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 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 typical angle of a dovetail metal?
Angles used on dovetails On large industrial scale machines the angle is usually 45º. For smaller dovetails the usual angle is 60º. Any less than this, i.e. 60° on a small machine, complicates the design of the adjustment mechanism. The angle produced is set by the dovetail cutter used.
What is angle 1 to 8 dovetail?
A 1:8 ratio – one unit horizontal with eight matching units drawn vertical – is an angle of 7.1 degrees.
What is the slope of a dovetail joint?
The angles marked for this dovetail joint are 1:8 which is suitable for hardwoods. An angle of 1:5 or 1:6 is better for softwoods. All marking out methods are essentially the same and most woodworkers will find their own variation on the theme.
What is the standard dovetail ratio?
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. When used with thinner stock, the 14° angle results in a better looking joint.
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 are the rules for dovetail?
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.
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 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 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.
What are the 2 types of dovetail joints?
Types of Dovetail Joints Half-Blind dovetails: In these, the pins and tails are hidden. Half-blind dovetails are only revealed when moved, opened or seen from a certain angle, like behind a drawer face. In a through dovetail, both the dovetails and pins are visible.
What is a French dovetail joint?
French or sliding dovetail joints consist of only a single tail and pin with the tail being slid into a long groove on the connecting piece. The tail is tapered so that it locks in securely just like any other dovetail joint.
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.
How big 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.
Is a dovetail joint strong or weak?
Dovetail joints are very strong by design and they also offer an attractive finish that is a true sign of craftsmanship. Professionally cut and glued dovetail joints are virtually impossible to separate.
What angle is a dovetail cutter?
A dovetail joint is most commonly used in wood working but also in metal working as a way of creating a joint which is extremely strong. Dovetails are typically either 45 degree or 60 degree.
What is the most popular dovetail joint?
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 is the main wood joinery method dovetail?
Sliding dovetail joints function by joining two boards at a right angle, with the side of one wooden board cut into a tail. The other wooden board needs to have a socket cut into it away from the edge of the board. The two pieces interlock when you slide the tail into the socket.
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 a 11mm dovetail rail?
Description. This 11mm dovetail rail attaches to the receiver of Savage MKII rifles to allow the use of Gehmann, Anschutz, or other rear sight options. This is the same rail included with our complete biathlon sight set for the Savage rifles.
How big should a dovetail be?
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.
Are dovetail joints worth it?
Making sure that you pick a drawer joint that can withstand this type of wear and tear is crucial to the longevity of your kitchen cabinets. Dovetail joints are considered one of the strongest joints used in kitchen cabinetry construction and are the best solution for a kitchen cabinet drawer box.
