The following is excerpted from “With All the Precision Possible: Roubo on Furniture,” by André-Jacob Roubo, translated by Don Williams, Michele Pietryka-Pagán and Philippe Lafargue. In addition to the translated text and images from the original 18th-centry masterpiece, “With All the Precision Possible: Roubo on Furniture” also includes five contemporary essays on Roubo’s writing by craftsmen Christopher Schwarz, Don Williams, Michael Mascelli, Philippe Lafargue and Jonathan Thornton.
After you have determined the measurements of the work that you wish to make, you draw it on a straight and uniform board. This is what woodworkers call marking the work on the plan. In general, they call the plan all the cuts of the work both in height and width, which represent the shapes [profiles] of all the parts that make it up, or to speak more intelligibly, represent the shape of the wood, its thickness and its width. [It is essentially a layout and cutting list.]
Before beginning to draw the work on the plan, one must determine the width of the sides, the thickness of the wood, the width and the form of the contours, which you do on paper so as to master all the changes or other additions that you judge appropriate. [The implication is clearly that at least some portion of the drawing is at full scale.] This is much better than designing the shapes [profiles] on the plan, because not only are they never as good as on the paper, but because it is lost time that you use to draw the shapes [profiles] at all the places where they are found on this same plan. When the work is of a certain prominence, it is good to make a design of it on paper before laying it out, because you can better make an account of the forms and of the harmony all the parts have with each other.
When the work is particularly considerable, both for its richness as for its size, you must not be content with one design. It is necessary to draw it life-size on the walls of the room in which it will be installed so that you can judge the effect of the entire composition, including both joinery and Carving.
When the nature of the work is out of the ordinary you should make small models of it so as to neglect nothing in making it perfect.
I will not deny that all these precautions are costly, but they accelerate the execution of the work by removing all the difficulties that could be encountered. What’s more, they [the added precautions] respond with success. Whatever experience you have, it often happens that during the execution some difficulties arise that you never thought of. That is why they say to never be too enamored with your theory by avoiding your drawings and models. What’s more, what I recommend here is nothing new, since the greatest Artists of all kinds never execute anything they have not drawn and modeled previously.
The work thus designed or modeled according to the occasion, you draw on the board, which is ordinarily of pine and dressed [trimmed and whitewashed evenly] so as to be able to draw the work neatly. That is why we prefer this wood to all others for this use because when it is of a good quality it is extremely soft and [of] an even hardness throughout.
We use black or red stone, which we call sanguine [reddish drawing chalk], for drawing the work. However, it is good to begin to draw it with chalk because it erases more easily than black or red stone, which you should not use except when you have it all drawn with chalk.
You should not draw the shapes [profiles], as I said above, you must [instead] only do a chamfer/bevel [that is] the width of the moulding, but you must make one edge of the mouldings square while the other is contoured. However, as joinery can be simple, either with moulding part of the frame or moulding exceeding the thickness of the frame, it is good to draw the bulk of the shape [profile] of each type in a different manner, so the worker who makes the work cannot be deceived.
Simple profiles are designed with a single chamfer, like that of side g, Fig. 4. Those where the moulding is part of the thickness of the frame have a small framework [next to] a chamfer similar to the first one, with the exception that it is notched/squared by about a line down from the face corner, like that of side h.
For those of a large framework where the moulding exceeds the thickness of the frame, you make a chamfer in the front, and at the rear you mark their projection on the edges, noting to mark the grooves. When the frameworks have a moulding at the rear, you make a little chamfer to indicate this. Look at profile, side i, which represents a shape [profile] of a moulding projecting on one side, and level with the frame on the other. Side l represents a tongue-and-groove framework where the side enters by tongue and groove into a door frame.
In general, you must take care to draw the work precisely so that whoever makes it can do it more easily and can even trace on [top of] the plan without making other divisions.(4) [In order to design a space’s accouterments such as paneling, windows and doors en toto, one has to divide the expanse of the room into sections to lay out correctly and harmoniously the paneling including the frame work. As the portions of design are assembled into a compiled whole, the risk of compounding any error is substantial. In this passage, Roubo is sternly warning against sloppy layout. When the assembled plan is correct you can then project the same layout onto the wall and cut all your pieces. If the craftsmen doubt the accuracy of the drawing or note an error, they must restart with each portion or restart the layout to fit the wall correctly.] That is why one must trace with a sharpened point all the widths of the frames and the mouldings, which is more accurate than tracing with white stone. One must also take care to mark precisely all the grooves and rabbets, as well as tongues and grooves, the middles as well as the angles, that one must number, so that you can see in a single glance all the parts which go with the others.
