Drawer completion...

The three drawers are fairly complete now. There is some back and forth between my bench and the cabinet to test fit each of the drawers and tune them to their respective openings, almost like a ballet. Everything went smoothly with relatively minor tuning and fitting. I don't have the drawers too tight in their opening to allow for seasonal changes in movement of the wood. I had the drawer fronts just a tad proud of the opening and dialed them in just so.

I normally don't attach the back of the cabinet until the later stages of completion, but it's been such a long time with this particular cabinet, I guess I did permanently attach the back panel months ago. The small problem this introduces is that I cannot fit the drawers in completely for there is no way to get them out again without a pull on the drawer fronts. Fortunately, the fit was so good that a strip of masking tape is all I needed to pull the drawers out from their fully closed positions.

There is considerable hand tool work involved in fitting the drawers, but relatively no dust is generated, just fine shavings. I also prepared the bottoms for the drawers by rabbeting a solid wood panel on three sides. The rabbeted portion fits into the groove on the drawer front and sides. The drawer bottoms are easily removed for any reason which might come up. I also loosely attach the drawer bottom to the back of the drawer to allow for some wood movement between seasons. In the photo, the lipped drawer in the foreground has the bottom partially installed with rabbets and grooves visible. Next I make the final test fitting of the drawers and install the cabinet interior divider I prepared in the meantime.

Drawer fitting...

The work of assembling and fitting the individual drawers into the drawer openings has begun. I work on one drawer at a time, assembling and fitting the back and bottom of the drawer. I also purposely leave the back a bit proud in order to tune the length of the drawer so that the drawer front is flush with the opening. The sides of each of the drawers are slightly proud also, just enough to be able to smooth the sides down uniformly with the drawer front. I find it important to orient the grain direction of the sides so that the grain is inwards from the front, this helps the handplaning part greatly. Also, these ever so slightly oversized measurements greatly reduce the chance for error in fitting and it all works out in the end.

I have also installed the rabbeted backs and pinned them to the sides, greatly enhancing the strength of the joint. The bottoms are custom fit to each drawer although most of the drawer bottom measurements are almost identical. I have oriented the grain of the drawer bottoms from front to back, this will allow for expansion and contraction of the bottom, or wood movement.

In the photo, the drawer at the front is the lipped drawer. I have left this one for last as fitting it involves an extra step of tuning the drawer front for a perfect fit with the lower drawer of the right hand drawer compartment. Most of my handplaning is done over at my bench at the other end of the shop and all of my dovetail work on this bench, I think it has mostly to do with the height of the benches, this lower one is more conducive to dovetailing, at least for me..

Drawer joinery...

Over the past day, I have been creating the joinery for the cabinet drawers. The joinery at the front is half-blind or lapped dovetails, whereas the back of the drawers is assembled with pinned rabbets. In the photo I have created grooves for the bottom in one drawer. The location of the groove is situated over a tail so as not to cut into the corresponding pin of the drawer front. A little trial and error measurement is necessary here, but it all works out in the end. The drawer sides have been purposely left a bit longer than necessary to be trimmed later and fitted with the drawer back. I will continue to work on the other drawer components and leave the lipped drawer last, as the measurements and offsets on this particular drawer are differently located. I like to plan ahead when creating dovetail joinery and mark all the components extensively, including the board orientation and reference faces and edges. It is very easy to get confused otherwise, not that it's ever happened to me :)

After completing the drawer shells tomorrow, I will make the drawer bottoms consisting of edge glued hardwood planed down to a fraction of an inch, to easily fit the drawer grooves. I should have everything including drawer bottoms, assembled and glued later tomorrow. There is some tuning and fitting involved for each drawer both at the sides and front to back. The drawer pulls come next and I'm currently giving this thought.

The combination of beech cabinet and sapele drawers actually work out very well, there is contrast but not overwhelmingly so, more on the subtle side. My other choice was to use cherry for the drawer fronts, but I have been using this extensively lately and wanted something different.

Drawer fronts...

