A 1:6 ratio – that’s one unit horizontal with six matching units drawn vertical – lays out as a 9.5 degree angle.
What is the ratio of a dovetail to an angle?
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 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 the ratio for 14 degree dovetail?
This 14° marker equates to a ratio of 1:4. When used with thinner stock, the 14° angle results in a better looking joint. This different angle also gives you a slightly stronger dovetail interlock on the thinner material.
What is the slope of a dovetail joint?
There are different types of dovetail joints. The angle of slope varies according to the wood used, purpose of joint and type of work. Typically the slope is 1:6 for softwoods, and a shallower 1:8 slope for hardwoods. Often a slope of 1:7 is used as a compromise.
What is the angle of a 11mm dovetail?
The 11 mm dovetail has a 60-degree angle, while the 3/8” dovetail has a 45-degree angle.
What are the measurements for a dovetail?
DoveTail Description: 60 degree dove tail, approximately 1-inch tall and 4-inches across the tail corners and uses a 1/4-inch thick gib plate on one side. Guessing dimensions will be: depth(s), pin diameter, and dimension across/between pins.
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.
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 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 dovetail ratio is best?
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 are the angles in the ratio 5 3 10?
Answer. thus, the angles are 100, 30, 50 degree respectively.
What is a standard dovetail?
Standard dovetail joints have evenly spaced cut pins and tails, traditional dovetails have wide-cut pins and smaller tails. Standard cut pins and tails offer more strength in the drawer, traditional is not quite so strong but are often specified because of their traditional finish.
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″.
Is dovetail the strongest joint?
A dovetail joint is often considered one of the strongest and most durable woodworking joints due to its interlocking design. The trapezoidal shape of the dovetail and its wedge-like construction make it resistant to being pulled apart.
What is angle 1 to 8 dovetail?
A 1:8 ratio – one unit horizontal with eight matching units drawn vertical – is an angle of 7.1 degrees.
At what angle to the horizontal is a dovetail cut?
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 the angle of the internal dovetail?
Explanation: Formula for finding the angle of an internal dovetail is Tan A = (l2-l1/2) / h where l1 and l2 are the distance across the pins and h is the height of slip gauges. Thus by knowing these three parameters, angle A can be calculated.

What is the angle of a 1 8 dovetail in degrees?
It would be extremely difficult to be able to pick these differences up in your dovetails on a piece of furniture by eye. So in closing your 1:4 Saddle-Tail is for all practical purposes 14 degrees, the 1:6 is close to 10 degrees and the 1:8 is about 7 degrees.
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 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?
The interlocking design of the dovetail creates a strong bond that can withstand a lot of stress. On the other hand, a box joint, also known as a finger joint, is strong in terms of sheer surface area and glue surface, making it suitable for joining the corners of a box or a drawer.
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.
What is an English dovetail joint?
A dovetail joint is a locking joint. The English dovetail construction tends to allow for the largest possible drawer storage capacity. French dovetail construction is used for more elaborate features such a curved, bowed design.