The door frames are also marked in bulk, noting only to mark exactly the place of the grooves and the depth of the rabbet. Look at Fig. 5, which represents some paneling marked both in width and height.
The profiles of casements are also marked in bulk. Their little wooden pieces are marked squarely according to their width and thickness. When they are little uprights, you mark them with a cross, which passes the four angles, which indicates their cut with a diamond point. You also draw the rabbet of the frame with glass, as well as the shape of the profile of the imposts [fan lights], those of the door handle/hardware, and of the hand rail, see Fig. 6.
It is good before drawing the work, especially when you have not drawn anything, to calculate all the width of the wood so as to see right away the size of the panels or pilasters that you want to mark, so as to decrease or increase their number.
This way is the surest and easiest, not only because you make mistakes less easily, but also because it shortens the time that you are often required to spend making divisions and erasing them.
Joiners also draw the elevation of their works, especially when it is curved or ornamented with carving. These elevations are made with a sharp point without any shadow, if you omit the ornaments. But the latter are not the work of joiners. These elevations are called plans, in workmen’s terms, and are marked on large panels of pine. As it happens that there are lines which are only for construction, that is to say, to design some joints or some assemblies, you make them of another color than those of the elevation, so as to distinguish them. That is to say, that if the elevation is marked in black, the construction lines are made in red. Sometimes these lines are marked only by a point, especially when it is absolutely necessary that they be perfectly straight.
(4) While I say here that you must draw the work exactly on the plan so that you can trace on top of it, it is good that the workers take the pain to verify if the sections are made correctly when they start to trace so as to avoid following mistakes which may be on the plan, supposing there are any. What’s more, the divisions are always subject to some errors. That is why it is good to re-draw them on the work itself, in spite of the exactness of the plan [replicating the layout on the workpiece].
In an effort to not lose more money on posters, we offer this full-resolution 11″ x 17″ image of A.J. Roubo’s famous Plate 11 for free. Download it, take the file to your local print shop and get it printed on a large-format printer.
The file is a jpg and is in full color. Print it out in color, and the background will resemble the rag paper used for the 1777 original. And the ink will be the dark dark brown found on the original.
If you are worried that the dude at the print shop will claim you need copyright clearance (for an image from 1777…?), print out this blog entry and take it along to the store.
“Hi. We (Lost Art Press) own the original of this image. The person holding this blog entry is allowed to print the image for their personal use. Thank you, print shop person.”
Why are we doing this? Several readers have asked for a Plate 11 poster. Instead of flushing away several hundred American dollars down the American Standard (and ending up with hundreds of unsold posters in my cellar), we decided to give the electronic image away (and use the money we saved for moss research).
I never get tired of this particular plate. It is so blinking odd. The scale of the jigs, tools and work hung on the walls of the workshop bear no connection to reality. The brace on the wall is the same size as one of the workers. However, if you own the “Book of Plates” you can play a fun game. All of the objects shown on the walls of Plate 11 are actually things found in other plates in the book.
I’m sure you could make it into a drinking game. Somehow.
The Crucible Planing Stops will go up for sale on Monday in our store. The stops will be $49 plus shipping (I’m afraid they are unlikely to arrive at your address before Christmas).
These planing stops represent two years of work and almost a $50,000 investment in patterns, matchplates and ductile iron. This is our biggest-ever tool run, and we are holding our breath a little bit about how they will fare in the marketplace.
The idea for these cast-iron stops came to me while writing “The Anarchist’s Workbench.” We have had great success with our ductile iron holdfasts, and it occurred to me: why not make planing stops out of ductile?
These stops are less expensive than a blacksmith-made stop, and they are quite easy to install. I’ve made a short video that shows the process here:
The stop is based on the planing stops shown in A.J. Roubo’s masterwork, with some minor tweaks. The stop’s teeth sweep slightly upward, instead of being parallel to the benchtop. This makes it much less likely that a handplane will collide with the stop.
