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 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 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.
How do you calculate dovetail?
An industry standard in some spheres is to have half pins and full pins. so with our current scenario of 3″ we would have 2 x 3/16″ = 3/8″ plus the full pin of 3/8″ so 3/4″ pin accumulation. This then leaves 2 1/4″ for two tails so 1 1/8″ dovetails.
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 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 difference between a 6 to 1 and 8 to 1 dovetail jig?
Steeper angles like 1:6 give more strength to a joint in softwoods (in theory). The 1:8 angle gives a slimmer look, and because hardwoods are much stronger, it has plenty of hold. 1:8 is my favorite. Here’s how to set a sliding bevel or protractor to the correct dovetail angle (if you don’t have a jig or guide).
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 most common dovetail angle?
Percy Blandford, who has been writing about woodworking for a long time, writes in his new book, “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.
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.
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 rules for dovetail design?
As a rule of thumb the dovetail’s maximum width should occupy approximately 1/ 2 to 3/ 4 of the gasket’s width (leaving a 1/ 4 – 1/ 8 of gasket width on each side). For larger gasket widths, multiple dovetails can be made side-by- side, facing the same direction or inverted.
What is the geometry of dovetail?
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 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 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 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 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 an example of a dovetail?
The scheme is neatly dovetailed into the established system of private practice. Fraternity was dovetailed with obedience to administrative authority. His ‘reply’ – which begins before her speech has finished, the two passages dovetailing seamlessly – fits his line remarkably closely to her musical profile.
Why is it called dovetail?
Dovetail joints are made up of two parts called pins and tails. When a master craftsman wants to marry two boards together, they cut a series of pins on one board and matching tails on the other. They are trapezoidal in shape, resembling the tail feathers of a dove (hence the name dovetail).
What is stronger than a dovetail?
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.
Why are dovetail joints so strong?
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.
Which hand saw is best suited to making a dovetail joint?
You need a saw with rip teeth for dovetail work. This means the cutting edges of the teeth are approximately perpendicular to the length of the saw. Two saws that do the trick are a Japanese dozuki (top) and a Western backsaw.
