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 ratio is a 14 degree dovetail?
There is no hard and fast rule when it comes to dovetail angles. Commonly accepted ratios are 1:8 for hardwoods and 1:6 for softer timber. This 14° marker equates to a ratio of 1:4.
What is 1 to 6 ratio dovetail?
A 1:6 ratio – that’s one unit horizontal with six matching units drawn vertical – lays out as a 9.5 degree angle. A 1:8 ratio – one unit horizontal with eight matching units drawn vertical – is an angle of 7.1 degrees.
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.

Are 3 8 and 11mm dovetail the same?
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 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 standard dovetail?
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.
What is a standard dovetail angle?
4. The angle of a dovetail joint should be between 7 and 15 degrees: too broad and the joint won’t be strong enough, too skinny, and the pin can snap. So the angle of the dovetail mainly depends on the use and wear the joint will get. Diagram showing dovetail angles vs strength from Fine Woodworking.
What are common dovetail sizes?
What is the ratio of tail to pin in a dovetail joint?
The line between that end point and starting point will be the angle of your tail and pin sides. 6:1 (9.5°) and 8:1 (7.1°) dovetail ratios are the most common (though you’ll often see 4:1 and 10:1 as well).
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.
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 English dovetail?
What is the ratio of tail to pin in a dovetail joint?
The line between that end point and starting point will be the angle of your tail and pin sides. 6:1 (9.5°) and 8:1 (7.1°) dovetail ratios are the most common (though you’ll often see 4:1 and 10:1 as well).
What are the rules for dovetails?
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 makes a dovetail joint so strong?
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 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 1 to 6 ratio dovetail?
A 1:6 ratio – that’s one unit horizontal with six matching units drawn vertical – lays out as a 9.5 degree angle. A 1:8 ratio – one unit horizontal with eight matching units drawn vertical – is an angle of 7.1 degrees.
What rifles have 11mm dovetail?
Is dovetail the strongest joint?
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.
Is dovetail the highest quality?
Without a doubt, dovetail joints are revered as one of the strongest woodworking joints. The strength lies in the precise shaping of the tails and pins. When these elements fit snugly together and are bonded with glue, the resulting joint becomes nearly impossible to pull apart.
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.