Also, the teeth come sharp – but not too sharp. Beginners can get used to using the stop. Then, when they are comfortable, they can grind or file the teeth so they are needle-sharp, which is how I like mine.
Once we get our first volley of planing stops out the door, we will offer these to our retailers around the world. It is my dearest hope that somehow, someday, one of these stops makes it onto a Roubo-style workbench in Paris – completing a 240-year cycle.
The different Compositions of Dyes appropriate for dyeing Woods, and how to use them
The tinting [dyeing or staining] of woods is of great importance for cabinetmakers, because it is with its help that one can give to woods the different colors, which are necessary for representing all sorts of objects, such as fruits, flowers, animals, etc. However, cabinetmakers always make a great secret of the composition of their dyes in order to preserve exclusivity, and not to increase the number of workers in their trade. From that circumstance comes the fact that most of the compositions that the ancient cabinetmakers used have not been passed on to us, or are presently badly imitated. Those being used presently are defective, or even if they are good, cannot be perfected given that those who possess them hide the process. They keep this information secret not only from their colleagues but even from those for whom the theory could be useful in perfecting the composition of their dyes. This would be much more advantageous than the enjoyment of maintaining a secret, which is not a big thing, but which, even when it is perfectly well known to us, leaves us still to regret the loss of the method of Jean de Veronne, who tinted woods with boiling dyes and oils that penetrated them. This would be a very helpful thing to know, the research of which would be a worthy undertaking for some of our scholars. It is highly wished that one could find the means to use the chemicals having a good tint in the dyeing of woods, because their colors would be more durable. Sadly, the colored parts of most of these chemicals are too thick to penetrate the interior of woods, which is absolutely necessary, so that when working with tinted woods they are all found to be of uniform color throughout their entire thickness and the surface.
That is why in the description of the woods, without the means to which I would like to know the procedure to accomplish the perfect tint, I will explain only ordinary procedures to cabinetmakers, to which I will add some of my own experiences, which is still a long ways from attaining the perfection of which this part can be capable.
The five primitive colors are, as I said above, blue, yellow, red, taupe [brown] and black. Each of these colors is given by different chemicals, which, when mixed together, give the second or composite colors.
The blue appropriate for tinting woods is made with indigo, diluted in oil of vitriol [also known as sulfuric acid], and then put in a sufficient quantity of water.
Yellow is made with barberry, yellow earth and saffron mixed together, or even simply from gaude [this plant, Reseda luteola, is known as weld].
Red is made from the boiling of wool, or even a concoction of Brasilwood mixed with alum.
Taupe is made with walnut husk.
Black is made with the wood of the Indies, the gall nuts and iron sulfate.
Before entering into the detail of the composition of different stains, I am going to give a general idea of the chemicals of which they are composed, so that the cabinetmakers may be less subject to being fooled when they buy them.
Indigo is a type of ash of a deep blue, provided by the leaves of a plant that grows in the Americas and Indostan, and which they sell in little pieces. For it to be good, it must be medium-hard, so that it floats on water, so it is inflammable and of a beautiful blue or deep violet color. Its interior should be strewn with little silver-colored spangles, and appear reddish when rubbed with a fingernail. Indigo is preferred over all other chemicals for staining woods because it is a powder of extremely fine and granular pieces, which are easily introduced into the pores of the woods.
Oil of vitriol or sulfuric acid is the final spirit that one gets from vitriol. This acidic liquor should be very concentrated and be absolutely free of all aqueous parts to be of a beautiful blue color, as I will speak more of later.
Barberry is a little bush of which the fruits, and the bark of the roots are stained in yellow. That from Candie [island off the coast of Crete] has a very yellow wood, and passes for the best.
Woad [this cannot be woad that produces a blue dye] is a rather common plant in France. One boils it in water to extract a yellow liquid, which mixed with a bit of alum, tints very well. Dyers prefer that one, which is the most spare [meaning thinnest] and of a rosy color.
One also dyes in yellow with the yellow wood of which I spoke above page 777. Yellow earth is nothing other than yellow ochre, used by painters.
