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 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.

What is the correct angle for dovetails?

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.

What are the rules for dovetail joints?

The pins and tails only fit together from one direction. The single dovetail joint can either be a complete pin or a complete tale (Figure I). The multiple dovetail usually ends with a half pin on the corner; the half tail is usually avoided (Figure II). The tail board is a mirror of itself.

What is a dovetail design?

Dovetail joints are a sign of a true craftsman. Noted for their resilience to pull apart, these finger-like joints between two pieces of wood enable a tight, strong, and long lasting fit. Dovetail joints require zero mechanical fasteners, making them more attractive to the traditionalist.

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 most common 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.

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.

How do you mark a dovetail?

Mark out the two ‘half-pins’ at the edges on the first piece of wood. The ‘pins’ are the bits of wood between the tails so there are two half-pins; one each side. The general rule is that they measure half the thickness of timber plus around a mm, so the two dots on the shoulder line are 7mm in from each edge.

What are the important information of 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.

How do you identify a dovetail joint?

This joint type has two parts, called pins and tails. You can tell the difference between these two pieces because the tails are flared triangular shapes, while the pins are thinner. The tails, which look like those of a dove, are what give the dovetail joint its name.

What is the spacing for a dovetail joint?

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 are the dimensions of a dovetail slide?

What size dovetail chisels do you really need?

Sketch out the joint and get a chisel that fits into the pin slots. Or design the pins around your smallest chisel and get chopping. I use a 1/4″ and 1/2″ more than the rest of the sizes for all types of work (including dovetails) Erich. The next most used would be a 3/4″.

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 a 6 to 1 dovetail?

The left-hand photo shows the “ratio” method to layout the angle of your dovetails. (I used SketchUp to draw and show the angles.) A 1:6 ratio – that’s one unit horizontal with six matching units drawn vertical – lays out as a 9.5 degree angle.

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.

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 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.

How many mm is 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 size dividers for dovetails?

I recommend using two dividers for marking dovetails: one to mark the half pins and one to mark the full tails. I prefer the 4″dividers because I find them more comfortable to use than the larger sizes. In addition to dovetails you will find lots of uses for dividers.

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.

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.

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.

Do you need to clamp dovetails?

Well cut dovetails don’t need clamps, but it’s always nice to have clamps and cauls laid out just in case. I also like to have a piece of wood slightly thinner than my tails to use to tap the tails together to make sure they are fully seated. Before walking away, I check the case for square, then let the glue sit.
