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 shoulder line should be fractionally bigger (0.5mm) than the thickness of the wood to allow for a little overhang when the joint goes together. 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.
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).
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.
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.
Are dovetails the strongest joint?
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.
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.
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.
Are dovetail joints still used?
They are still used today by many experienced custom furniture makers. Dovetail joints are not only used to make a strong joint for drawer construction, but cabinet makers often use them to join the tops, bottoms and sides of cabinet cases, as was done on antique furniture.
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’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.
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?
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.
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.
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 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.
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.
How thick should dovetails be?
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″.
Is a half blind dovetail joint strong?
Joining drawer sides to drawer fronts using the half-blind joint leaves the front of the drawer without visible joinery while providing great interlocking strength opposing the stresses constantly applied to the drawer when opening and closing.
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 the most aesthetic wood joint?
Of all wood joinery methods, the through dovetail may be the most revered. A classic through dovetail is beautiful and very strong and adds a touch of class to any piece. There are a few methods for creating through dovetails, from hand cutting to machining with a jig.