Saffron is a plant that grows in France, especially in Gatinois [western part of France]. It is the pistil of the saffron flower, which gives these little reddish filaments, or better said, orange, which they sell under the name of saffron, which gives a dye of a golden yellow. For saffron to be good, it should be fresh, of a pungent odor, of a brilliant color and when touched it should seem oily and should stick to the hands.
Alum is a fossil salt and mineral, which is used much in dyeing, whether to set up the materials to be stained or whether for fixing the colors [as a mordant], which it retains all the particles by its astrin-gent quality. The best is that of Rome, which is white in color, and is transparent, a bit like crystal.
Liquor decanted from boiled wool is sold by the wool merchants. In boiling this wool, one gets a decoction of the color rose, which is more or less deep, according to how much water is used to scour the wool, proportional with its quantity.
I spoke up above of Brasilwood, page 771. I will content myself to say here that the decoction of this wood gives off a clear red color, tending toward the orange, and that one deepens its color by adding a bit of alum. Brasilwood from Fernambouc is the best, and they sell it all chopped up at the spice merchants, who sell it by the pound.
The husk of walnuts is nothing more than the first wrapping of these nuts, which one takes off before they are perfectly mature, and which one boils in water to extract a brownish or taupey tint.
Indian Wood, of which I spoke on page 777, gives off a concoction of a deep red, which one stains in black, and when one mixes with alum it stains in violet.
Nut gall is a type of excretion that is found on the tender shoots of a type of oak named “Rouvre.” The most highly esteemed nut gall comes from the Levant [the name given to the countries on the eastern coast of the Mediterranean]. The best ones are those that are the heaviest, and where the surface is thorny. There are both green and black ones, both of which work equally to stain in black.
Ferrous sulfate is a type of vitriol that is found in copper mines. It is the most powerful of the acids, it corrodes iron and copper, and it etches the soft parts with an infinite number of small holes, into which the dye is introduced. Ferrous sulfate is also named Roman vitriol or English vitriol, according to whether it comes from one or the other countries. We make some in France that is, they say, as good as the others. The color of ferrous sulfate [known also as green vitriol] is of a light green: it should be neat and shiny.
Verdigris also works well as a wood dye. It is the green rust scraped from copper sheets. For it to be good, it should be dry, pure, of a deep green and filled with white spots.
There you have a bit of a description of the ingredients commonly used for staining/dyeing woods. All that remains is to give the manner of making use of them.
The Way of Staining Wood Blue
The preparation of blue with indigo and oil of vitriol [sulfuric acid] is done in two ways, namely, hot and cold. Blue for wood is prepared cold in the following manner:
you take 4 ounces of oil of vitriol of the best quality, that is to say, that it is deprived of all aqueous parts, which you pour into a pint-size bottle, with 1 ounce of indigo reduced to a very fine powder. Then you fill the bottle with water, at least nearly so, and you bottle it very carefully, and you seal the cork with wax. you let it infuse for five to six weeks, at the end of which you can use this stain that will be more or less strong, by putting in as much water as you judge appropriate, always ob-serving to add a bit of oil of vitriol, so the dye will be fixed better. When the dye is to the degree of strength that you need, you put it in a stoneware or glazed earthenware vessel, and you soak the wood in it until it is totally penetrated, which sometimes requires 15 days and even one month of time, according to the hardness and thickness of the wood. The wood can hardly have a thickness of more than one line [1/12″].
Cabinetmakers ordinarily use a stoneware butter pot for putting the wood into the dye, which is very convenient because the shape of this vase enables one to put in rather large pieces, without the need of having a very great quantity of dye.
It is very easy to know when the interior of the wood is penetrated, given that you only have to cut a small piece of the wood about 2 to 3 lines from its end. When the pieces that you want to dye cannot be cut like this, you put with them another piece of the same quality, with which you test the degree of penetration of the other pieces.
The Way of Dyeing in Yellow
Cabinetmakers tint in yellow with barberry, with yellow earth and with saffron, which they boil together. This being done, they soak the wood pieces until they are totally stained. The proportion of these chemicals is 2 liters [in this case the French word refers to “litron,” which is about 79 percent of a modern liter, so 2 modern liters is a much larger quantity] of barberry, 6 “sols” [a French penny] of yellow earth, and 4 “sols” of saffron.