I've been busy gathering the right wood for the drawer fronts, sides and bottoms. Drawer fronts will be Sapele, a fine-grained wood in the mahogany family. As part of the drawer front fitting, I cut the fronts oversize in thickness, width and length and then proceed to shoot the ends so they fit the drawer opening just right. I follow the same process with the width of the drawer front, handplaning and tuning it down to size. Prior to this, I had planed the thickness of the drawer fronts to fit the opening. The drawer front of the upper right hand set will overhang the divider providing a seamless look, I designed the divider to be shorter than the drawer opening by the thickness of a drawer front. Next, I begin dovetailing the drawer sides into the fronts and then create the grooves for the drawer bottom, in this order. Important to position the groove correctly over a tail so the groove doesn't exit through a pin in the drawer front. This would preclude using a stopped rabbet instead of a through rabbet.

I'm glad to have completed the stand as the cabinet has been occupying a cool rolling cart I built a few months ago. I now have access to my rolling cart once again, which by the way I'm kicking myself for not having made earlier. These things are great in the shop, allowing me to wheel components around to different benches and assembly tables, etc. Also, I haven't decided on the drawer pulls just yet, preferring to wait a few more days and examine some options in the meantime.

I'm also going to install a short divider between the sets of drawers creating more of a delineation between the left and right sides of the cabinet interior. The area above each of the drawer compartments is to be used to display an art object , the divider perhaps will separate the styles of art objects? It just feels right.

I'm still not sure how to work the area below the left hand drawer compartment into the mix. The design of this has been up in the air for a while, and I'm thinking once the drawers are in along with the divider it will make more sense and a a spark of imagination will occur, an "aha" moment. I'm leaning towards a hidden compartment at the moment. Or I might leave it open, in the spirit of "dynamic design", a philosophy I coined a few months ago.

Cabinet stand...

I assembled the stand and am test fitting it in the photo a few hours after glue up. It fits well and is in very good alignment with the cabinet. This is a concern otherwise the stand looks more like an afterthought than designed with the cabinet if it doesn't fit right. The twin stretchers at the bottom work out well and introduce a small focal point into the design. It is quite a small feat getting the rails and stretchers in position for the glue up and a good point to stop and plan this out well. I assembled the sides initially, then put everything together with the front and rear rails and stretchers. The upper and lower rails are mortised into the legs with single tenons, whereas the twin stretchers are dowelled into the bottom side rails.

I am quite pleased at the aesthetics of the piece and the harmony between the cabinet and stand. I needed to spend some time at the edge treatment phase of all the stand components. The edges of each component are slightly chamfered with a small hand plane, then the edge transition is touched with a very fine sanding block to knock out any sharp edges. Since this is all done by hand, I find myself counting the exact number of strokes with the hand plane, in this case two. It is recommended that all the components be completed in one pass to avoid confusion. In other cases, where multiple passes are necessary, counting the handplane strokes is a good technique.

The stand is also beech and all the front and side facing components have non-descript grain pattern, straight grain for the most part, to not introduce any crazy graphics which take away from the main focal point, the cabinet.


I'm kind of anxious at this point to complete the interior of the cabinet, create the drawers and a small partition, then the pulls, so I can begin to apply finish. I'm curious to see how the figure of the door panels comes out. Of course, I can always wet the surfaces with naptha to temporarily see the figure pop, but I can wait a few more days.


I had a little deliberation deciding on the final height of the cabinet and settled for a 55 inch height , along with a second opinion from my better half. Having the piece too low and it begins to look like a credenza , too high and the stand begins to look spindly. I also wanted to provide an opportunity to see the cabinet as a whole, including a partial view of the top. Accessibility and visibility of the cabinet interior is also important as this is somewhat of a showcase cabinet, and my wife and I did take this into consideration.

