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″.
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″.
What is the best ratio for dovetails?
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.
Can you use a dovetail jig on 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.
What are the common dovetail sizes?
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.
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″.
Are 3 8 and 11mm dovetail the same?
However, that is not the only difference between the two dovetails. They also have different groove angles as shown below. The 11 mm dovetail has a 60-degree angle, while the 3/8” dovetail has a 45-degree angle.
What are the rules for a dovetail joint?
The general rule is that they measure half the thickness of timber plus around 1 mm along the shoulder line. So these two awl dots are 7 mm in from each edge. These two dots, which mark the corners of the half pins, are now converted into a 1:8 slope at each side.
Are dovetails the strongest of all joints?
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 dovetail the strongest joint?
Strength. 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 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.
Is a dovetail jig worth it?
Why Using A Dovetail Jig Is Beneficial For Woodworkers? With a dovetail jig, you can make accurate and precise dovetail joints with no irregular or weird cuts. You can also create different angles on a sloping wood piece edge with the jig, which is impossible with a hand cutter.
Can I make my own dovetail jig?
All you need is some standard, off-the-shelf hardware, 5 board feet of hardwood , and a piece of hardboard to make your own “comb” template. However, as I got into the project further I found some improvements I could make over manufactured dovetail jigs along the way.
Is dovetail 11mm?
The standard 22 tip-off dovetail in the US is 3/8″ at the bottom and up to 1/2″ at the top. The European 11mm dovetail is typically 11mm at the top and perhaps 8mm at the bottom. The 11mm dovetail typically has a 60 degree angle from the bottom inside corner to the top where the 3/8″ is typically 45 degrees.
What is the spacing for dovetail jigs?
Most templates are designed to cut 1⁄2″-wide dovetails spaced 7⁄8″ apart. Other jigs space the dovetails 1″ or 1 1⁄8″ apart. (We use the 7⁄8″ spacing for Woodsmith projects.)
What size router for dovetail jig?
Using a larger router will help, as the additional mass will help cut down on chatter. Try a Porter Cable router, and try both common sizes. The 1-1/2 hp is pretty easy to handle, and is a fine hand tool. The larger 3 hp unit will add mass and power, and maybe a variable speed.
What is a standard dovetail?
A series of pins cut to extend from the end of one board interlock with a series of ‘tails’ cut into the end of another board. The pins and tails have a trapezoidal shape. Once glued, a wooden dovetail joint requires no mechanical fasteners.
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 ratio is a 14 degree dovetail?
There is no hard and fast rule when it comes to dovetail angles. Commonly accepted ratios are 1:8 for hardwoods and 1:6 for softer timber. This 14° marker equates to a ratio of 1:4.
Are all dovetail bits 14 degrees?
You’ll need a jig to make most dovetail joints, as well as a guide Bushing for your router. Check the instructions with your Dovetail jig to select a bit with the appropriate angle, which will usually be somewhere between 7 and 14 degrees.
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″.
What is the best dovetail angle?
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 angle 1 to 8 dovetail?
A 1:8 ratio – one unit horizontal with eight matching units drawn vertical – is an angle of 7.1 degrees.
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.
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.
