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 best ratio for dovetails?
As regards the ratio to use on various woods, dont get your knickers in a knot. Anything from 1:6 to 1:9 looks good and works well. Too little rise leaves corners with short grain that easily breaks off, too much rise looks like a poorly made box joint.
What is the standard size of a dovetail?
11 mm and 3/8” dovetails are the two most common types of dovetails that you can find on rifles. The 11 mm dovetail represents a standard in Europe, while the 3/8” is a standard in the USA.
What is the most common dovetail angle?
Percy Blandford, who has been writing about woodworking for a long time, writes in his new book, “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 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 a 1 8 dovetail ratio?
A 1:8 ratio – one unit horizontal with eight matching units drawn vertical – is an angle of 7.1 degrees. I doubt woodworkers in the last century had as strong a passion for being precise as woodworkers today. In fact, my guess is that most 18th- and 19th-century woodworkers simply picked up a saw and went at it.
What makes a dovetail joint so strong?
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.
What are the rules for dovetails?
Which is better English or French dovetail?
While both English and French dovetail construction are very sturdy and high quality, English dovetail construction is slightly sturdier with the trade-off of being more expensive and time-consuming to produce.
Is dovetail the highest quality?
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.
What are the traditional 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 are the weaknesses of dovetail?
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 ratio of 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.
Should you glue dovetail joints?
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 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.
What is the formula for measuring dovetails?
To obtain dimension x for measuring male dovetails, add 1 to the cotangent of one-half the dovetail angle α, multiply by diameter D of the rods used, and add the product to dimension α.
What is a 3 8 dovetail?
3/8″ dovetail rails, sometimes call tip off rails, consist of two thin parallel grooves and are used almost exclusively on rimfire rifles and air rifles. 3/8″ dovetail rails are a common, standardized style within the rimfire industry and are inexpensive to machine into the firearm’s frame.
Are dovetails the strongest of all joints?
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 is the difference between 11mm and 3 8 dovetail?
The 3/8 Inch is measured across the bottom of the dovetail whereas the 11 mm is measured across the top of the dovetail. A 3/8 Inch dovetail is about 12.7 mm across the top. The measurements 3/8 and 11mm are not the same for this reason plus the angles are different.
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 is a 3 8 dovetail?

What is the strongest joint in carpentry?
MORTISE AND TENON JOINT Mortise and tenon joints are widely regarded as one of the strongest and most reliable woodworking joints. They involve creating a mortise, or a hole, in one piece of wood and a tenon on the end of the other piece, which fits into the mortise.
