“Mechanic’s Companion” is one of the foundational English-language texts in woodworking and the building trades. First published in 1812, “Mechanic’s Companion” is an invaluable and thorough treatment of techniques, with 40 plates that provide an excellent and detailed look at the tools of the time, along with a straightforward chapter on the geometry instruction necessary to the building trades.
If you work with hand tools, you will find useful primary-source information on how to use the tools at the bench. That’s because Nicholson – unlike other technical writers of the time – was a trained cabinetmaker, who later became an architect, prolific author and teacher. So he writes (and writes well) with the authority of experience and clarity on all things carpentry and joinery. For the other trades covered – bricklaying, masonry, slating, plastering, painting, smithing and turning – he relies on masters for solid information and relays it in easy-to-understand prose.
Having now mentioned the principal tools, and their application, it will here be proper to say something of the operations of Carpentry, which may be considered under two general heads; one of individual pieces, the other the combination of two or more pieces. Individual pieces undergo various operations as sawing, planing, rebating, and grooving, or ploughing: the operation of the pit saw is so well known as hardly to need a description; planing, rebating, grooving, or ploughing, are more frequently employed in Joinery, and will be there fully described. The other general head may be sub-divided into two others, viz. that of joining one piece of timber to another, in order to make one, two, or four angles, the other that of fastening two or more pieces together, in order to form one piece, which could not be got sufficiently large or long in a single piece; there are two methods of joining pieces at an angle, one by notching, the other by mortise and tenon…
Fig. 1 the manner of cocking tie beams with the wall plates fitted together. See § 25.
Fig. 2 shows the manner by which the cocking joint is fitted together, No. 1 part of the end of the tie beam, with the notch to receive the part between the notches in No. 2, which is a part of the wall plate. See § 25.
Fig. 3 dove-tail cocking; No. 1 the male or exterior dove-tail cut out on the end of the tie beam: No. 2 the female or interior dove-tail cut out of the wall plate, to receive the male dove-tail. See § 24.
Fig. 4 the manner of joining two pieces together to form a right angle, so that each piece will only be extended on one side of the other, by halving the pieces together, or taking a notch out of each, half the thickness. See § 26.
Fig. 5 two pieces joined together, forming four right angles, when one piece only exceeds the breadth of the other by a very short distance: No. 2 the socket of one piece, which receives the neck or substance of the other. This and the preceding are both employed in joining wall plates at the angle; but the latter is preferable, when the thickness of walls will admit of it.
Fig. 6 the method of fixing angle tics: No. 1 part of angle tie, with part of the wall plate: No. 2 the wall plate, showing the socket or female dove-tail. Though the angle tie is here shown flush with the wall, in order to show the manner of connecting the two pieces together; the angle tie is seldom, or never let down flush, as this would not only weaken the angle tie, but also the plate into which it is framed. See § 27.
Moulding machine. The waving engine is a moulding machine that operates off a pattern-cutting principle. The flame mouldings it makes are uncommon today and not generally made with common workshop machinery.
The following is excerpted from “The Art of Joinery,” the first book published by Lost Art Press. It was out of print and unavailable for several years until we released this revised edition in the fall of 2013. It contains:The lightly edited text of Joseph Moxon’s landmark work on joinery – the first English-language text on the topic; modern commentary on every one of Moxon’s sections on tools and techniques by Christopher Schwarz; the original plates; and more.
And later this year, we’ll be offering a beautiful hardcover reprint – with a new introduction by Chris – of all of “Mechanick Exercises or the Doctrine of Handy-Works,” which also includes smithing, carpentry, turning and brick laying (Peter Nicholson’s “Mechanic’s Companion” was an early 19th-century update to Moxon’s early 18th-century work). This important early woodworking book deserves to be in print at a price everyone can afford (about $25 for a clothbound book with sewn signatures). Plus every book sold will help benefit the Early American Industries Association, which assisted with book production.
The waving engine described in plate 5. fig. 7, hath A B, a long square plank of about seven inches broad, five foot long, and an inch and a half thick. All along the length of this plank on the middle between the two sides runs a rabbet [a raised track], as part of it is seen at C. Upon this rabbet rides a block with a groove in its underside. This block is about three inches square and ten inches long, having near the hinder end of it a wooden handle going through it [that is] about one inch diameter, as D E. At the fore-end of this block is fastened a vise, [that is] somewhat larger than a great hand-vise, as at F. The groove in the block is made to receive the rabbet on the plank.
