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 standard size of a dovetail?
11 mm and 3/8” dovetails are the two most common types of dovetails that you can find on rifles. The 11 mm dovetail represents a standard in Europe, while the 3/8” is a standard in the USA.
Why use dovetail groove?
Dovetail grooves are used to hold the O-ring in place during installation or maintenance. This groove design is relatively uncommon as it is expensive to machine and should not be used unless absolutely required.
Why use dovetail groove?

What are the rules for dovetails?
What are the proportions for a dovetail joint?
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 are the three types of dovetail joints?
The following are the different types of dovetail joints: Through dovetail. Half-blind dovetail. Secret mitered dovetail.
Is 11mm and 3 8 dovetail the same?
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 are the dimensions of a dovetail slide?
What is the most common 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 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.
Why use dovetail groove?
Dovetail grooves are used to hold the O-ring in place during installation or maintenance. This groove design is relatively uncommon as it is expensive to machine and should not be used unless absolutely required.
What is the angle ratio for dovetails?
You don’t want your angle so steep as to create so much short grain that the tails break during assembly; too straight of an angle and you lose the mechanical advantage dovetails offer. Over time you will probably notice an affinity to a certain ratio; personally, I like 1:7 best.
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 a 1 to 6 ratio 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 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 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 are the important facts about dovetail joints?
Dovetail joints are known for their inherent strength and resistance to being pulled apart (tensile strength). A dovetail joint has a series of pins and tails in a trapezoidal shape and once glued a dovetail joint has no need for mechanical fasteners.
What is an English dovetail joint?
English Dovetail / Through Dovetail The craftsperson usually orients the tails and pins in this joint horizontally, although this isn’t a cardinal rule. It is sometimes called a through dovetail because both the pins and tails go all the way through each-other.
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 most common dovetail angle?
Answer from the experts: Clearly, there’s no shortage of advice about the “best” dovetail angle: Some woodworkers recommend using 12° for “coarse work” and 7° to 10° for decorative joints.
What is the difference between a half blind dovetail and a through dovetail?
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 the difference between English dovetail and French dovetail?
English dovetails are the most common. They have interlocking joints and allow the most amount of space – usually several more inches of room than you would get with French dovetails. This is because the dovetail groove cannot be put all the way at the edge of a drawer with French dovetails.
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.
When did they stop using dovetail?
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 ideal dovetail angle?
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.
