The narrower center tail adds visual interest and lends to the hand cut look of the joint. (Here I mean the mechanical or interlocking strength of the joint. That's vital if you want your joint to turn out. After cutting the pieces to size and truing them up, it is very helpful to mark the inside and outside faces of each board to avoid confusion. The jig also has a centerline marked on it with holes cut out that make it easy to align the jig with the log. If you want a dovetail joint to look hand-cut, you must lay it out properly. If neither the inside or outside dimensions of the box is absolutely critical, then the boards can be cut to length without much concern if the actual final dimensions vary a little.

pins or tails. (Half pins are not necessarily one-half the width of any other pin, it's just that they're cut on only one side). The pins are cut on the drawer's front and back, and the tails are cut on the sides.
Today we'll address a skill you'll need, no matter which of the jigs you use. (The edges can be smoothed on a jointer or with a hand plane, but I usually wait until after the dovetails are cut for the final smoothing.). To illustrate, refer to the drawing at right. strength of the joint may not be the primary consideration. 1 simply w rite in large letters "IN"' and "OUT' near the end of each board where the dovetail is to be cut. The pins are on the legs to keep them from splaying out, which wrorks out nicely because the tails must be on the top to support the wreight.
As a general rule I use a minimum 1:4 ratio for the relationship between the pins (1) and tails (4). Otherwise choose and angle between 7 and 15 degrees. Then I can transfer their shapes to the end of my pins board. Use a square to carry those lines down both faces of the workpiece, stopping at the thickness lines you drew across the face earlier. The basic procedure for marking the base lines is to use the thickness of the board for the tails (in this case, the sides) to set the marking gauge. Calculate Dimensions, Angles, Log Gap and Overlap to Create Full Scale Printable Templates for Log Cabin Half Dovetails - Metric. Make sure you mark them accurately; the success of your joint depends upon it! This has to do with the size and placement of the tails. The direction of strength is toward the pins. Also, make sure the thickness (particularly at the ends of the boards) is equal from one edge to the other. Be sure not to go past your depth line, insert the saw into the step down and alongside the knifewall to help guide your saw.
Visit one of our sponsor's websites today! One way to lay out the cuts for a dovetail is to use a ruler to divide the board for the pins into equal spaces. And in the June issue was a dovetail jig for the table saw. Once again this a matter of personal (visual) preference. Please support those who support us by visiting their websites and having a quick look around-, Blue Collar Woodworking, Stumpy Nubs, Stumpy Nubs Woodworking Journal and Mustache Mike are all trademarks of, Midwestern Trading Company, Michigan, USA - Copyright 2011-2018 MWTco, January issue of Stumpy Nubs Woodworking Journal, any of the easy to make jigs on our website, that's what the jig I like to use requires, separate video about cutting half-blind dovetails. Just be sure your pencil is nice and sharp, so your lines are accurate. All of this can be done by eye.
But the first step (indeed.
Then the pins and the spaces between the pins (which will be the tails) are laid out at equal widths. All four corners are joined with through dovetails. Create a step down using a chisel on the waste side of the line (see picture for detail), then use a dovetail saw to cut across the grain. Traditionally shallower angles were used for soft woods, and steeper angles for hard woods. The base line also dictates the amount of work you must do during the final cleaning up stage. Once you've collected the tools to do the job, it's time to start laying out the cuts.
Before you can cut the tails half of the joint, you first must transfer the shapes of your pins to your tails board. But this time I am putting one tail in the center, which I indicate with a pair of marks, about 1/8" apart on each side of where I want that center tail. Stand your tails board on its end, and butt your pins board against it. After planing the sides a little bit, the plane gets down to the end grain on the pins, making it nice and smooth. ie: 3.75 = 3 3 4 or 3 3/4 Select appropriate angle and overlap to obtain desired log gap. However, I mark and cut the pins first for three reasons. The base lines determine the final measurements (the final length) of the boards you're joining together. Just to keep you on your toes, when viewed from the ends of the boards the pins look like tails, and the tails look like pins.
A dovetail joint is made up of two halves. In other words, the boards should be flat and smooth — to the point that all they need is a little finish sanding.
Please support those who make what we do possible. Half blind dovetails (which are used mainly in drawer construction) will be covered in the next issue. This time, we're laying out the tails first, rather than the pins, because that's what the jig I like to use requires. This base line is actually the bottom of the cut on both pieces, and in effect dictates the final dimensions of the box. Place the blade of your bevel gauge on the line next to half-pin on the left corner of the workpiece, and strike a line, angling to the right. Now, let's move on to the more challenging half-blind dovetail joint layout. . In the January issue of Stumpy Nubs Woodworking Journal, I showed you a cool router table sled for creating flawless dovetails that look hand-cut. It's easy to get your pencil between them to trace their shapes onto the tails board than it is to do it the other way around.
At this point I'm supposed to launch into a discussion about pins and tails, and angles, and such. If you are using a jig with a fixed fence angle, like the router table dovetail jig, or the table saw sled dovetail jig, set a bevel gauge to the angle of that fence. Second, whichever half is marked first (the pins in my case) is used to mark the lines for the second cuts (the tails). To set the sliding bevel at the proper angle, I use a small piece of plywood. Some people like to cut the pins half first, others like to start with the tails.
That's it for laying out traditional through-dovetails. But it is satisfying work .
The result is that the pins will stick out just a hair beyond the face of the sides when the joint is complete. (I prefer the band saw.) You have a “pins” side and a “tails” side, which must cut separately. Also you'll be removing the shoulder (scratch) line at the same time. Let's say, for example, that you're going to build a drawer. If you are cutting half-blind dovetails, especially with the clamp-on jig we featured in the January 2018 issue of Stumpy Nubs Woodworking Journal, you must do things slightly differently. If this joint were on a drawer, for example, the pins would be cut on the drawer front where the mechanical strength of the joint holds the drawer together as it's pulled open. Without getting bogged down in too much detail, you have three choices. Next, clamp the pins board in the vise with the P facing toward you, and use a pencil to place marks on the end-grain about 1/4" from each of the two edges.
In some cases both direction of strength and direction of pressure must be considered — as with the coffee table in this issue. blocklayer.com Directory ? Inch or Metric. Now the question arises: Which board gets the pins, and which board gets the tails? Machine cut dovetails are easy to identify because the pins are typically at least as wide as the 1/4" shank of the router bit, and they are usually evenly spaced and sized. Which do you cut first, the pins or the tails?
The boards are true, the ends are cut off square. They must then be cut, filed or planed down flush. Dovetails are normally used to join four boards at right angles to form a box. This just takes a little getting used to. This will give you the offset needed to make it a half-blind dovetail. The last consideration is the angle used for layout. What's the first step in laying out a dovetail? Believe me, it happens!
In the March issue we featured another clever jig that clamps onto the end of a workpiece for cutting dovetails with a hand held router. For, pins equal width, tails increase at center. As always, I like to cut the tails half of any dovetail joint on a band saw. This will ensure things don't get goofed up during the layout phase.
(Here I mean the mechanical or interlocking strength of the joint.
Just place it against the ends of your tails and flush it up with the face of the pins board. First, I think the pins are easier to cut and I like to get started with the easy part. Next, flip the gauge and work your way back in the other direction, drawing lines from the left side of each pin, angling to the left. Help. You may notice that I didn't divide the joint evenly.
