Dovetail joints are one of the strongest corner joints used in woodworking. Why? The strength of
any wood joint depends on the amount of open surface area of the two pieces being joined. The more
glued surface area, the stronger the joint.
(also called a finger joint) is strong, the dovetail has it beat hands down.
This article explains wood joinery with a dovetail joint.
How the Dovetail Joint Maximizes End Grain for Strength
The name dovetail derives from the shape of the mating surfaces. On the socket piece of wood,
tail-shaped sockets are cut out. The narrow pieces of wood remaining between sockets are called pins.
The tail piece of wood is cut in the opposite fashion; the tails are left while small sockets
corresponding to the pins are removed.
On either piece, the joint at the top or bottom, once the joint is assembled, is called the shoulder.
So, tails mate with sockets and pins mate between tails. Once glued up, the incredible strength of
the dovetail joint makes it a favorite for drawer construction.
It also explains its popularity in antique furniture. Glue used in those days (hide glue) was not
as strong as the ones today, such as Gorilla Glue or Titebond III.
How are Dovetail Joints cut?
There are three basic methods to cutting dovetail joints. The most precise method is with a jig.
Cable Porter defined that market early although many innovators have come up with
their own designs. In fact, Rockler dovetail jigs are about the best on the market today.
are also popular.
Cutting dovetail joints using a router and a dovetail template is also very precise. This method is
useful in a heavy production environment because it allows the socket piece and the tail piece to be cut
at the same time.
But any cabinet maker or DIY carpenter worth his salt will be quick to point out that the only
true bragging rights are hard won by hand-cut dovetail joints! This is done by precise layout and
careful cutting using a dovetail saw, coping saw, and a chisel and mallet.

Tools for Hand-Cutting a Dovetail Joint
- Tape measure
- Marking gauge
- T bevel
- Dovetail saw
- Coping saw
- Chisel or mallet
- Coping saw
- Try (or tri) square
- Work bench-mounted wood vice
Layout and Hand-Cutting a Dovetail Joint
- Mark the depth of the cut on the tail piece and the socket piece. Use a marking gauge to
scribe around all four sides of the tail piece. The distance from the end of the board to the
scribe mark is the thickness of the board.
- Lay out the tails using a T bevel set at the chosen angle. Make them equal in size. Allow
for cutting both ends for the shoulders and a minimum of one quarter inch between tails to
- Clamp the tail piece in a vice. Use a dovetail saw to cut the shoulders and between tails.
A coping saw is handy to get into the tight corners and cut the piece out.
- Use a hammer and chisel to finish the job.
- Now, put the socket piece vertically in the vice. Hold the tail piece horizontally at the
end to allow tracing out the areas between the tails that were just cut.
- Use a try square and pencil to continue the lines on the socket piece.
- Cut the sockets out.
- Dry fit the dovetail joint and make any adjustments.
- Glue it up, clamp it (usually in a 45 degree clamp such as a picture clamp), and let the
- A final sanding and its done!
