As a note about the logo above, where as well a "glossary" other terms -- dictionary, lexicon, and thesaurus -- are also mentioned: these terms are not included just for decoration. Instead, as this project becomes more complete, you will see greater concern toward a "conceptual approach" to terms such as "Shaper Cutter", "Router Bit", and "Jointer Knife", "Plane Iron", "Saw Tooth", "Moulding Cutterhead", all terms that -- at bottom -- designate tools possessing a "Cutting Edge", and so forth, but because they have different profiles on their edges, and are contained on different tools -- even though they have the same function -- they are identified by different labels.
Another example to illustrate the "conceptual approach" are the following terms that are parts of Joints: "Tenon", "Biscuit", "Spline", "Tongue". While each is different, at bottom, they perform the same function.
By showing these kinds of relationships among these terms, this glossary will also function as a thesaurus.
Among the sources consulted in constructing this glossary is the Oxford English Dictionary, because it -- alone -- is the dictionary that prides itself in having the "original", i.e., "first" use of a term in the context of a specific meaning. With that understanding, you would think, for example, that the term Trunnion, in it its connotation as the under-structure of a circular saw's Arbor assembly, would be featured in the OED's entry for trunnion. As of 4-2005, this was not true. Thus, in constructing this glossary, necessarily, I had to depend on a variety of sources. All of these sources are listed appropriately as part of the information given for each entry.
Other sources that I will consult regularly are:
(1) Raphael A Salaman's Dictionary of Woodworking Tools, c 1700-1900 and Tools of Allied Trades, Revised edition. London: Unwin, and Newtown, CT: Taunton Press, 1989.
Truly, this work is an amazing piece of scholarship, evidently virtually a life-long pursuit of the primary author, Raphael Salman, but in later parts of the project, many other hands, spread across the globe, made contributions. The bibliography of sources -- overall, between 300 to 350 tiles -- occupies almost 10 pages.
(2) Vic Taylor, Woodworker's Dictionary , Hemel, Hempstead, England: Argus Books,1987; Pownal, VT: Storey Communications, 1990. 260 pages.
The contents of Taylor is largely based on the "Woodworker's dictionary" -- a monthly series in Woodworker Magazine from 1962 to 1970 -- contains what I estimate is 5,000 entries, i.e, definitions and cross-refences. Numerous drawings enhance many entries, but there are no sources cited.
According to its "Introduction", the Woodworker's Dictionary includes "a wider coverage of antique furniture, furniture decoration, and the updating of materials and techniques; ... woodworking terms used in the USA, together with many examples of purely American furniture designs; ..., some French terms are necessarily included because of the enormous influence of French designers and craftsmen, [but] the book is primarily devoted to British and American furniture and woodwork".
Claiming to be "a comprehensive and fully illustrated dictionary of terms relating to all types of woodworking, including cabinetmaking, carpentry, joinery, upholstery, and furniture repair, this is a reasonably cheap -- on bookfinder.com -- home reference for anyone who works with wood. Woodworker's Dictionary covers such workshop practices as making joints, polishing, turning, carving, sharpening tools, and the tools themselves. It also contains information about antique furniture. Two appendices give definitions of well-known designers, craftsmen, and furniture periods".
The book's author, Vic Taylor -- an editor of Woodworker Magazine -- has been associated with woodwork and furniture making throughout his career. During his career in both England and the United States, he has both written and illustrated books on woodworking and articles for woodworking magazines. While I can't find any direct evidence to bear out my hunch, that Charles Harold Hayward had a hand in the origin of this dictionary is, for me, a given, a fact that cofirms my conviction that the book is solid.

(5) Peter C. Welsh Woodworking Tools, 1600-1900 Washington, DC: Smithsonian Institution, 1966 (Contributions from the Museum of History and Technology: Paper 51 Bibliography 227.)
(While the focus of sources 1, 2 and 4 treat only tools of an earlier vintage -- definitely pre-1900 -- these tools remain essential to any history of woodworking.)
(6) Joseph Aronson, The Encyclopedia of Furniture. New York: Crown Publishers, 1938.
Selecting Aronson goes along with my conviction that this history of woodworking should be "document-driven"; that is, as much as is possible, the history of woodworking should speak for itself, especially through documents contemporary to periods that the history covers. During his lifetime, Aronson had a reputation as an authority -- maybe "the" authority -- on furniture history. Extended articles in his Encyclopedia cover "Modern", "England", "France", "Spain", "German", "Spain", "Sweden" and "American" furniture topics, and briefer articles treat, furniture joinery and construction, furniture design and designers, and furniture woods, among other topics. In addition -- and perhaps most significant -- during his lifetime, Aronson himself recognized as a furniture designer in his own right. While his coverage of furniture topics are "broad-brush-stroke", rather than detailed, throughout the Encyclopedia of Furniture, Aronson speaks with the authority of an expert with a command of the subject matter, which is just what I need to guide me in writing entries on furniture periods and other matters associated with any analysis of how -- in their selection of woodworking projects -- woodworkers confronted the construction of furniture.
(7) Harvey Green,Wood: Craft, Culture, History. New York: Penguin, 2006.
Wood: Craft, Culture, History is the first book in my experience that looks at the "culture of wood", or maybe it's "the woodworking culture". Whatever, upon spying it, I realized a heretofore unrecognized truth about amateur woodworking: amateur woodworking is a "culture", similar to a "participatory" sport, like golf or tennis or racquetball, but -- at least in my experience -- has not gotten such recognition. Why? This neglect of observation is obvious, in my view, though, for the following reason: Woodworking is an activity engaged in by "insiders", who are not taken to introspection about their activities, while "outsiders" who may be looking in -- and possess the analytical skills needed to expose woodworking as a culture -- fail to understand the chemistry involved.

