of its strength, versatility and simple design.
