Six Pane Oak Hutch

 
 

Six pane oak hutch isometric view.The "six pane" in six pane oak hutch refers to the number of glass pieces in each door. TheSix pane oak hutch front view. glass pieces are sometimes referred to as lights because they let outside light in to display the contents. Hutch is the name most used in contemporary times when referring to this type of furniture. But historically this would be called a hutch cupboard, cupboards being any piece of furniture used to store things. A hutch is a cupboard with drawers and shelves. The shelves could be open as in "open hutch" or enclosed with doors as this one is.

This hutch is constructed from quartersawn white oak which has a more attractive figure than red oak due to its larger rays. These rays are enhanced by the quartersawn material.

Overall dimensions are 52"W x 88"T x 18 1/2"D. The front view is nearly a perfect golden rectangle, an aspect ration most pleasing to the eye. The hutch is built in two pieces to make moving it easier. There are three shelves in the enclosed top case (two fixed shelves plus the bottom) that are grooved to support plates that stand against the back.

The opening between the upper case and the lower cases top (called a pie shelf) was traditionally 4" to allow for pies to be placed there. More contemporary designs increased this dimension to 8", but in this design it has been increased to 12". ThisSix pane oak hutch side view. will allow for a groove in the top to also support vertical plate displays of plates as large as 12".

The panes in the upper doors are traditional divided lights, six individual panes in each door, not a single pane of glass with imitation divides. The three horizontal drawers are constructed using hand dovetail joints with solid beveled bottoms. The lower doors are constructed using mortise and tenon frame and panel construction, with beveled panels.

The crown molding is made up of traditional cove molding sandwiched between a quarter-round on top and a delicate bead on bottom. The feet are custom ogee.

Note:
The pictures you see above are not photographs but rather 3D rendered drawings. I design all my furniture using TurboCADTM Professional, a 3D design and drafting tool. This enables me to see how the final milled parts will go together without actually building a prototype. In addition to saving time and material it provides me detailed drawings and renderings which aids in making design trade-offs. Changes during this stage are also easy and inexpensive.

The first four steps in any project are: 1) make the plans, 2) acquire the rough lumber, 3) plane & square to rough dimension (called rough to ready) and 4) join, glue-up and flatten panels. These four steps entail a lot of work and require good woodworking technique. However they don't begin to show the shape of the piece nor highlight the joinery. So I have skipped these steps in this discussion and instead have started with dovetailing of the carcass panels.

Work secured to raised bench with clamps.Normally when I cut dovetail tails I place the work in a bench vice. I can adjust the height for a comfortable working position and secure it so that there is no chatter when I cut. However, this piece is 18 1/2"W x 49"T and the tails have to be cut on the 49" end. My bench is 34"T leaving 15" of material which will allow chatter when cutting. In addition 49" is a rather tall piece to cut while standing on the floor. Luckily I have a bench that can be raised to 44 1/2" and with the help of some clamps the work can be secured to the bench at a height where I can cut chatter free. See photo at left.Tails are marked with an X showing the waste material.

After securing the work I mark the tails making sure to also mark the waste area with an X. When cutting a long row of tails it is very easy to get disoriented and cut away the wrong material. This step of marking the waste pays dividends even for seasoned woodworkers.

As previously mentioned, cutting the tails at a height of 49" while Using a step ladder I can comfortably cut the tails.standing on the floor is almost impossible. It's at times like this that a step ladder comes in handy. Standing on the first rung I can cut the tails quite comfortably. However, I have to reposition the ladder every couple of cuts so that I can maintain a proper stance and arm motion.

There are two features of the tail cut (when cutting them before pins) that are critical. First, the cut must be precisely perpendicular to the face of the work. Failing to do so will leave unsightly gaps, poor glue joints and weak mechanical joints.Cut must be perpendicular to the face and nominally +-8 degrees from vertical. Second, you must stop the cut on the scored line marking the cut depth, and this must be true of both faces. The angle of the cut is nominally 8 degrees from vertical, but this is not critical. Neither is the width of the gap (pin width). Machine cut dovetails would all be perfectly angled and spaced, but then they would look machine cut. The human is not a machine. Hand cut dovetails are beautiful precisely because they don't look machine cut, they are all slightly different, adding to the beauty of the piece.