A concoction of woad gives a very beautiful yellow of a good tint, and you soak the wood as normal. When this concoction is added to a bit of verdigris, you have a sulfurous yellow color. Saffron infused in grain alcohol gives a very beautiful golden yellow.
The Way to Dye in Red
Red is normally made with brasilwood, which one boils with 6 sols of alum for each pound of wood. This red is a false tint because it is more orange than red. you can substitute the boiling-liqueur from wool, which gives a very beautiful red, leaning toward rose, which one makes deeper by passing the pieces that you have stained into the liqueur of the mixture of Brasilwood mixed with alum. This makes a very beautiful red, more or less deep, depending on whether you leave the pieces of wood more or less a long time in the dye bath of Brasilwood.
Dyeing with decanting liqueur is done very easily. One only needs to boil some wool dyed to this effect, just until it makes a beautiful red concoction. Avoid boiling too much, because the wool will take back the color that it discharged at first.
The proportion of the liquor of wool to be decanted is 1 pound to 4 pints of water for the first decanting, to which one can add a second, even a third, until the wool renders no more color. The concoction of Brasilwood without alum gives a yellowish red, which is sometimes attractive, and is named “Capucine.”
The concoction of Indian Wood is very red, but it makes a blackish stain, which makes a very beautiful violet when mixed with alum from Rome, as I will speak of it later.
How to Dye Taupe [Brown], Black and Grey
Taupe dye is made with a concoction of walnut husk, which can be more or less strong, as you judge appropriate, always adding to it a bit of alum.
An attractive black is made by staining the wood first in a concoction of wood of India (or Campeachy, which is the same thing). When this first application is dry, you dip the wood in a concoction of gall nut in which you have put some ferrous sulfate, or vitriol of Rome. Sometimes one only makes a single dye of these various ingredients, of which the proportion should be 1 part nut gall, 1 part vitriol and 6 parts of Campeachy, all boiled together, into which you dip the wood until it is penetrated.
A grey tint is made with a concoction of nut gall, into which you dissolve some green vitriol [ferrous sulfate] in smaller quantity than for the black stain. The more ferrous sulfate-cuprous there is, the deeper grey it will be. The normal proportion is one part of ferrous sulfate for two parts of nut gall.
The Way to Tint Composite Colors
The ordinary green stain of cabinetmakers is made with the same ingredients as for the blue, to which is added the barberry in more or less quantity, according to whether the green should be more or less deep.
One can make a very beautiful apple green in staining first the wood in ordinary blue, and then dipping it in a concoction of woad, and that with more or less time according to whether one wants to have a green more or less strong.
Violet is made with a concoction of Campeachy, to which one has mixed some alum from Rome. One can have violet more or less deep by staining first the woods in rose and then in the blue, which will give a clear violet.
If, on the contrary, one wishes to have a brown-red leaning toward violet, one stains the wood first in the concoction of Brasilwood, then in that of the Campeachy.
One can obtain composite dye of all nuances imaginable by tinting the wood in a primary color then in another one more or less dark, so that the stain that results from these two colors reflects more or less of each other. This is very possible to do because one is the master to strengthen or weaken the primary colors as one judges appropriate, whether by reason of what the form of the object re-quires, or even by reason of the different quality of wood, which takes the dye more or less well, or strengthens or weakens the color. This has to be highly considered, and it requires much attention and experience on the part of cabinetmakers.
In general, all the dyes of which I just spoke are applied in cold baths. It is not that many of them cannot be used hot, but it is that because it takes a considerable amount of time for the same dye to penetrate into the interior of wood, it is not possible to use them hot. What’s more, cold dyed wood has much more vibrancy than when used with a hot bath.
There it is, a bit of the details of staining [dyeing] wood, at least those that most cabinetmakers use, or which I myself have employed in the attempts that I have made. These have succeeded rather well, but they have not been followed by a long enough time to be assured of the success of my at-tempts. It would be highly wished that those who are currently making use of these dyes, or who will be using them later, apply themselves to perfect them which, I believe, is not absolutely impossible. Having done this, they would be rather good citizens to not make a mystery of their discoveries, but only succeed by rendering them public.
