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 dovetail ratio is best?
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 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 the ratio of a dovetail pitch?
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. As long as it looks good, and assembles without breaking, its a good joint.
What is the ratio of pin to tail for dovetail joints?
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).

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 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 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 size dovetail should I use?
We recommend dovetail width should not be less than 75% of the width of the stock. This is a general ratio, not a rule. If in doubt, stick to 75%. Dovetail width should be narrow enough to support the part after material is removed.
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 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 angle should a dovetail joint be?
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. 5. They are called ‘dovetails’ because they are shaped like the tail feathers of a dove!
What is stronger dovetail or finger joint?
Although the finger joint is not mechanically interlocking like a dovetail, the joint is amazingly strong. Today’s modern adhesives and the large glue surface make the finger joint equally as strong as the dovetail throughout the life of the adhesive.
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.
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 size dovetail should I use?
We recommend dovetail width should not be less than 75% of the width of the stock. This is a general ratio, not a rule. If in doubt, stick to 75%. Dovetail width should be narrow enough to support the part after material is removed.
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.
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.

Are weaver and dovetail the same?
Also called a “tip off” mount, the dovetail rail allows the shooter to easily remove and replace mounted optics. Although dovetail rails come in a variety of sizes, the most common are 11mm and 3⁄8 inch (9.5 mm). Developed by William Ralph Weaver, the Weaver rail was created in an attempt to standardize scope mounts.