Waste is cut away using a fret saw.After cutting the near vertical cuts with the dovetail saw a fret saw is used to remove the waste. The goal is to cut as close as comfortable to, and parallel to, the scored line marking the waste depth. Leave just enough material such that the score line remains un-bruised. In order to make this cut the blade has to be "twisted" in the saw so  that when the blade is cutting parallel to the score line the saw is angled up enough to clear the tails. This is easily done with the help of a pliers.

A side note. There are two stars of the hand cut dovetail show - the dovetail saw and the chisel.The chisel is placed in the score line and struck with a mallet to clean the waste. The dovetail saw must have a thin kerf to make precise cuts, a rigid back to keep the blade straight and fine enough teeth to leave a clean cut. The chisel must have a finely honed micro (or secondary) bevel to give it the sharpness required to cleanly cut hard wood. It should also be made of good steel appropriately hardened and it must comfortably fit in your hands. I use a western style Lie-Nielsen dovetail saw. I have both Lie-Nielsen and Marples (now called Irwin) chisels and use them interchangeably.

Finished tails.The score line is scored at a depth equal to the thickness of the mating pin board. A dovetail chisel is used to clean out the waste. The chisel is placed in the score line and struck with a mallet to make a perfectly straight and vertical cut. This cut is made half way down on all waste areas. Then the board is flipped and the waste cuts finished from the other side.

The finished tails look like the photo at above left. Note a few things. Most important the walls of the tail are perpendicular to the faces and the cuts stop at the score line. Note also that I cut a little off line in a couple of place. That is not a problem because the mating pins will be marked using their mating tail and all will be happy. Compare hand cut dovetails with machine cut and see which you like esthetically. Hand cut wins - hands down - every time.Pin cleanup with chisel and mallet.

The waste has been removed and pins are ready for chisel cleanup.The tails are used as a mask to mark the pins. The pins are then cut with the dovetail saw and the majority of the waste is removed with the fret saw, just like the tails. The rough cut pins, shown left, are then ready for cleanup using a sharp chisel and mallet shown right. When cutting the pins it is important to leave the pencil marks while cutting on the waste side of the line as shown in the up close picture below left. This is because the tails were used as masks, therefore everything under the tails must be removed. However the pencil mark is just outside the mask and is actually part of the pin. The completed pins are shown at right below with mating tails. You will have to wait until I glue up the entire carcass to see how well the pins and tails fit together.

Leave the pencil marks when cutting the pins.Hand cut dovetails are time consuming. On a project such as this there are over a hundred dovetails (a dovetail is a pin and tail combination). Each dovetail takes six cuts and two chisel cleanups plus measuring and marking. That's in excess of 800 manual operations for dovetails alone. So why cut them by hand instead of by machine and jigs? Because they are beautiful when completed.  The woodworker has muchFinished pins next to mating tails. more control over the size of the pins and can vary them at will. And I believe hand cut half-blind dovetails are actually stronger than their machine and jig counterparts, though that will take a project in itself to demonstrate. In addition, as a woodworker, it is a connection with the craftsmen of the past that tugs at you, it's working in a dust free shop void of power tool noises and it's the closeness to the wood that you feel as you shape it with your hands. While I wouldn't exchange all my power tools for hand saws, I do take every practical opportunity to use hand tools to shape and join wood.

Drawer framework showing supports, sliders and dividers.The drawer framework, shown in picture at left, consists of drawer supports (horizontal rails dovetailed into the sides), sliders (running front to back in the same plane as the supports) and dividers (sitting on the sliders to guide the drawer). Note that there are three drawers, each drawer divided from the other at both top and bottom. The dividers will guide the drawer to keep it from jamming when opened or closed.

There is a problem associated with this style of case construction. Wood Movement Master by Kite Hill SoftwareThe wood grain of the carcass runs vertically on the sides and horizontally along the top, in both cases parallel to the front and back surfaces. This means the carcass will expand and contract in depth with changes in seasonal humidity. If the drawer framework were one structure glued to the sides of the carcass, either the framework could be pulled apart with this movement, or the sides could be split. Since we want this piece to last for generations we have to find a solution to this problem.