(9) the Walt Durbahn "Dictionary of Carpentry Terms", 1947, included in Fundamentals of Carpentry, volume 1. Its usefulness belies by its deceptively slight appearance, it is a source marred only by a misleading title: at least half of its entries relate to woodworking.
(10) Aldren A Watson, Country Furniture. New York: Thomas Y Crowell, 1974. Profusely illustrated with pen drawings by the author, this book -- picked up for next to nothing at a library book sale -- features a twenty page glossary, where most entries include one illustration and a fairly large, very useful bibliography. Coverage is up to late 19th century. Not a how-to-do-it or project book, this book explores the tools and processes of what Watson calls the "country furniture-maker", before the introduction of powered equipment.
(11) and, finally, any other sources that I encounter and that prove useful. The latter I will cite on the spot.
But my intent -- with the assistance of a group of Editorial Advisors -- is to look widely among other sources, especially woodworking manuals, documents contemporary to a particular era, old newspapers, online databases of the 19th century and later, etc., etc.
I am not claiming to be an expert woodworker.
Finally, I want to declare at the outset that I am not an expert at any of the topics discussed in this website -- i.e., "Woodworkinghistory.com". Instead, on the matter of "expert", I can claim to be an expert researcher, that is, "expert" in my skills in exposing what experts about topics covered in the website state or claim about the broad range of woodworking topics.
While I lack academic credentials in lexicography -- the art of dictionary making -- I have dabbled in the field, the primary evidence being my editorship of the set of ten dictionaries of concepts for Greenwood Press.

Treated together with Carpenter, Joiner, Mechanic, Craftsman. Briefly, a Cabinetmaker is a woodworker who makes cabinets and does the finer kind of joiner's work.
Cabinetmakers work in solid wood, typically Hardwood, though Veneers of highly prized wood may be used for decorative purposes. As "finish" carpenters, Carpenters can work at the same level of excellence as cabinetmakers; mostly carpenters engage in the initial stages of construction, activities that lead up to the point where a construction needs finishing touches; for example, finish carpenters takeover where Moldings for ceilings and banisters for stairways are precisely cut and mounted.

According to its moisture content, wood will either emit or absorb moisture from the surrounding air until the moisture in the wood balances with the moisture in the air. When this point is reached, the wood is said to be at equilibrium moisture content (E.M.C.). Since wood is exposed constantly to daily and seasonal changes in the air's relative humidity, the moisture content wood itself makes changes are constant, even if only slightly, but therefore changes in its dimensions. This is the reason doors and drawers often stick during humid weather but work freely the rest of the year.

18. Rules are measuring strips, and are usually made of Boxwood. Their size is expressed by their length in inches or feet, as a "6-inch rule," a " 2-foot rule".
For convenience, using small brass hinges, they are made to fold, -image in goss] and one is said to be "two-fold" when made of two pieces, "four-fold " when made of four, and "six-fold" when made of six pieces. Fig. 28 shows a four-fold rule.
To preserve the rule from wear, the better class are "bound" by a strip of brass which covers each edge : others are "half-bound," having only on edge covered and still others are "unbound," having no edge protection.
Carpenters' rules are usually graduated to eighths of inches on one side, and to sixteenths on the other Besides the regular graduations, other numbers are frequently represented ; but their purpose is so varied that their interpretation cannot be given here.

The unit of power measurement. 1 hp equals 33,000 ft-lb of work per minute. The woodworker is usually more interested in the electrical equivalent of 746 W - 1 hp. As a general guide for circular saws it is generally reckoned that a motor needs '4 hp for each lin (25 mm) depth of cut, though many saws have lower hp. When only thin wood or softwood is being sawn the motor can be of smaller hp.

The other types measures the capacity of a condenser in a high-frequency circuit in which the wood serves as the dielectric material of the condenser.

These are terms applied to the upright and lateral members of a framework, such as a cabinet door. Mostly, stiles run the full length of the door's frame, and rails are fitted between them, usually with mortise and tenon joints. (The space between the stiles and rails is filled in with a panel.) In a door, according to its mode of "hanging", stiles are often often identified according to whether the stile is the "hinge" stile or the "closing" stile.

Briefly, "Table Saw" is frequently also called a "Bench Saw" or a "Contractor's Saw". A Bench Saw, as the name implies -- a Bench Saw comes without legs to support it -- sits on a "Bench" or specially built Table or Bench.

A simpler definition comes from the anatomy of the bandsaw, where two "thrust bearings", one above the table, one below, placed at the back of the blade, prevent the blade from bending as workpieces move from the infeed side to the outfeed of the table. For Resawing operations, ie, making cutting Veneer, especially, where infeed pressure is exceptionally great, the thrust bearing is essential for maintaining the blade's straightness.

Variable-speed motors, in the generally accepted use of the term, are motors where the rate of rotation is adjusted by a controller. The intention of the variable speed function in a tool is safety of the tool's operator. On a Router, for example, an overly large Bit, rotating at 24,000 rpms, is dangerous. However, if the rotation rate is reduced to 10,000 rpms, the chances of an accident that will injure the router's operator is greatly reduced.