Cabinet stand...cont'd

I have resumed work on the beech cabinet in the past few days. I've rethought the design of the cabinet stand and made some changes. The original design called for four upper rails mortised into the legs. I would need to have wider front, rear and side apron rails to maintain the strength and integrity of the stand. Rather than this, I have decided on narrower top apron rails and move some support to the bottom of the stand in the form of stretchers instead. The aesthetics of this are more pleasing to me, very much like dividing the load at the top and bottom of the cabinet stand.

The leg dimensions remain the same, instead I divide the original upper rails into two components per rail and use the narrower component at the bottom of the stand. The strength and integrity of the cabinet stand should be maintained with this design along with more pleasing aesthetics, and more subtle, smaller components. I should have the stand assembled within the next day or two. In the meantime, I need to replace one of the components in the stand, a front top rail. In the handplaning effort I was a bit overzealous with this particular rail and the dimensions are no longer right, a little too thin. Rather than handplane the other rails to this dimension, I would rather replace this rail instead.

With significant hand planing, it becomes more important to maintain keen edges on the plane irons. The dullness of the irons sneaks up on you, and before you know it the handplane is struggling to produce fine shavings. I stop occasionally to sharpen the plane irons, otherwise the temptation is to increase the depth of cut with dull irons and all of a sudden they grab and tearout follows.

It's amazing how much the weather has changed in the span of two to three weeks in these parts. It was early fall weather a few days ago, now I hear some wet snow is arriving overnight. It should be nothing significant and late fall will resume, I hope.

Off on a tangent...

I had some spare time recently while waiting for finish to dry and thought I would experiment with some inlay techniques. I have always found a piece of inlay with a surrounding border to be fascinating to be able to make. I need to confess, I've done this before although quite a while ago and need the practice. What I had in mind is a fair sized yellowheart diamond with a black border, I used blackwood. I have the inlay set in a lighter wood, nothing special, just a small offcut. The process of creating and inserting the inlay is a very good test of patience and fine hand tool skills , for almost everything here is accomplished with hand tools.

The border itself is bandsawn from a larger piece of blackwood and the yellowheart also bandsawn from a solid block. The yellowheart inlay is first drawn out and cut with careful attention to the shape of the diamond, each of the sides and facets needs to be a mirror image of the other side. I then mark the inlay onto the lighter background wood with an allowance or margin for the surrounding border. Once marked with a fine knife, I then remove or carve out the recess for both the diamond and border. Next step is to fit both the yellowheart inlay and blackwood border into the recess with glue , make sure it is well seated and wait for everything to set. Afterwards, I judiciously handplane the inlay and the result is in the photo at top. I find it great therapy to go off and do some other type of woodworking during or after some intensive furniture making, it clears the mind and the instant results can be very gratifying, the practice also keeps the skill retention up...

Back panels...

Much of my cabinet design and build process involves the creation of a cabinet back. Conventional wisdom says the back of a cabinet is not nearly as important as the front or sides, so it merely needs a panel which is rabbeted into the sides, top and bottom. The problem with this thinking is that it assumes the back of the cabinet will be placed against a surface or wall and never seen. This doesn't apply to all cabinets as many cabinets are designed as showcases which are away from walls, sometimes placed in the center of a room or even a foot or two away from a wall. Something also feels wrong about diminishing the importance of the back of a cabinet when so much emphasis is placed on the design and structure of the front and sides of the cabinet. With this in mind, the need for a more aesthetically nice cabinet back becomes important, along with the function that it introduces to the cabinet. An example of function is if the cabinet is a wall-mounted cabinet and needs a structurally strong back.

The resulting back panel which best meets the criteria of both aesthetics and function is the frame and panel back; a panel inset into a surrounding frame composed of rails and stiles. The frame and panel back is inset into the cabinet back much like a panel would be and in the process the frame and panel also provide some rigidity to the cabinet. In those situations where a single panel is too wide, a middle stile is installed to divide the frame into two halves, otherwise for smaller cabinets a single panel is sufficient. The panel itself can either complement or contrast the cabinet, providing an interesting focal point once the doors of the cabinet are opened, as well as drawing the eye to the pleasing back of the cabinet.

Dowelling technique...

