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 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 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 most common dovetail pitch?
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). 8:1 and higher ratios have a steeper angle that works well in hardwoods, since these woods aren’t as likely to compress and don’t require as extreme of wedge.
What is the best dovetail ratio?
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 3 8 and 11mm dovetail the same?
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 average size of a dovetail?
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 is the angle of dovetail in lathe?
Dovetails are typically either 45 degree or 60 degree. A dovetail cutter is an endmill whose form leaves behind a dovetail slot, such as often forms the ways of a machine tool.
What are the standards 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 average size of a dovetail?
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 is the standard dovetail ratio?
With regard to what to use, a common recommendation is 1:8 for hardwoods and 1:6 for softwoods. These recommendations are based on some arguments related to strength. However, people use a lot of different ratios depending on application and aesthetics.
How deep should a dovetail joint be?
Try to keep the depth of the dovetail groove between 1/3 and 1/2 the thickness of the part. For example, if the gable of a chest of drawers is 3/4″ thick, machine the dovetail groove between 1/4″ and 3/8″ deep. Any deeper and you will weaken the gable too much.
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 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 length for a dovetail saw?
Even if you’ll use your saw mostly for run of the mill drawer dovetails, the longer length will give much straighter cuts, and be much faster. It will also help you to see square. Go for around the 10″ (250mm) mark. Maybe a little longer if you work thicker stuff.
What is the best material for dovetail joints?
There are a lot of different types of wood out there but almost all woodworkers around the internet agree that the best wood to practice dovetails on is poplar. From my own experiences, I would have to agree. It has some of the best properties from both softwood and hardwood while not having big open grain.
What is the standard dovetail ratio?
With regard to what to use, a common recommendation is 1:8 for hardwoods and 1:6 for softwoods. These recommendations are based on some arguments related to strength. However, people use a lot of different ratios depending on application and aesthetics.
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.
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.
What degree is 1 8 dovetail?
A 1:8 ratio – one unit horizontal with eight matching units drawn vertical – is an angle of 7.1 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.
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.
Do dovetails need glue?
While it is true that tight-fitting dovetails on a drawer would not need any glue to keep them from being pulled apart in the direction that the drawer is used (i.e., pulled and pushed), it’s also true that dovetails use mechanical action to keep them together in only one direction.
What is the strongest joint in woodworking?
What is the strongest woodworking joint? For excellent stability, the mortise and tenon joint is a great choice. It’s a relatively simple joint, yet it holds well. Woodworkers have been using it for generations because of its strength, versatility and simple design.
When did they stop using dovetail joints?
By 1730, through dovetail joinery was abandoned in English furniture making in favor of the lapped construction. As furniture became more refined, furniture makers began to take pride in the construction of their drawers as well.
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.
