What are the rules for dovetail joints?
The space between half pins is divided between pins and tails. Fine work the pins 4mm > 6mm, larger work 7mm > 12mm. To have a desirable appearance the pins smaller than the tails. Your tails should be around 18mm > 35mm for fine work like drawers and 35mm > 55mm on larger work like a chest.
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.
What is the spacing for a dovetail?
There should be roughly one dovetail each 25mm or so across the width. There’s no hard and fast rule so it’s up to the woodworker to use his or her judgement to decide how many are needed.
How deep should a dovetail joint be?
Typically we use 1 ½” – 2” deep dovetails that are about 2” less deep than the joist, and 4” less deep than the girt – but that is just a starting point – the loads and reactions have to be calculated from there.

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.
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.
Are dovetails the strongest of all joints?
Methods. 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.
Are dovetail joints worth it?
This adds extreme strength to the drawer box joints. It is almost impossible for the joints to break because of the dovetail cuts as well as it being made from solid wood. In addition to this, most companies will also add the full extension, undermount, soft closing drawer guides.
Which part of a dovetail do you cut first?
Cutting the dovetail pins first makes sense. It’s easier to hold the pin board in place to mark the tails than it is to hold the tail board against the end of what will be the pin board. Also, the walls of the pins provide a good surface for the awl as you mark the tails.1 Feb 1996
Is 11mm dovetail the same as 3 8?
However, that is not the only difference between the two dovetails. They also have different groove angles as shown below. The 11 mm dovetail has a 60-degree angle, while the 3/8” dovetail has a 45-degree angle.
What is the ratio for a dovetail joint?
Dovetail angles are usually expressed as ratios — the most common being 1:6 and 1:8 (said “one in eight,” and also written as 6:1 or 8:1). As a general rule of thumb: Use 1:6 for softwoods. Use 1:8 for hardwoods.
Is a finger joint stronger than a dovetail joint?
For box joint, some people put a lot more fingers than it is possible to do with Dovetail. In this case, the gluing surface is larger, and the joint is likely stronger. Also, some find a way to hide a finish nail in the joint. Dovetail has the advantage of a mechanical lock independent of the glue.
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 best dovetail angle?
Lower (7° to 9°) angles are often advised for joining hardwoods, while higher angles (10° to 14°) are recommended for softwoods and even higher angles (14° to 18°) for half-blind dovetails.
What are the important information of dovetail joints?
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 is the standard angle for a dovetail?
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 dovetail ratio?
Dovetail angles are usually expressed as ratios — the most common being 1:6 and 1:8 (said “one in eight,” and also written as 6:1 or 8:1). As a general rule of thumb: Use 1:6 for softwoods. Use 1:8 for hardwoods.
What is the minimum thickness for a dovetail?
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 the rules for dovetail joints?
The space between half pins is divided between pins and tails. Fine work the pins 4mm > 6mm, larger work 7mm > 12mm. To have a desirable appearance the pins smaller than the tails. Your tails should be around 18mm > 35mm for fine work like drawers and 35mm > 55mm on larger work like a chest.

Do you need to clamp dovetails?
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.
Can you make dovetail joints with plywood?
A wide variety of methods can be used to make dovetail plywood drawer boxes. They are generally considered by the woodworking industry as time-consuming and difficult to make. The dovetails can be cut by hand with a dovetailing saw and chisel or you can use a dovetail jig and router.
Are dovetail joints 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.
