Introduction: How to Dovetail

Picture of How to Dovetail

The through dovetail joint is strong and attractive. It's the traditional joint of choice for joining boards at right angles. Here is how I went about setting out and cutting my dovetails using hand tools and with some practice you can too. As always make sure you take all necessary safety precautions and follow all the safety instructions provided with your tools.

If you like the guide check out and sign up for my woodworking blog, i'm on youtube, facebook, twitter and pinterest too

Step 1: Terminology

Picture of Terminology

Just to keep things easy I have labelled the key areas of the through dovetail joint.

Step 2: Tools

Picture of Tools

These are the tools I used. Mallet, Bevel Edge Chisels, Marking Gauge, Cutting Gauge, Dovetail Saw, Dividers, Marking Knife, Hard Pencil, Dovetail Square (or adjustable bevel), Try Square, Ruler, Smoothing Plane, Coping Saw

Step 3: Face Side, Face Edge

Picture of Face Side, Face Edge

Make sure your material is cut to an accurate dead length, apply face side faced edge marks and reference the corners.

Step 4: Baseline

Picture of Baseline

Set your cutting gauge to create the base line. Set it to the exact thickness of the timber to be joined. In this case the timber is of equal thickness. If the thickness of the stock varies apply the thickness of the tail board to the pin board and pin board to the tail board. For best results use the timber to set your gauge. Don’t be too aggressive with the gauge. We just want to create a nice edge for a chisel to pare from later.

Step 5: Half Pins

Picture of Half Pins

Dovetail joints start with a half pin located on the outside of the joints. Typically on fine work this would be 6mm > 9mm on larger work like a tool chest 10mm > 18mm would be acceptable. Set your marking gauge to the half pin size of your choice and mark the half pins onto the tail boards.

Step 6: Spacing

Picture of Spacing

The space between half pins is divided between pins and tails. Fine work the pins 4mm > 6mm, larger work 7mm > 12mm. To have a desirable appearance the pins smaller than the tails.
Your tails should be around 18mm > 35mm for fine work like drawers and 35mm > 55mm on larger work like a chest.
Decide on your tail size remembering “One more tail than pin”.

Example: With experience we would know what we want to do but let’s experiment with this example 

I have a distance between half pins of 330mm and I have chosen a pin size of 10mm.

15 x pins of 10mm = 150mm
330mm between half pins -Total pins 150mm = 180mm
180mm total tails divided by 16 (One more tail than pin) = 11.25
AWFUL, the tail is so small. This joint would be really strong but it would take ages to prepare and would have machine cut proportions. Lets try again

10 x pins of 10mm = 100mm
330mm between half pins – Total pins 100mm = 220mm
220mm total tail divided by 11 (One more tail than pin) = 20mm
Better, this would be OK for a drawer

6 x pins of 10mm = 60mm
330mm between half pins - Total pins 60mm = 270mm
270mm total tail divided by 7 (One more tail than pin) = 38mm
Good, this would good on a chest

Set dividers to 1 tail +1 pin. Start from the half pin marks walk them across the work leaving a light pin mark.

Step 7: Square

Picture of Square

Using the square mark a pencil line across each divider mark.

Step 8: Slope

Picture of Slope

A 1:6 angle is typical for softwood a 1:7 or 1:8 angle is typical on hardwoods. Use the dovetail square or a bevel set to the right angle to mark your slopes. It’s good to mark your waste here. It will help you remember what you should be removing.

Step 9: Preparing to Cut

Picture of Preparing to Cut

Clamp the tail board in the vice. To make the cutting easier set the board to the tails become a square cut rather than an angled cut

Step 10: Sawing

Picture of Sawing

Using your dovetail saw cut to the line with the saw kerf within the waste section and cut all the way down to the base line

Step 11: Remove Waste

Picture of Remove Waste

Use the coping saw to remove the waste. Don’t try and cut to the base line, leave a little for paring. Trim the half pin waste with the dovetail saw. Cut to the baseline or leave a little to trim

Step 12: Paring

Picture of Paring

Clamp the board down. Use a bevel edge chisel remove the waste by paring down just over half the thickness of the timber. Work back to the base line with the final trim on the base line. Flip the tail board over and repeat from the other side. Undercut very slightly to allow the shoulders to pull up nicely

Step 13: Marking Pins

Picture of Marking Pins

The tail board is the template for the pin board. Secure the pin board in the vice. Use the plane to level the pin board. Rest the tail board on top. Use the plane to support the far end of the tail board. Line up the base line of the tails with the pin board and make sure the ends of the tails are flush with the pin board. Secure the tail board by applying downward pressure (use clamps if you want). Use the marking knife to create the outline of the tails. Remove pin board, square the lines, mark your waste.