Cabinetmakers dye not only their woods for veneer to use them in the place of the natural color of the woods. They also use these same dyes to accentuate various parts of their works while they are being worked. As such, these dyes, like the red of Brasilwood, the violet of the Campeachy, the black, etc., are used hot, which is very easy to do because it is sufficient for only the exterior of the woods being dyed. Other than these dyes, woodworkers in furniture sometimes use a type of yellow color for bedsteads, which is composed of yellow ochre and common varnish, or of this same ochre and the very clear English glue, sometimes they even put it in only water, which is of little use.
Before finishing the dyeing of wood, I believe I ought to give a least-costly method of dyeing white wood red, which is done in the following manner:
you take some horse dung, which you put in a bucket of which the bottom is pierced with many holes, and you place it above another bucket, into which falls the water from the dung, as it gradually rots. When it does not rot fast enough, you water it from time to time with some horse urine, which helps a lot and at the same time gives a red water, which not only stains the surface of the wood, but penetrates the interior 3 to 4 lines deep. In staining the wood with this dye, one must take care that all the pieces be of the same species, and about equal in density if one wishes that they be of equal color throughout. This observation is general for all water-based stains, which have no palpable thickness nor even appearance [they leave no residue or any evident change in appearance], which requires the cabinetmaker to make a choice of wood of equal color and a density as I mentioned before. This demands a lot of experience and attention on the part of the cabinetmakers. And with the exception of the way to compose and use dyes, it is hardly possible to give theoretical rules on this part, for which success is not often due to anything but experience, which is not acquired except with a lot of time, attention and work.
For the fashioning of raw timbers, we understand the manner of splitting [hewing or sawing] and squaring them, which is done in different ways, according to the nature, the quality and the thickness of the wood. They are sawn by the mills, or even by hand, by workers called long sawyers or simply sawyers. I will not speak here of the harvesting of the woods in the forests. I will be content to say only that they are sawn and cut in sizes and lengths relative to our different needs, and that wood thus prepared is called wood samples.
They are found abundantly in all types and all qualities possible in the inventories of the wood Merchants, which they ordinarily cut for themselves and for their clients, and are transported to their storage lots or shops in Paris. [Suppose you go to a lumberyard and in the lumber section you will find 2×4, 2×8, 2×6 etc. This is what is called bois díechantillons. In this case it is oak, pine, walnut etc. of various types but standard dimensions.]
Cut or squared-up woods take different names according to their sizes, and according to the place which they occupy in the body of the tree: We call them dosses [slabs], countre dosses, swinging doors, framework, chevrons and finally planks and battens. Slabs are the first cuts removed from a log in order to square it up, after having removed the bark, like those on sides g–g, Fig. 5 and 6.
When the diameter of the tree is considerable, and you fear that the first cut slab will become too thick, you make a double-cut, which is called a contre-dosse; that is to say, that it is between the first cut dosse [slab] and cut line and the heartwood [wood between the pith and the sapwood] like those on sides h–h, Fig. 6. When the wood is beautiful, the contre-dosse are very soft, being very close to the edges of the tree [closer to the sapwood layer]. They do not have any sapwood except at their extremities, instead of the first cuts, dosse, that have sapwood all over their convex areas. The thickness of the contre-dosse is not precise. It varies from 2 to 4 thumbs. After a log is thus squared, you saw it into thin panels or lumber planks, according to its hardness or softness. You can then judge whether it is appropriate for one or the other. [That is,] [u]nless one cuts planks from the entire width of the tree, especially with soft wood, which I will speak of later.
The double doors of main entrances are ordinarily 12, 15 or even 18 feet long, by 1 foot or 15 thumbs wide, for the longest, and by 4–5 thumbs thick. They are almost always of a hard-quality wood. They should have neither knots nor splits. This may be found in the woods of Vosge, but they are very expensive and very rare.
Lumber for framing is of a length from 6, 9, 12 and 15 feet. They are 6 thumbs wide by 3 thumbs thick. Rafters have the same length as framing, and sometimes more, by 3 to 4 thumbs squared, that is to say, they have as much thickness as their width.
Planks have 6, 9, 12, 15 and even 18 feet of length, by 1 thumb 15 lines, 1–thumb-and-a-half, one thumb-9 lines, and 2 thumbs thickness.