To deal with it we must first know the extent of the problem, or in this case the extent of the expansion/contraction of the sides and top. I use a CAD tool called Wood Movement Master by Kite Hill Software to help with this. If you click on the picture at right you will see calculations for white oak panels used in this application. The user enters the moisture meter he/she is using (in my case a Delmhorst 2000), type of wood, area of the country, the moisture content reading (8% in this case), type of calculation desired (Board-centric meaning board expansion/contraction), how the wood was sawn (quarter sawn in this case), number of boards in the glued up panel and the width of each board. Then press calculate and presto! The results tell me that each 5.5" board will move a total of 0.06" throughout the year, varying between 5.48" at its narrowest and 5.53" at its widest. Since there are three boards there is a total movement of 0.18" or about 3/16". If I had used flatsawn white oak the movement would have been twice that, or about 3/8".

See gap between right end of slider and horizontal support.To allow for this movement without breaking joints or splitting sides over time, I made the drawer slides "float". In the picture at left you can see that the framework is constructed with mortise and tenon joints. The front tenons are glued into their mortises and the dividers are glued to the front support and the sliders. The dividers and rear tenons are not glued to the rear support leaving them to float while riding in their mortises. In addition you will notice a gap between the rear support and the sliders (top right corner of picture) which allows for shrinkage and expansion based on the Wood Movement Master calculations. Now I can rest assured this piece will last for many generations and remain as strong as the day I constructed it.

Base face frame exploded to expose construction technique.Base face frame assembled.The base face frame dresses up the front of the base and provides framing for the drawers and doors. If I were building kitchen cabinets I would use either pocket screw or biscuit construction. With pocket screws a butt joint is secured with screws that are "toe nailed" into the joint through a pocket to allow the screw to hide below the surface of the wood. These screws and pockets are applied from the backside so they are not visible. With biscuits a butt joint is secured by first machining a semicircular mortise into each piece and then using a biscuit shaped tenon to join the pieces. Neither method provides as much glue surface area as the mortise and tenon joints I used in this assembly, shown in an exploded view left, and an Base face frame glue-up.assembled view right. In addition, pocket screw methodology relies largely on the screws for strength, since the butt joint is end grain to edge grain, which is a notoriously weak glue joint. The biscuit is somewhat better in that the biscuit provides a face grain to face grain glue joint, however the glue area is still rather small. In my opinion biscuit and pocket screw joinery are compromises that should only be used in fine furniture when mortise and tenon joinery is not an option.

Above you can see the glue-up of the face frame to the base, proving once again the old adage "you can never have enough clamps".

Shaping ogee feet is a five step process.To this point every part of this piece has been milled and shaped with straight, eight degree (dovetails) or ninety degree cuts. Its ogee feet are quite different. Ogee feet are smooth continuous curves on both the front and side. This piece requires six ogee feet. Two sets of two are required to form the front wrap-around feet plus two back feet. Shaping them from stock milled to overall dimensions is a five step process. The feet measure 6 1/8" tall, 1 3/4" thick and 7 1/2" long. I plan for six plus one spare to recover from a fatal mistake should I make one (and I actually did on this project). I start with stock milled to the finished height and thickness and 58" long which includes allowances for chop saw kerfs and other margin to be explained later. My goal is to produce the six ogee feet shown left below.

Start with shallow cut and adjust as necessary. Take small cuts.Six ogee feet are my goal. I make an addtional foot just in case.Step 1 is to shape the major concave curve. This is achieved by passing the stock over a table saw blade at an angle as shown right. The angle can be calculated, but it is easier to draw the desired shape on the end of the stock, start with a shallow cut and adjust as necessary. The subsequent cuts must be small and the feed rate slow since this is not a cut the table saw is designed to make. But careful attention to safety and patience will produce the desired shape. A slow feed rate also produces a smoother cut. This is important because the shaping of this cut is completed by hand sanding, which can be long and tedious if you feed the stock too quickly. It further helps to use a blade with a flat top grind since it also  enhances the cut's smoothness. Safety consciousness is crucial here because the blade is exposed. After completing the table saw shaping the surface is hand sanded starting with 120 grit and proceeding through 180 grit.

