Introduction: Making a Wooden Drawer

An article on Wooden Drawers by Ian Taylor.

Nowadays we take drawers very much for granted. They appear everywhere in the house; in the kitchen, the bedroom, the study and the workshop. They come in different sizes and designs. Some have mechanical slides and others run on wooden supports (called runners). But they all have one common feature: they are basically open-topped boxes that can be accessed separately and conveniently.

Step 1: Drawers in History

Picture of Drawers in History
It wasn't always this easy. Until the late 16th century, clothes, bedding and other important personal items were all stored in chests and coffers large boxes with hinged lids. They kept things clean and tidily out of the way, but there was one big drawback. If you wanted something from the bottom of the chest, you had to take everything else out first.

Towards the end of the 16th century, this weakness began to be addressed. It occurred to furniture designers that if you stack a set of smaller boxes inside a bigger box, and make sure that they are accessible from the front rather than the top, you can go straight to the items you want without unpacking everything.

To begin with, chests incorporated just a single drawer in the base, but by around 1650, drawers had become a common furniture feature and the chest of drawers, as we would recognise it today, had arrived.

Step 2: The Traditional Way

This article concentrates on the construction of a conventional flush-fitting wooden drawer to be used in a small wardrobe. Next month we'll review some of the variants in drawer design; cock beads, drawer slips, overlapping fronts, mechanical runners and so on.

The drawer we're making here has a traditional dovetail construction and a solid timber bottom. The front is oak, to match the wardrobe it will be part of. The sides and back are ash, this gives a nice contrast to the oak and shows off the dovetails. The bottom is Cedar of Lebanon, which has an aromatic smell when newly worked. The handles are hand-turned knobs, made from American walnut, giving a nice warm contrast to the oak.

Step 3: Front First

I always start with the drawer front. Make sure it's not twisted or bowed, and trim it to width and height to fi t the drawer opening. It needs to be a loose fit to ensure that it doesn't bind in operation. Aim for 0.5-1mm clearance at each side. The top-to-bottom clearance depends on the depth of the drawer. A shallow drawer can be a tighter fi t to its opening, because any seasonal expansion will be small. On a 200mm deep drawer like this one, I aim for about 1-1.5mm clearance. You'll need to edge towards the correct fit, particularly on width, and to check the fit in the cabinet regularly as you work on it, photo 1.

Step 4: Equal Sides

It's important that the sides are of equal length and that their ends are square to their long edges. A shooting board is very helpful in ensuring square boards, photo 2. The back also needs to be squared up. It should also be the same length as the front, though some choose to make it a touch shorter so that there is no risk of the drawer binding. I usually don't bother with this refinement. For reasons described later, I usually start with the sides a couple of millimetres wider than the front.

Mark up the tails on the sides first. For the front dovetails, the depth of the tail needs to be marked up on the sides and the ends of the front board. Do this with a single setting of your marking or cutting gauge, photo 3. Reset the marking gauge to the thickness of the back and sides and mark up the rear faces of these components and the inside face of the front, to define the base of the joints. For a good balance, the dovetail positions can be marked up on the sides in pairs, photo 4. Mark up the dovetails from these positions with a sliding bevel. The tails are cut with a handsaw, photo 5, and chopped out with a chisel, a pretty quick job, photo 6.

Step 5: Tail Transfer

The next stage is using the tails to transfer the dovetail positions to the ends of the front and back. I use one of the sides to support the other in this job. Set up the front vertically in the vice and align its top edge with the supporting board, photo 7. Then place the other board on top of the first one, take care that it is centrally positioned and mark the joints with a sharp pencil, photo 8.

My approach has the sides about 2mm wider than the front, so there's a 1mm overlap at each edge. I've found that if you start with the boards exactly the same width as the front, any imprecision in marking or cutting can leave you with the boards misaligned, an undershoot at either the top or bottom and an overlap at the other, which has to be planed off. But you can't easily fix the undershoot. So I aim for a small overlap at both sides, which is then planed back. Not only does it give a neat job, but it's easy to ensure that the drawer sits squarely on its runners. This isn't what the textbooks say, but I find that it always works for me.

Step 6: Crafty Knobs

For this drawer, I wanted plain hand-turned knobs, to emphasise its handcrafted appearance. You could turn knobs with fl at bottoms, for mounting with screws, but I like turning a dowel end. Each handle has an integral 12mm dowel to slip into a mating hole in the drawer front.

For a neat fit, you need to be sure that the dowel holes are drilled perpendicular to the face of the drawer front. This can be difficult to achieve drilling freehand, so I use a simple guide block drilled on my drill stand to ensure right angles. If you use a lip and spur bit, you can be sure you are drilling in the right place. Position the bit on the mark before sliding down the guide block and starting drilling. A piece of scrap clamped to the back ensures no tear out where the bit emerges.