There are also planks of 7 feet length, but they are rarer than the others, and are difficult to find in all thicknesses. With regards to the width of planks of French wood, they vary from 9 thumbs up to 1 foot. However, those of 1–and-one-half thumbs to 2 thumbs are ordinarily a foot wide, and those below this thickness from 9 up to 10 or 11 thumbs at the most.
There is still another type of thin French oak wood, named Entrevoux, which only has but 9–10 lines of thickness, by 6, 7 or 9 feet in length, which is appropriate for making panels, provided that it is soft and beautiful.
For the wood from Vosge, there are all kinds of lengths and thickness of which I spoke above, except that there are none of 6–7 feet, or even less. There are also those of 3 thumbs thickness by 12 feet in length. With regards to its width, that is not fixed, because in all the different lengths and thicknesses of this wood, there are from 6–7 thumbs of width up to 18, 20 and even 26 to 30 thumbs [width]. That is why Merchants do not sell this wood by measurement [of the individual boards], as with the others, but by each row of the lumber stack, which is 4 feet in width.
To facilitate the understanding of widths and thickness of woods for joinery relative to their different lengths, I have attached a table [on the next page] where all the wood types are distinguished according to their length, width and thicknesses.
The wood from Holland is not included in the number of those I have mentioned here because it is only a thin wood, which is sold by the handful or even by the cord. These lengths are of 6, 7, 9 or 12 feet by a thickness of 6 or 9 lines.
The thickest of these woods is called three quarters, because it should have 9 lines thickness, although often it only has 7 or 8 at the most. (The thinner ones are called feuillet [leaf] and are only 4 to 5 lines thick, while it should be 6 lines thick.)
It is to be noted that French wood is always thicker than the wood from Vosge with each sample; that is to say, that the first always has 2–3 lines more than its thickness, such that the wood of 1 thumb sometimes has 14–15 lines [thickness]. On the contrary, the latter [wood] always has 1 line less than it should have, which is a shortcoming. Also it has the advantage of being straighter than the other, and has less waste.
For the battens made of oak, wood Merchants sell them only rarely. Joiners use wood from Holland for thin panels, and they even saw [resaw] them at their shops while on edge, to the thickness and of the quality that they judge to be appropriate.
Pine is not subject to the rules of thickness of which I just spoke, at least that type used in the woodworking of buildings.
That from Auvergne ordinarily is 12 feet in length by 14–15 lines in thickness. Its width varies from 10 to 14–15 thumbs.
That from Lorraine has only 11 feet in length at the most. Its thickness is the same as that from Auvergne, but the most ordinary thickness is from 10–12 lines. Its width varies thus, from that of the latter.
There are also the little leaves of pine from Lorraine, of the same length as the planks, which have from 6 up to 8 lines thickness.
Walnut and elm are not found cut into planks like the other woods. Whenever Joiners have enough money, they buy whole logs which they cut themselves, namely the elm, into slabs of 5 thumbs’ thickness, and the walnut into slabs of 3 thumbs [thickness]. They still saw black walnut to make the panels for tables of 4 lines thickness, which have a width of the whole log, which is sometimes 2–2.5 feet in width.
Beech is found cut into planks of 15–18 lines, and even 2 thumbs thickness by 7, 9 and 12 feet in length. They also sell slabs of this wood for making woodworking benches, tables for the kitchen, and butcher tables, tables that have a length from 7–12, and even 15 feet, by 18–30 thumbs in width, and 5–6 thumbs’ thickness.
Although the wood which one chooses has by itself all the required qualities, it is still necessary to watch out for its preservation. Because wood for joinery should not be used except very dry, it is of the final consequence to Joiners to always be well provisioned with wood of all types, which they keep and dry in their yard before using them.
They should also take care that their yard not be placed too low, nor planted with grass, because the falling and gathering of leaves will prevent the run off of water, which could ruin the wood pile coverings and also the base of a woodpile.
The terrain occupied by the woodpiles should be higher than the rest of the yard, so that water does not collect there. It must be well set up and leveled, after which you put on top some pieces of wood side A, which we call chantier [beam/timber spacers] which has a length the same as the width of the pile – ordinarily 4 feet, although sometimes they make them wider. You make them the greatest thickness possible, so that they make the pile taller with the most possible space between the boards.
