carcase doweling

Consider the options for joining solid wood boards across their widths where the endgrain of one board meets within the length (not at the end) of the side grain face of the other. This is what you see in the pieces above and just below, which are constructed with dowel joinery.

A common situation is joining the sides of a cabinet to the top and bottom where the boards do not meet at the end of each. If they did, dovetail joinery is usually the best choice. Another common situation is an interior divider or fixed shelf of a cabinet or bookcase.

Before delving into the topic of this series, here are some alternatives that might be used in the same situation as carcase dowelling. By the way, this series is not about post and rail joints with dowels, a different matter with its own considerations. 

1. The multiple wedged through mortise and tenon. This has plenty of side grain glue surface and the flared mortises coupled with the wedged tenons provide a mechanical lock. It does take a lot of work though, and the exposed wedged tenons may be a nice feature or unwelcome. The blind version of this joint is an exercise in masochism.

For an efficient method for this joint, see my article in Popular Woodworking, issue #170, August 2008, pages 62-65.

2. The tapered sliding dovetail. This provides a strong mechanical lock, and can be made efficiently with careful router setups and a bit of fine tuning by hand, though it does take some trial and practice to get it right. It can be designed to be invisible but only at one end. 

3. Nails and screws. We do not usually associate this approach with fine woodworking but not everything has to be high end. I have a 44 year-old large bookcase held together with nails and it is still rock solid. The nails are hidden (mostly) with the technique of raising an attached chip, driving the nail inside the tiny ditch, then gluing down the chip. I can do better now, but it’s not bad. 

Covering the heads of screws with side-grain tapered wood plugs is a decent option in plywood and could pass in solid wood utilitarian work if done judiciously.

4. Hidden knockdown fasteners such as cam fasteners. Nah, not where I want to go in solid wood; weak. 

5. Dado joints, fully housed or shouldered. Here we have no mechanical lock and no mating of side grain glue surfaces. Biscuits or dominoes would help but I still would not bank on the strength. 

OK, with the other options noted, let’s go ahead and look at the carcase dowel joint. Part 2 is coming up.

wooden drawer handle

Here are some thoughts on handle design that I hope you will find useful for your work.

We experience several aspects of woodwork at once – design, spatial sense, texture, color, sound, smell, style reference, etc. A hand-friendly handle can be a significant addition.

Exotics such as the Macassar ebony, above, are my favorites for handles. They finish beautifully and wear well. Note the stand out from the surface of the piece. This avoids finger grime from building up on the surface of the woodwork.

I almost always want a shape that is directly consistent with the design of the piece. In fact, the curves and proportions of the piece tell me how to shape the handle. I rarely want to introduce a new theme in the handle, though that might work more often for designers more talented than I.

The cabinet handle below is shaped much like the cabinet itself. The hard edges on the top will not be grabbed but the hard edges on the sides have a nice feel, especially since the sides are undercut.

Below, the very simple small chest handle in wenge is in keeping with the simple design of the piece that relies mostly on the beauty of the wood, pleasing proportions, and the joinery for interest. The underside of the handle is slightly hollowed to make for a nice finger grab.

Below, this wall shelf with a side-hung drawer has so much going on with the wood species and figure, plus the undulating surface on the drawer front, that any further statement from the handle would be too much. The simple brass knob fits the bill.

This drawer handle, below, in Honduras rosewood, borrowed shamelessly ripped off from a design by Michael Fortune, also fits with the gradual curves of the cabinet. (Hey, I did add the bowed front, which made it a lot more difficult to make.) Speaking of “borrowing,” I will be nothing but flattered if you borrow any of my designs shown here.

The length and bulk of the handles are graduated to be consistent with the graduation in drawer sizes. Yes, that took a lot more work.

Lee Valley offers graduated-size metal handles in a variety of finishes.

Finally, sometimes it is fun to introduce something different, such as these manufactured handles, which have been on my tool cabinet for a very long time.

Give it a try – enjoy enhancing your work with custom handles. Keep in mind too, that thoughtfully selected manufactured handles also can go a long way to add to your woodwork.

making wooden handles

When sculpting the handle, keep the workpiece large for as long as possible. Of course, at some point you will have to cut loose the handle itself but the work becomes more difficult on the smaller piece, which may be impossible to clamp. 

Decide early on if you want a knife-cut finish or a smooth, sanded finish. Work for a good appearance but also keep testing the feel of the handle.

The finished handle in wenge is shown above mocked up on a piece of white oak scrap. (The scrap was used to test an edge profile; it is not a door). Note the hollowed left side and that the curved right side is also sloped toward the door. These features make for a pleasant grab by the thumb and first two fingers.

A hand-friendly handle does not necessarily mean that all the edges must be softened as they are here. Sometimes a distinct edge or corner feels right.

Create shoulders on the end of the tenon. The mortise, created with a shopmade slot jig for the router, is 1 1/4″ long and 3/8″ deep.