Step 2 is to cut the half-round on the front along the length of the stock. I used a table mounted router with a half-round bit. It is important to make this cut such that the thickness of the stock remains 1 3/4" when it is completed (see drawing above). This is critical because later the stock is placed shaped face down on the band saw to create the side curves.

Shape the convex curve with a table saw cut, block plane and hand sanding.Step 3 is to shape the convex portion of the profile. I start by cutting the stock along its length at an angle tangent to the right or outside half of the curve (see drawing above). Adjust the table saw blade angle to provide the maximum benefit to the final shaping. Next I secure the stock on the bench with clamps and shape the curve using a small block plane. My favorite plane for this task is the Lie-Nielsen 102 Low Angle Block Plane. If the stock is highly figured a higher angle block plane may be required to avoid chip out.The side profile is rough cut with a bandsaw including the half round.

I finish with hand sanding proceeding from 120 grit to 180 grit. I now have a 58" long ogee shaped stock that I cut into 8" length pieces. Remember that the final foot length needs to be 7 1/2", but four of the finished feet need a forty-five degree cut to wrap-around the front corners. I like to approach this cut slowly in several incremental cuts. So I leave myself 1/2" for this purpose (this forty-five degree cut is NOT made at this time).

Rough cut should leave the pencil line.Step 4 begins by tracing the shape of the side profiles on the back (flat) side of each foot. I am careful to account for mirror images of the back feet and the two front corner wrap-around feet assemblies. I number the pieces to get maximum grain matching when the two sets of wrap-around feet are assembled (see the black cherry feet I crafted for a secretary desk and note the grain matching). When I place the stencil on the flat side I position it so that the narrow end of the stencil is up against an end of the stock. The other end is where the forty-five degree cut is made and I want the 1/2" margin on that end. Next I rough cut the profile on the band saw, including the half-round profile (the router can't be used for this or it will produce serious chip out). This cut should leave the pencil marks to provide guides for sanding.

An oscillating sander is used to shape the side profile.Next the profile is sanded with an oscillating sander using 120 grit paper and then hand sand progressing to 180 grit. Note there are parts of the profile that can not be sanded with the oscillating sander. A file, chisel and sandpaper are used to complete those with the exception of the half-round which I leave for later.

Step 5 is to finish the shaping of the half-round. This needs to match the front half-round profile, which was shaped with a router in Step 2, very closely. Failing to shape this correctly will be highly noticeable in the final piece. I use the small block plane to eliminate most of theFront wrap around feet ready for glue up. blade marks and for those blade marks close to the flat I use a rabbet block plane or small shoulder plane because the blade on these planes extend to the edge. A sharp chisel can pare the flat areas smooth. Finally I hand sand to 180 grit. Now I cut the forty-five degree cuts needed to join the front pair of wrap-around feet. I do this on the table saw creeping up to the final cut which will leave the foot 7 1/2" long at its longest point. The feet are now ready for glue up.

Ogee feet are attached to carcass.The ogee feet are attached to the carcass and then trim is applied. The shaped feet are not wrapped around the back. However, a rectangular piece of stock is dovetailed into each ogee foot to absorb side loads when the piece is slid along the floor. The pocket screws are used in lieu of clamps to hold things in place while the glue dries. They add little structural strength.

Trim attached using a sliding dovetail of sorts.Trim runs across the grain over an 18" distance. Simply gluing it in place would eventually result in a weak joint as the sides expand and shrink with seasonal temperature and humidity changes. It may take a number of years but the end result would surely be a broken joint or split wood. Nailing the trim would solve most of the problem but they too eventually fail. A better solution is shown at right.

Bottom of hutch carcass.Here tails are screwed to the top in short sections that are spaced several inches apart. The trim is milled with what might be called two half pins which in turn creates a wedged grove allowing the trim to slide into place. Glue is applied to only the front few inches holding the side trim to the front trim. As the top expands/shrinks it is free to move sliding along the dovetails.

The hutch bottom carcass now looks like the picture at left. Things are shaping up.

Drawer inside with white oak front and birch body.At left is a completed drawer. The front is white oak and the remainder of the drawer is yellow birch. Birch is less expensive than white oak, but dense and hard. It finishes well and runs in color from pale brown to dark reddish-brown.Drawer bottom view. Note the dovetails and tapered bottom.