Put a smear of glue around the inside of the hole and press the knob home. I drive a wedge into a slot cut in the dowels, to ensure a really tight fit that won't work loose over time. Make sure that the wedge is at right angles to the grain of the front to avoid the risk of splitting. When the glue is dry, cut off the excess dowel with a sharp chisel and sand it smooth.

Step 7: Chopping Times

After you've squared the dovetail positions down the rear face of the front, you can start chopping out the waste. Be careful to cut on the waste side of the lines and aim for a bit of trimming to get a tight and neat final fit. Define the angles with a backsaw, photo 9, and set to the chopping. This is a fairly slow job, especially working in a tough timber like oak. It took me up to 10 minutes for each of the dovetail recesses, photo 10, so around 80 minutes in all.

You could speed it up by using a router to remove the bulk of the waste, but it's very easy to make a costly mistake, especially as you're cutting freehand. In this case, a bit of tough handwork was good therapy. Apply the same process to the dovetails on the rear panel. As they are through dovetails, and in an easier timber, this is a much quicker job to carry out.

Step 8: Testing the Fit

You'll need a bit of fine-tuning to get a good fit on the joints. Once you're happy, trim back the sides and back to the correct width, making sure that you are maintaining a right angle between the bottom edges of the side and the front of the drawer. When you're happy with that, rout the grooves for the bottom, taking care that you've got the right position relative to the rear lower half dovetails – see the Drawer details panel on the previous page again.

Step 9: A Drawer Is Born

You can then glue up and clamp the drawer, photo 11. Make sure that the diagonals are equal as a check that you're gluing it up squarely. When the glue is dry you'll need to plane and sand the sides to a clean finish, photo 12.

With the drawer assembled, check the fit in its opening. If all has gone well it should fit first time, but don't be surprised of there is a bit of trimming needed to get an easy sliding fit.

For example, the opening might be slightly narrower at the back than at the front. Once it's sliding nicely, push it fully home and check that the front is flush with the face of the drawer opening. In my case, it stood a bit proud at the bottom left corner.

If this happens, mark the corner with a pencil where it stands proud, photo 13. Remove the drawer and plane back the drawer front to your pencil lines. If you've taken care that the front panel was flat, any adjustments you need to make will be only minor, as it was in my case.

Step 10: Drawer Details

The joints at the front of this drawer are straightforward half-blind dovetails, so that the drawer front appears unbroken when closed. At the back you can use through dovetails, which are much easier to cut.

However, the layout at the back needs a bit of thought, because it's central to the structure of the drawer. The base fi ts into grooves cut in the inside faces of the sides and the front. The dovetail design needs to accommodate this. The diagram (left) shows the side and rear aspects of the back dovetail joints. The bottom rear joint is a half dovetail, sitting immediately above the groove for the drawer bottom. The back of the drawer is not as deep as the sides, and butts against the upper surface of the drawer bottom.

If you plan this carefully, you can rout the grooves in the sides and front straight through, without stopping. This makes the job very easy and neat. The pictures show the groove geometry I used for this drawer and demonstrate the construction principles. The grooves in the side run through the bottom front dovetails and are hidden in the assembled drawer. On the drawer front, the matching groove runs into the dovetail cavity, also hidden. At the back of the sides, the groove lies directly below the bottom half dovetail.

Step 11: Back to Front

Finally, slip the back panel in. In a traditional drawer, the grain in the bottom runs from side to side, so any seasonal movement will be experienced in the back to- front direction. If the grain ran back to front, seasonal contraction and expansion could either pull the bottom out of the groove, or put pressure on the sides so that the drawer locked tight in its opening.

The drawer bottom needs to be screwed in position to the underside of the back panel through slots, to allow for this potential movement. Take care that the back is square and that it fits easily into the groove. If it doesn't, you'll run the risk of forcing the drawer out of square and jamming in the opening. If there's any tightness in the drawer at this stage, take out the bottom and do a little fine tuning.

That's it, ready for finishing and polishing. There's a lot of work in making a drawer. It needs careful measurement and planning, and a lot of handwork. But if you do it well, you know it's going to last for years, and your hand-cut dovetails will be proudly on show every time its opened.

Never knew they were called dovetails. Funny, in Dutch they are called swallowtails.

Interesting.

Thank you very much. I've a project with making an replica of an old toolbox found in New Mexico from the 19th century -- and this illustrates exactly how to do it by hand. Too smooth, too cool.

I believe you are confusing your pins and tails. In a single joint, dovetails existing on one piece only. The other piece holds the pins. The side view in step three shows the tails as the wider part, not the narrow parts as you have identified. The parts you call half dovetails are actually the pins.

hundred or a million times better than a ikea prefab thing that commonly build for 4jears
but this is a real nice handcrafted drawer. thanks for sharing it.

Thanks for reading!