Step 14: Sawing

Picture of Sawing

Use your dovetail saw to rip down the pin with the saw kerf in the waste

Step 15: Removing Waste

Picture of Removing Waste

Use the coping saw to remove the waste, as before don’t try and cut to the base line with a coping saw leave a bit for paring

Step 16: Paring

Picture of Paring

Clamp the pin board down and using a bevel edge chisel remove the waste by paring down to just over half the thickness. Work back to the base line with the final trim on the base line. Flip the pin board over and repeat from the other side. Undercut very slightly to allow the shoulders to pull up nicely

Step 17: Preparing

Picture of Preparing

Use a chisel to remove a little edge to the inside face of the tails. Make sure it does not extend to the end of the tail. This makes it easier to line up and prevents damage to the ends of the pins during assembly. Check that the base line shoulders are square on both boards.

Step 18: Dry Fit

Picture of Dry Fit

Offer the boards up and tap together with a mallet and waste piece of wood. If the joint feels tight separate the joint before going to far and trim as required. The joint should be firm but not over tight. If the joint is to tight it will split the timber

Step 19: The Finished Article

Done! All ready to fit into my tool chest.

When I clicked on this I was thinking to myself "Here's another instructable that is going to require a ten thousand dollar electronic tool I don't have access to."
Then I opened it, and you did it all by hand!
Thank you,
thank you very very much!

G S Haydon (author)mdeblasi12013-04-04

Wow! Thank you very very much!

GLFaria (author)2013-04-04

Very clear and informative!
One of the best synthesis I have read on making dovetails.
Thank you.

According to this site, dovetail is obsolete, supplanted by the box joint. For drawers, a rabbet w nails is all that's needed. The only reason to make dovetails is for looks.

charlessenf-gm (author)nhampto92017-10-31

"It took some surprisingly vigorous pounding on the wedge to cause one of the joints to fail."

Two points here. First the test is full box joint vs half blind dove tail joints. Second, one cannot imaging 'vigorous' pounding using a wedge inside any box built with either joint!

Not to mention that all the joints in the test were machine cut and that there are hundreds of thousands of examples of hundred year old furniture built with hand-cut through dovetail joints that lasted for generations without such failure as demonstrated.

There is more than one way to . . . This has been but one of them.

Be thankful that the author shared and took the time and effort to create a detailed set of instructions.

By the way, look at Frank Klausz cut these joints without measurements and a chisel and back saw:

I can't speak for the strength of dovetails in general, but the site you referenced isn't using the same type of joint as this instructable. This dovetail is cut so there's a full board width interaction between parts. On the site you listed, it's a jig-cut dovetail lookalike. I'm now curious to see how a real dovetail fares compared to a box joint.

good job

dtepper (author)2015-06-01

what's the difference between the marking gauge and cutting gauge? I'm looking to get into trying to make dovetails by hand and wasn't sure if I'd need both.

jfunderburk456 (author)dtepper2015-10-06

So I know it's been four months since your question but in the case you have not found an answer somewhere else I'll try to my best ability to explain. So a marking gauge is generally a single point, something like a small nail tip or similar to a large quilting needle or leather needle. The purpose is to just mark a line. They work well both cross grain and with the grain. Generally they are used for lying out joinery. A cutting gauge on the other hand has a blade set into the tool. The blade is similar to the one found on nail clippers but they are sharp. A cutting gauge can do a lot of the work of a marking gauge with a few limitations and some bonuses. It does not work as well when using it with the grain. Any wood that is relatively porous the blade will have a tendency to fall into the grain and follow it rather than the line you're trying to scribe. Cutting gauges do have a big advantage though because they can actually cut through things like veneer or thin stock lumber. Sorry for such a long explanation but I hope it helps.

Great! Thanks.

LesB (author)2015-08-31

One reason for using a dovetail joint, aside from the obvious structural advantage and aside from the fact it is mentioned in a Beatles song, is that is just plain beautiful.

Question: In step 13 how do you assure the two boards are parallel?

Very good job

Of everything I've built: chicken house, 10 bookcases, desk, dressers, tables, chairs, benches, headboard / footboard, etc. Not a single piece of furniture needed a dovetail joint: butt joint, lap joint, half-lap joint, etc. Apparently u know as much about dovetails as I do. At least in willing to ask the question rather than display my rude arrogance to the world. If that's your druthers, I'll help you. See my new 'ible here:

Your wish is my command. My new Instructable is done.

nhampto9 (author)2015-07-07

Forget HOW. Why?

