Lower (7° to 9°) angles are often advised for joining hardwoods, while higher angles (10° to 14°) are recommended for softwoods and even higher angles (14° to 18°) for half-blind dovetails.
What ratio is a 14 degree dovetail?
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 are the typical angles of dovetail markers?
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.
What angle is 6 to 1 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 the strongest dovetail?
There are basically three types: through, or full, dovetails are used to join carcases, blanket chests, and small boxes. These are regarded as the strongest and most beautiful. Half-blind dovetails are commonly used to join drawer sides to drawer fronts and occasionally are employed on the construction of carcases.
What are the typical angles of dovetail markers?
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.
What is the common dovetail ratio?
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?
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 size dovetail should I use?
For drawers, boxes or trays 2″ or less I generally like a single dovetail. For 3″ to 3 1/2″ and less two dovetails, for 4″ three dovetails, for 5″ to 6″ four dovetails and for 6″ four or possibly five.
What is the most popular dovetail?
The through dovetail joint is the most popular dovetail joint because it is strong, attractive, and versatile. It is commonly used in furniture-making, cabinetry, and woodworking. The through dovetail joint is a traditional woodworking joint characterized by the interlocking triangular shape it creates.
What are the rules for dovetail joints?
The general rule is that they measure half the thickness of timber plus around 1 mm along the shoulder line. So these two awl dots are 7 mm in from each edge. These two dots, which mark the corners of the half pins, are now converted into a 1:8 slope at each side.
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 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 degree of a 1 in 8 dovetail?
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.
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 the best tool for dovetail joints?
For making perfect fixed dovetail joints, many woodworkers turn to the Leigh Super 18-inch Dovetail Jig. Dovetails and half-blind dovetail joints can be made fast and effortlessly with this woodworking tool, and look like they’ve been professionally made.
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 measurements for a dovetail?
Fine work the pins 4mm > 6mm, larger work 7mm > 12mm. To have a desirable appearance the pins smaller than the tails. 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”.
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 formula for the angle of the internal dovetail?
Explanation: Formula for finding the angle of an internal dovetail is Tan A = (l2-l1/2) / h where l1 and l2 are the distance across the pins and h is the height of slip gauges. Thus by knowing these three parameters, angle A can be calculated.
What are the typical angles of dovetail markers?
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.
How tight should dovetails be?
If you can use your fist as a hammer to nudge them together, they’re just right. By the way, when you realize they will fit nice and snug, (hopefully by the time they are less than half way down) take them apart and don’t put them together again until you glue them.
How thick should a dovetail jig be?
Dovetail Jig rave about the user-friendly features. The jig’s patented alignment lines and router bit-depth stop simplify set up and get you up and running in no time. This versatile jig accepts stock from 1/4 to 1-1/8 inch in thickness and up to 12 inches in width.
What size is a standard dovetail rail?
Should you glue dovetail joints?
Michael Dresdner: The only areas that require glue on dovetails are the diagonal faces. All the diagonal faces are long grain, all the square faces are end grain, and all the flat faces abut end grain. Therefore, you need only apply glue to the diagonal faces on the tails or pins, or both.
