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 ratio of a dovetail to an angle?
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 degree is 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.
What ratio for dovetail hardwood?
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 angle of a 11mm dovetail?
The 11 mm dovetail has a 60-degree angle, while the 3/8” dovetail has a 45-degree angle.
Is 11mm and 3 8 dovetail the same?
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 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 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.
What is a standard dovetail?
Standard dovetail joints have evenly spaced cut pins and tails, traditional dovetails have wide-cut pins and smaller tails.
How thick should dovetails be?
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 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 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 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 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 typical angles of dovetail markers?
Dovetail angles are expressed in two ways: as ratios and degrees. 1:8 roughly translates to 70 and 1:6 translates roughly as 90. These days, we often hear that 90 is recommended for softwoods, while 70 should be used for hardwoods.
What is the ratio of a dovetail to an angle?
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.

Which angle is 11 15?
So, Angle between the hour and minute hand of a clock at 11:15 is 22.5∘ + 90∘ = 112.5∘
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 stronger dovetail or finger 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.
