What is the spacing for a dovetail joint?

Step 6: Spacing 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”.

How far apart should dovetails be?

There should be roughly one dovetail each 25mm or so across the width. There’s no hard and fast rule so it’s up to the woodworker to use his or her judgement to decide how many are needed.

How do you calculate the spacing of a dovetail?

What are the measurements for a dovetail joint?

Dovetail Dado Wood Joints have joint widths of 2/3 and joint depths of 1/2. Wood joints are typically used in wood members with widths between 1.5”-3.5” (3.8-8.9 cm) and depths between of . 75”-3.5” (1.9-8.9 cm).

Should dovetail joints be glued?

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 best angle for a dovetail?

Although softwoods are more compressible than hardwoods, you needn’t change the dovetail angle to add strength to the joint. Any angle between 7° and 15° will work, regardless of the wood. But stay within that range.

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 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.

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.

Is dovetail joint permanent?

The strongest and most permanent right-angled joints made in wood are the ‘dove-tail’ joints, as illustrated below. The so-called tails and pins fit together to form a secure joint.

Are 3 8 and 11mm 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.

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 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 minimum thickness for a dovetail?

In my own work I aim for a minimum size of 1/4″ and mostly 3/8″. Now that doesn’t mean I won’t go down to less or up too.

What is the best angle for dovetails?

Are dovetails the strongest of all joints?

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. Because of the preciseness of each piece, this joint is held into place without the need for extra reinforcement.

What is stronger dovetail or finger joint?

Although the finger joint is not mechanically interlocking like a dovetail, the joint is amazingly strong. Today’s modern adhesives and the large glue surface make the finger joint equally as strong as the dovetail throughout the life of the adhesive.

Do you need to clamp dovetails?

I always make sure the side beieing assembled is down on the surface of the table to avoid splitting. In other words I’m hammering the pin board into the tail board not hammering the tail board onto the pin board. No need for clamps if you dovetails are tight. I will clamp a board that may have bow a little.

What is the 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 difficult is a dovetail joint?

Hand-cutting a dovetail joint is kind of a woodworking high-wire act; one slip of the saw or chisel and the joint either won’t fit together or will look sloppy. It takes a lot of time to master the ability to cut dovetails quickly and well (by hand or machine), without a lot of fussing around.

Is a dovetail joint strong or weak?

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. Because of the preciseness of each piece, this joint is held into place without the need for extra reinforcement.

What is the angle of a dovetail slide?

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 the weakest joint in carpentry?

A butt joint uses a simple technique whereby two pieces of material are joined together at their ends, without any special shaping or cutting. Although it is simple, the butt joint is also the weakest of the wood joinery types.

How can I improve my dovetails?

Yes, the three things I did that truly improved my dovetails are cutting a clean, deep shoulder line on both the tail and pin boards, getting serious about transferring the tails to the pin board accurately, and understanding how those layout lines inform paring when fitting the pins to the tails.

When did they stop using dovetail joints?

Hand-cut dovetailing was the default until 1860 when uniform machine-cut joints were introduced. But fine cabinetmakers persisted in fitting their joints by hand until the early 1900s, and cabinetmakers in Europe cut dovetails by hand well into the 1930s.

What is stronger than a dovetail joint?

Frid wrote that finger (or box) joints are stronger than through dovetails because the fingers offer much more glue surface.