You put the spacers distant from each other about 3 feet. Their topsides should be squared and straight, after which you pile the wood on top, after having taken the precaution of putting the worst planks on the lowest level to save the better woods from ground moisture. You make the piles in two ways, according to whether the wood is being dried or is already dry. In the first case, you pile them up to see through, which is done in the following two ways:
The first is to place the planks side by side with a space [between them] about equal to two-thirds of their width, and to separate each row of planks by laths [stickers] f–f, which separates them, prevents them from touching and maintains them in a solid position on top of each other, such that one can stack up the piles up to 20–25 feet in height. (Fig. 1).
The second way to make see-through piles is to make them squarely; that is to say, to give them as much width as the planks are long. You first put a row of planks spaced equally, as in the first way, always such that the width of the row of planks and the additional space between them is equal to their length.
After this, you put on top some planks in another row, in the same order and at a right angle, which means that you have no need for stickers/spacers, and that the planks have more air between them. However, you should not leave them thus piled for a long time, for fear that the wood will rot where the pieces sit on top of each other. (Fig. 2.)
Rafters of 6–9 feet are piled in this fashion, without however being see-through.
The way to pile seasoned wood does not differ from the first of these two ways, except that the planks touch each other side by side, instead of being see-through. You separate each row with some spacers which you put at an equal distance to that of the chantiers which are three feet apart, so that the planks are always straight and do not warp. However, this last term signifies more of a hollowed-out plank along its width [cupping] than a warping [bowing].
The top of the pile is covered with planks positioned to overlap one on top of the other; one of the ends of which is positioned on another plank (side a, Fig. 4) which is called l’egout de la couverture [not quite like a gutter but more like a rain diverter] and which lies flat upon the pile. One should note, however, that it overhangs the front of the pile by 3 or 4 thumbs, and that it slopes a bit to the outside, in order to facilitate the runoff of any water. You raise it up a bit at the back to create this effect. The other end of the planks of the cover hold a piece of wood b, which is named chevet [or riser], which is positioned on edge on two pieces of wood c, in which a notch is placed, and which is stopped with wedges d, in order that it not turn. The chevet should be a foot and a half tall at least, so that the water accumulates less on the piles.
The middle of the covering should be supported by a piece of wood e, which is placed above the pile, and the two planks along the sides rs, rs should be wider by 3 or 4 thumbs than the two sides of the pile, so that the water does not fall back along its length.
When you wish to make the piles more than 4 feet thickness, you should take care to put the spacers in concert (that is, you place them such that the total length of two spacers is more than 4 feet, which is the length of the laths), overlapping such that it maintains the solidity of the pile. You will need to take care to keep everything straight and vertical in all directions, so as to avoid accidents that its fall might cause.
For thin wood, like the wood from Holland, the battens of oak and of pine, the custom is not to pile them in the open air in the middle of the yard, but to pile them under sheds and above the shop where the workers work, the reason being, they say, that they are preserved better. I believe, in spite of this practice, that they would be better in the yard, where they will receive the air from all sides, and where they will not be exposed to insects [powder-post beetles etc.].
As to their preservation, I believe they run no danger being out in the air. The piles of wood from Holland, which reside for a long time in the wood lots of the Port of Hopital and of Rapee without any damage, are surely guarantees of the truth of what I advance here.
What I am saying here is only general. I know perfectly well that all woodworkers cannot have
great wood yards nor large provisions of wood. But still, for reasons of economy, they should always do their best to be well prepared with samples, and to watch over their preservation as best as they can, so as not to be obliged to have to buy some from the Merchants. The wood that they sell is almost never dry, and the woodworker will pay dearly for what the wood Merchants have.
The more wood is hard, the more time it takes to dry. That is why one should not reasonably use wood that has not been cut at least 8 years in order to be able to do good work. It is not necessary, however, that it be too dry, especially for pieces of joinery, where the wood has no more sap and where the humidity is totally expunged: this cannot be appropriate. [Once the sap no longer is flowing from the lumber and the moisture has departed there is no need to season the lumber any further.]
