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 standard dovetail ratio?
Barron Dovetail Guides are available in 5 popular dovetail ratios (with their corresponding approximate angles): 1:4 (14°), 1:5 (11°), 1:6 (9.5°), 1:7 (8°), and 1:8 (7°), to accommodate whatever angle you find most visually appealing.
What is the difference between 1 6 and 1 8 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 ratio is a 14 degree dovetail?
Commonly accepted ratios are 1:8 for hardwoods and 1:6 for softer timber. This 14° marker equates to a ratio of 1:4. When used with thinner stock, the 14° angle results in a better looking joint.
What is the difference between 1 6 and 1 8 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 a 6 1 dovetail ratio?
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 a 1 8 dovetail ratio?

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.

Is dovetail the highest quality?
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.
How deep should a dovetail joint be?
Typically we use 1 ½” – 2” deep dovetails that are about 2” less deep than the joist, and 4” less deep than the girt – but that is just a starting point – the loads and reactions have to be calculated from there.
What are the traditional dovetail angles?
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!
Is 11mm dovetail the same as 3 8?
The 11 mm dovetail has a 60-degree angle, while the 3/8” dovetail has a 45-degree angle.
What size are standard dovetails?
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 are the measurements for a dovetail?
Your tails should be around 18mm > 35mm for fine work like drawers and 35mm > 55mm on larger work like a chest. Decide on your tail size remembering “One more tail than pin”. I have a distance between half pins of 330mm and I have chosen a pin size of 10mm. Set dividers to 1 tail +1 pin.
What is the difference between 11mm and 3 8 dovetail?
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 is the difference between 1 6 and 1 8 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.

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 11mm dovetail the same as 3 8?
The 11 mm dovetail has a 60-degree angle, while the 3/8” dovetail has a 45-degree angle.
What is the minimum thickness for a dovetail?
Minimum thickness is 1⁄4″[6mm]. Drawer side thickness ➂ does not affect bit selection. Note: B is the nominal working depth for half-blind dove- tails, not the maximum depth. B must not be varied, except for minor adjustments for joint fit.
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 half dovetail?
A half-blind dovetail enables the woodworker to hide the joint from the front end. The tails are housed in sockets in the ends of the board that is to be the front of the item so that their ends cannot be seen. Half-blind dovetails are commonly used to fasten drawer fronts to drawer sides.
What size router for dovetails?
Using a larger router will help, as the additional mass will help cut down on chatter. Try a Porter Cable router, and try both common sizes. The 1-1/2 hp is pretty easy to handle, and is a fine hand tool. The larger 3 hp unit will add mass and power, and maybe a variable speed.
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.

Methods. 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 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.
