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 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 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.
Do you clamp dovetail joints?
No need for clamps if you dovetails are tight. I will clamp a board that may have bow a little. Don’t sweat the glue bond, a good dovetail doesn’t depend on glue for much of it’s strength. I bang them together with a rubber mallet.
What makes a dovetail joint strong?
Methods. The dovetail joint is very strong because of the way the ‘tails’ and ‘pins’ are shaped. This makes it difficult to pull the joint apart and virtually impossible when glue is added.
Is a dovetail joint strong or weak?
Dovetail joints are known for their inherent strength and resistance to being pulled apart (tensile strength).
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.
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.
What is the best angle for a dovetail joint?
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.
Are dovetail joints worth it?
Dovetail drawers are known for their durability. The joint’s design provides exceptional resistance to the stresses of heavy items, making them ideal for storing dishes, pots, and pans. The construction of dovetail drawers ensures that they will not come apart easily, even with frequent use.
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 strongest joint in carpentry?
MORTISE AND TENON JOINT Mortise and tenon joints are widely regarded as one of the strongest and most reliable woodworking joints. They involve creating a mortise, or a hole, in one piece of wood and a tenon on the end of the other piece, which fits into the mortise.
What is an alternative to a dovetail joint?
Finger joints are an effective and striking alternative to traditional dovetail joinery.
What’s the strongest corner joint?
Mortise and tenon joints have stood the test of time for their remarkable strength. This traditional joint involves a projecting piece of wood, called a tenon, securely fitting into a corresponding cavity, a mortise. It can be reinforced with glue or wedges for stability for a stronger hold.
What is the standard angle for a dovetail?
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.
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.
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 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 tight should dovetails be?
If you can use your fist as a hammer to nudge them together, they’re just right. By the way, when you realize they will fit nice and snug, (hopefully by the time they are less than half way down) take them apart and don’t put them together again until you glue them.
Is dovetail the highest quality?
Dovetail joinery is a benchmark of high-quality construction because these fasteners are all potential weak points that can degrade or break-down over time.
What is the easiest joint for woodworking?
A butt joint is the easiest of all simple wood joints, but also is the weakest. The cut end of one board butts up against the edge of another piece at a right angle.
What is one of the strongest woodworking joints made of three sided?
The dado joint is one of the strongest woodworking. joints you can make. A dado joint is made from a three- sided channel cut across the grain of one work piece.
Can you make dovetail joints with plywood?
A wide variety of methods can be used to make dovetail plywood drawer boxes. They are generally considered by the woodworking industry as time-consuming and difficult to make. The dovetails can be cut by hand with a dovetailing saw and chisel or you can use a dovetail jig and router.
Are dovetails hard to make?
It’s true that dovetail is hard to make, but all it takes is a couple of stabs at the joint and even a novice will be happy about the results.
What is an English dovetail joint?
A dovetail joint is a locking joint. The English dovetail construction tends to allow for the largest possible drawer storage capacity. French dovetail construction is used for more elaborate features such a curved, bowed design.
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.