In many of my cabinet assemblies I use dowels to attach the sides to the top and bottom. The use of dowels gives flexibility to the design of the corner joint. For example, I can offset the side panels away from the edge of the top or bottom and in the process work the protruding edge of the top and bottom into a shaped contour, chamfer, rabbet, etc. The alternative would be to use specific corner joints which need to have the side panel and top or bottom panel intersect right at the very edge. An example of this would be a dovetailed joint, a box joint, or a rabbet and lip edge. If you've ever read up on James Krenov and his work, you will find that he embraces the dowelled corner joint for these very same reasons. This is where I received the inspiration for this type of joint and its virtues.

Creating the doweled joint involves some measurement , but most importantly it involves the little jig you can see in the photo, the dowelling guide. This is a piece of wood with the exact dimensions of the panel I am dowelling, the length and thickness. The dowel holes are marked with arbitrary spacing and the dowel guide holes are bored out on the drill press. I use this dowelling guide to create the dowel holes on both of the mating surfaces , in this case the side panel and the top or bottom panel. There is some skill involved in aligning the dowelling guide to both surfaces since the holes for the dowels need to be perfectly aligned. Marking and orienting the dowelling guide to the correct edges becomes very important and I make many pencil marks in the process. The old adage, "measure twice , cut once" becomes "measure and mark three times, drill once". in this process.

Under wraps...

These past four weeks I have been working on two new pieces of furniture. The first is intended for a gallery exhibition and the second to be entered in an upcoming local furniture exhibition. Unfortunately I will not be able to share the design and build of both these pieces for a while. The second piece intended for the exhibition, is essentially under wraps as all entries need to be in and judged by a certain date. I can say that I am really enjoying creating these two pieces as they are purely on built on speculation and I therefore have complete carte blanche on what I make.

Once I have completed these two pieces I will continue with the beech cabinet on stand which is currently on the back burner. I would estimate I can continue my work on the cabinet on stand in the first week of October. The two pieces I am working on are purposely not very large so I can instead focus on some extra detail I can hopefully incorporate into the design. Sometimes we need to take a leap forward and move into uncharted design territory to be able to add new skill sets and techniques to our furniture making repertoire. We need to regularly challenge ourselves. Wood selection has been a bit of a challenge lately as I have a difficult time locating wood with nice grain and good graphics. Most of what I find is suitable for cabinet work and not so much for fine furniture. Veneering becomes more of a viable option to circumvent this issue. Once I have boards with ideal grain pattern, graphics or figure in my hands I can simply slice veneers from it to use as components of furniture I am creating.

Cabinet base (2)...

I have let the components of the cabinet base or the cabinet stand sit for a couple of days to have them release any internal tension from the resawing operations performed earlier. This tension is due to the interior part of the wood not being as dry as the outside , therefore typically contracting inwards to form a concave form. After a day or so I began to plane the legs a small amount to create flat reference surfaces on two adjacent sides. I then use these perfectly flat sides to dimension the legs to the proper thickness all around. This is one area where it is best to take the time and do it right regarding the judicious dimensioning. I monitor the leg stability every so often, making sure there is no bowing or twist occurring from pent up tension. Th extra material I had left in each dimension would allow me to remove this safely if it does occur. I have also highlighted the grain orientation of the legs and aprons.

I also have the parts for the four aprons almost ready, they are rough dimensioned at this stage with a flat reference surface. I also check this flat reference surface periodically to confirm that it is still flat and not cupped, bowed, etc. When these base or stand components have stabilized further, I will dimension them to the finished sizes. Afterwards, I introduce a taper to each of the legs which I perform initially with the bandsaw and then handplaning the surfaces flat. I also have the blank for the drawer faces selected. The blank is a straight, fine grained Santos mahogany and from it I will rough cut three drawer faces.

Well, it's that time of year again. My wife and I are off to the mountains for a few days of hiking, kayaking and relaxing. With our warm and humid summers up here, we like to go to the mountains as it's cooler and drier. I'll continue where I left off when I am back.