Jogo76 (author)nhampto92015-08-21

Why? Because joinery is the strength of all woodwork. The real question is "Why would you as why?" Nevermind. I see now why. Why? Asks the guy that post instructions on how to take nails out of pallets. Maybe next you can teach us how to change a light bulb.

amekdala (author)2014-03-02

too much effort but worth it for the precise edges

thank you sharing this and ur blog

G S Haydon (author)amekdala2014-03-02

Thanks amekdala, I will be adding a video to this one soon.

mage (author)2013-04-28

bookmarked. also nice saw

G S Haydon (author)mage2013-04-28

Thanks Mage

Stay tuned for my next instructable. Wont be for a Month or two but hopefully you'll enjoy it.

cobourgdave (author)2013-04-23

Excellent instructable. I have not done one of these by hand for many years. I was seduced into the router and fence approach. This approach provides so much more satisfaction, and the results are beautiful. Thank you and congratulations

G S Haydon (author)cobourgdave2013-04-24

Hi cobourgdave,

Thanks for the feedback. Routers and jigs are brilliant and if I had heaps of dovetails to do I would use them without hesitation. However on small jobs I think there is little difference on router vs hand tools. The great thing with hand tools is that you can adjust and change at the drop of the suit the job in hand.

rammstein2 (author)2013-04-11

Is it possible to create both a dovetail and a pin on a single board?

G S Haydon (author)rammstein22013-04-11

Hi rammstein2

Thanks for the question. Not to my knowledge, I think it would be impossible to engage the joint. Have you seen any?

whit3rd (author)G S Haydon2013-04-23

If one were to make dovetail and pin on a board A, the dovetail
can engage board B with pins, and board C with tails. Then,
a long-grain glue join of boards B and C would create a strongly
locked corner, which could be useful.
Heck, with three boards (B, C, and D) you could make a
contrasting-wood stripe, both useful and decorative (or for
a drawer side, tough slider and top with a cheap poplar

G S Haydon (author)whit3rd2013-04-23

Hi Whit3rd

Thanks for leaving a comment. Sounds fun, I would love to see it. Get your tools out then send me a photo of the finished joinery.

rammstein2 (author)G S Haydon2013-04-18

Nope. I was just wondering that most of the wood is removed from the pin board. Putting both a pin and a tail on a board would have ensured that the amount of waste wood is equal for both boards.

G S Haydon (author)rammstein22013-04-18

Hi rammstein2

Thanks for the response, if you want equal waste you can adjust the setting out at step 6 for equal pins and tails. Equal pins and tails are mainly used on work where ultimate strength is the primary concern.

pierrakosn (author)2013-04-10

Thank you! Great instructable!

vincent7520 (author)2013-04-05

nice job.

Tasteywheatnz (author)2013-04-05

Those look awesome. I've tried these joints before but they didn't look as nice as yours. I guess I'll just keep practicing

LesB (author)2013-04-04

This looks like a type of project that takes not only the knowledge that you are putting forth here, but a certain level of skill. Getting the parts cut so precisely must take some practice.
I would like to try this someday when I have the time, however I think I would need to do some practice runs before being able to produce a finished product.

G S Haydon (author)LesB2013-04-05

Hi lesizz

Thanks for the feedback. You are right, some skill is involved and I recommend practicing on scrap timber before trying it on a project. Hope you find the time to give it a try and create something cool.

macmac369 (author)2013-04-03

Nice work. Do u have time to make a video clip for the whole process?

G S Haydon (author)macmac3692013-04-03

Thanks again for the kind words! Sadly I am nearly at the end of my tool chest build so no more dovetails for a while. However in the future I would like to make a video. Stay tuned for some more "How To" as I finish my tool chest build.

dana-dxb (author)G S Haydon2013-04-05

im right behaind u ?

hay_jumper (author)2013-04-04

Great job making this instructable. I've been wrestling with learning this skill, and will definitely give this technique a go at the shop. Top notch job.

ithica2012 (author)2013-04-04

outstanding job, it showes traditional craftsmenship survives, well done.

toad (author)2013-04-04

Beautiful, I have always wanted to try and make these.

Zergling_pack (author)2013-04-04

I'm not going to lie I clicked on this because of the saw. That has got to be the nicest one I've seen, where did you get it? Also great worked I was thinking the same thing as mdeblasi1.

G S Haydon (author)Zergling_pack2013-04-04

Hi Zergling_pack

It's OK, I like my saw too! Contact or visit my blog where I review the saw and provide a link to the above. They have stockists worldwide and will be able to advise you best.

orator (author)2013-04-04

I enjoyed the instructable very much. You have a very beautiful finished product that I can only dream about. Great job.

cutshopguy (author)2013-04-04

awesome. Great work and a very well put together and clear Instructable. Thanks very much.

bricmic (author)2013-04-04

Well, but why do you always dovetail with a small pin and a tail too? Strength is not good, in fact, the side pin has not enough grain of the wood to ensure strength compared to the tail side that much more. The real cabinet, as my father was dovetails much more symmetrical and more solid, see drawing. try using a press, you will see which one breaks first.
