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 best angle for a dovetail?
Although softwoods are more compressible than hardwoods, you needn’t change the dovetail angle to add strength to the joint. Any angle between 7° and 15° will work, regardless of the wood. But stay within that range.
What are the typical angles of dovetail markers?
My go-to angle for through dovetails in most hardwoods is 7:1 (8.1°), such as for a carcase or box in cherry, maple, or walnut with stock thickness of 9/16″-13/16″. It has enough angle to form a strong mechanical lock but not too much to produce fragile tail corners or overly fussy fitting.
At what angle to the horizontal is a dovetail cut?
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.
Are all dovetail bits 14 degrees?
You’ll need a jig to make most dovetail joints, as well as a guide Bushing for your router. Check the instructions with your Dovetail jig to select a bit with the appropriate angle, which will usually be somewhere between 7 and 14 degrees.
Is 11mm dovetail the same as 3 8?
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 angle 1 to 8 dovetail?

What is the most popular dovetail?
1) Through Dovetail Also known as the plain dovetail, this is the most common and basic type of dovetail joint. Through interlocking tails and pins, this joint showcases consistent angles, revealing the wood’s end grains on external surfaces.
Which part of a dovetail do you cut first?
Cutting the dovetail pins first makes sense. It’s easier to hold the pin board in place to mark the tails than it is to hold the tail board against the end of what will be the pin board. Also, the walls of the pins provide a good surface for the awl as you mark the tails.1 Feb 1996

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.
How big should a dovetail joint be?

What is an English dovetail joint?
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.
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?
It depends on the application. 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.
How hard is it to make a dovetail joint?
It’s true that dovetail is hard to make, but all it takes is a couple of stabs at the joint and even a novice will be happy about the results.
What tool is commonly used to cut dovetails?
You can do this with either a dovetail or crosscut saw. Flip the board sideways, set your saw edge in the marking gauge line, and cut down to the first tail at 90°. You can use the 90° side of my dovetail jig as a guide. If you don’t have one, make a knife wall to help guide your saw.
When did they stop using dovetail?
According to oldcopper.org, coppersmiths kept on dovetailing the seams until about 1900, after which better joinery technology made the time-consuming dovetail process obsolete. This means that a dovetailed pot or pan could have been hand-cut or machine-cut.
