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 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.
What is the ratio of tail to pin in a dovetail joint?
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.

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.
How do you size a dovetail?
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 1 to 6 ratio in degrees?
A 1:6 ratio – that’s one unit horizontal with six matching units drawn vertical – lays out as a 9.5 degree angle.
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 are common dovetail sizes?
Dovetails come in several different types and sizes depending on manufacturer, but the most common are the 11 mm and 3⁄8 inch (9.5 mm). Some other less known, but currently commercially available dovetail mounts, are 12, 13, 13.5, 14, 14.5, 16, 16.5, 17 and 19 mm.
What is the difference between a pin and a tail dovetail?
There are two parts to a dovetail joint, pins and tails. The tails look like the tail of a dove (hence the name), and the pins are on the opposite board and fit in between the tails to create a joint that is impossible to pull apart in at least one direction.
What are the ratios for dovetail angles?
For those of you unfamiliar with them, the angle at which dovetails are cut is usually referred to by ratio, for example, 1:7 or 1:6. To draw the angle, you layout a horizontal line with a vertical line intersecting it at 90 degrees.
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.
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.

Is dovetail the strongest joint?
It used to be. Now we have good adhesives— today’s glues are stronger than wood itself— this is no longer true. A box joint provides more glue surface than a dovetail and should be used if strength is your purpose. Dovetails are still used because they are pretty, though.
How do you measure dovetail pins?
The ‘pins’ are the bits of wood between the tails so there are two half-pins; one each side. The general rule is that they measure half the thickness of timber plus around a mm, so the two dots on the shoulder line are 7mm in from each edge.
What’s the difference between dovetail and Weaver?
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.