At right is a bottom view of the drawer. Note the hand cut dovetails. In the front are half-blind dovetails, meaning they only show on the side because of the lipped front. In the back are through dovetails, meaning they can be seen from the side and back. Notice also the tapered bottom. This allows the bottom to more easily expand/shrink with seasonal Base & cupboard carcasses.temperature and humidity changes. The drawer front is 7/8" thick and the rest of the drawer is 1/2" thick (no eighth or quarter inch plywood here). It will take a lot of beating and still last for centuries. This drawer design is ages old and difficult to improve upon.

The cupboard carcass is now glued up, shown here on its maiden voyage on the base. You can see the pins at the ends of the sides, which will receive the tails of the top, and then the remainder of the face frame will be added.

White oak is a dense hardwood. This piece is getting very heavy. I am glad the decision was made to make it in two pieces. Moving it around the shop now requires help from a friend.

Not visible in the picture, but each shelf and base top have a grove routed in them 2" from the back, so that plates and serving trays can be displayed upright.

Hutch base front. Note the grain patterns in the doors.Hutch base side. Note the grain pattern in the drawers.The ship-lapped back for the base was milled from plain sawn red oak stock, which is much cheaper than quartersawn white oak. After applying the lapped back, constructing the doors and shelf, the base was sanded and finished using Waterlox Tung Oil and MinWax Wipe-On-Poly. Because these finishes build slow and thin, and oak soaks them up, I had to apply up to 10 coats. The front view is shown at left. Note the bluish reflections caused by incandescent light bouncing off white walls. The thickness of the finish causes the bluish spectrum to be visible. The grain in the doors are really visible in this view. In the side view at right the reflections are dramatically reduced  and the grain in the drawers is much more visible.

Base top showing the hand sawn dovetails.At left is the base top showing the hand cut dovetails. Look closely (double-click picture for a larger view) and you will see that each dovetail is slightly different size and taper. This actually adds character to the piece. Machined dovetails, with their every-dovetail-is-exactly-the-same look, looks sterile and bland. Also note the scribe line used by the cabinetmaker to know how deep to make the cut. This is intentionally left as another "tool mark" that is a hand-made Hutch base drawer side showing half-blind dovetails and branding.tell-tale sign. If you look at antiques with exposed dovetails you will likely see this scribe line.

Front side drawer dovetails are almost always half-blind meaning they can only be seen from the side and not the front. They are more difficult to make because they require pin sockets (see pin sockets used in the hood of a Shaker Tall Clock). Again the scribe line is visible. The pins and tails are highlighted by the contrast of the white oak and red birch, the latter used for the drawer box. Each drawer is branded using a branding iron with my name. I am hoping that one day 200 years down the road a descendant will wonder about the craftsman who made this piece, and want to know how he is related.

Cupboard without doors.The cupboard has progressed since we last showed it. The top is dovetailed in place, the v-grove ship-lapped back is on and one coat of finish applied to it, a back bottom rail has been added to receive the ship-lapped back via a tongue and grove and the trim is applied.

If you look closely you will see that the v-grove ship-lapped boards are of random width, and though not visible they are also half inch thick. This is traditional for two very practical reasons. First, half inch is strong enough for the back and it saves the additional weight of three quarter inch stock. And second, the backs were usually made from scraps left over that either had too much twist or warp to mill three quarter inch stock but would mill to half inch, and this scrap usually came in random widths. Practicality aside, I think the random widths adds to the character of the piece.

Notice how the oak darkens with the application of a clear tung oil finish, even with one coat. White oak looks rather pinkish prior to any finish but darkens nicely when applied, and the figure pops out, especially the rays, which show up only in quartersawn oak.

Setup used for the cope cut.The doors on this project are true divided light doors. Each light is a single pane of glass and the stiles, rails, mullions and muntins are joined with cope and stick joinery. This is not a task for the feint of heart, either mentally or physically. The number of joints in a single door can seem overwhelming, and milling all parts to the exact dimensions is crucial. Any differences in mullion or muntin length can produce a door that will not go together or one that is not square. In addition there are three tenon lengths to cope with (No pun intended, but it works!). It is very important to have a repeatable procedure for milling these parts. Lastly, these parts are very small and there is ample opportunity for a serious accident, which I want to avoid at all costs.  To that end I use a setup shown at right.

Blocks are used with the shaper fence to set the tenon length.You might ask why I use a shaper to drive a router bit. The answer is that I am using Lonnie Bird's Divided Light Door Set (model number 800.525.11) which is a three bit set. This set has an advantage over single bit sets in that it allows for tenons of any length. The set comes with one bit for cope cuts and another for the stick cut. I don't use the third rabbeting bit because I feel it is too dangerous with pieces this small. I set up the router table for the stick cut, the shaper for the cope cut and the table saw for the rabbet cut. I also set up my dedicated mortiser at this time because it will be used for milling mortises in muntins. Once each machine is meticulously adjusted to give matching joints I leave them undisturbed throughout the process.

The bearing guides the cut along the sled edge.The trick with this divided light set is to get the tenon length correct and to get the tenon correctly registered with the cope profile. I use a sled whose edge rides along the bit's bearing (see picture at right). But to get the correct tenon length the stock needs to hang over the edge of the sled. For this registration I use two blocks of the appropriate thickness sticky taped to my shaper fence. Then I place the edge of the sled against the blocks, push the stock up against the fence and secure it in place (shown above at left). I notch the stock to assist the cope bit from having to remove all the material - it only removes that which defines the cope shape.

Two grips make for a safe cope cut.The stock is 7/8" square, fairly typical for this application. But one problem is that the bearing is too far down from the stock to ride on the sled edge without the use of a spacer, which I attach with sticky tape. I also sticky tape sandpaper to the holding block to prevent the cope bit from pulling the stock into itself and destroying the squareness of the cut.

One critical check is to be absolutely certain that the sled's fence is perpendicular to the sleds edge. If not, again the cope cut will not be square.

Note that I use a sacrificial block to reduce tear out. Tear out in this instance isn't generally a problem because the subsequent stick cut will likely remove any damaged material. But I find this to be good practice anytime there is the potential for tear out. Now I can make a safe and clean cope cut with both hands on the grips and away from the bit (above left).

Rabbet cuts are done on the table saw.Safety is always a consideration in the shop, hence I perform the rabbet cuts on the table saw. I find this much safer than a router cut with such small pieces. The blade is only 5/16" high. I use a feather board and push stick to stay clear of the blade.  The short mullions are a little more dangerous than the longer muntins, but all-in-all the rabbet cuts are relatively easy compared to the sticking cut which comes next.

First sticking cut is less dangerous than the second.The stick cuts for the mullions and muntins are potentially dangerous because the stock is narrow and unstable, especially on the second cut. I use a feather board to hold the stock against the fence as it passes the router bit. This way I can remove my hand from the infeed side and place it on the outfeed side after it has passed the feather board, bypassing the bit altogether (below left).

The second sticking cut is more dangerous.Muntins require a mortise in the middle to allow for mullion tenons to enter from each side. This cut is performed on the dedicated mortiser prior to any of the cope, stick or rabbet cuts. It is critical that this mortise be correct or the cope and stick joints will not seat properly. In addition, they must fit snug along the sides or you risk unsightly gaps that will need to be filled, but still they almost always show upon critical inspection. The mortiser is set up and meticulously adjusted with the other equipment before any work is done on the final material. Like the other three pieces of machinery it is left undisturbed throughout the process. Finished muntins are shown below right. Notice the through mortises in the middle.

Completed muntins.The final door will be a clean seamless matrix of cope and stick joints, the doors will register themselves square, and it will be exceptionally strong thanks to all the mortise and tenon joints involved.

Six Pane Oak Hutch CupboardThe picture at left shows the finished cupboard sitting on its base top. Notice that the door has been designed such that the muntins hide the fixed shelves behind them. The plate is sitting in a grove and leans against the back. All four surfaces (base top, cupboard bottom and two fixed shelves) have this plate groove.

The v-grooved ship-lapped back shows nicely through the divided lights. The spaces separating each board will provide for expansion/contraction that accompanies seasonal temperature and humidity variations. But just as important, the vertical lines add to the overall elegance of the piece. You can visit the Gallery page to see more pictures of the finished piece.