At the farther end of the plank is erected a square strong piece of wood, about six inches high, and five inches square, as G. This square piece has a square wide mortise in it on the top, as at H. Upon the top of this square piece is a strong square flat iron collar, somewhat loosely fitted on, having two male screws fitted into two female screws, to screw against that part of the wooden piece un-mortised at the top, marked L, that it may draw the iron collar hard against the iron [that cuts the moulding], marked Q, and keep it stiff against the fore-side of the un-mortised piece, marked L, when the piece Q is set to its convenient height. And on the other side the square wooden piece is fitted another iron screw, having to the end of its shank fastened a round iron plate which lies within the hollow of this wooden piece, and therefore cannot in draft be seen in its proper place. But I have described it apart, as at M. {Fig. 9.} Its nut is placed at M on the wooden piece. On the farther side of the wooden piece is fitted a wooden screw called a knob, as at N. Through the farther and hither side of the square wooden piece is fitted a flat piece of iron, about three quarters of an inch broad and one quarter of an inch thick, standing on edge upon the plank; but its upper edge is filed round {the reason you will find by and by}. Its hither end comes through the wooden piece, as at O, and its farther end on the opposite side of the wooden piece.
Upright in the hollow square of the wooden piece stands an iron, as at Q, whose lower end is cut into the form of the moulding you intend your work shall have.
In the fore side of this wooden piece is [a] square hole, as at R, called the mouth.
To this engine belongs a thin flat piece of hard wood, about an inch and a quarter broad and as long as the rabbet. It is disjunct [distinct, unconnected] from the engine, and in fig. 8. is marked S S, called the rack. It hath its under[side] flat cut into those fashioned waves you intend your work shall have. The hollow of these waves are made to comply with the round edge of [the] flat plate of iron marked O {described before}. For when one end of the riglet [workpiece] you wave is, with the vise, screwed to the plain side of the rack, and the other end put through the mouth of the wooden piece, as at T T, so as the hollow of the wave on the underside of the rack may lie upon the round edge of the flat iron plate set on edge, as at O, and the iron Q, is strong fitted down upon the reglet [sic]. Then if you lay hold of the handles of the block D E and strongly draw them, the rack and the riglet will both together slide through the mouth of the wooden piece. And as the rounds of [the] rack ride over the round edge of the flat iron, the rack and reglet will mount up to the iron Q, and as the rounds of the waves on the underside of the rack slides off the iron on edge, the rack and reglet will sink, and so in a progression (or more) the riglet will on its upper side receive the form of the several waves on the underside of the rack, and also the form or moulding that is on the edge of the bottom of the iron. And so at once the riglet will be both moulded and waved.
But before you draw the rack through the engine, you must consider the office of the knob N, and the office of the iron screw M. For by them the rack is screwed evenly under the iron Q. And you must be careful that the groove of the block flip not off the rabbet on the plank. For by these screws, and the rabbet and groove, your work will be evenly gauged all the way (as I said before) under the edge of the iron Q, and keep it from sliding either to the right or left hand, as you draw it through the engine.
Analysis Of course, the No. 1 question you have to have about the “waving engine” entry is what the heck the thing actually does. Is it a planer? A moulding machine? Well, yes. It works like both a planer and a moulding machine to produce what are called rippled or waveform mouldings, which were all the rage during Cromwell’s reign in England.
Wave mouldings show up in many picture frames of the era and reflect light in a most unusual way – thanks to their undulations or ripples.
Moxon’s device seems complex from the description because he is writing about a thing that doesn’t exist in this exact form today. In essence, the waving engine produces rippled mouldings much like a duplicator lathe or a pattern-cutting bit in a router. A flat piece of iron follows a block with the desired pattern cut into it. This moves the stock against a fixed cutter, which gradually (very gradually) cuts away the waste to reveal the final wave shape in the workpiece.
The workpiece, by the way, is pulled through the waving engine by hand. If you are interested in this fascinating machine, I recommend you check out a 2002 article by Jonathan Thornton, who built a close reproduction of Moxon’s waving engine and shows how it developed into a fancier machine that worked with a crank.

45. Of Saws in general. Pl. 13. Fig. 6, 7, 8, 9, 13.
A saw is a thin plate of steel indented on the edge for cutting, by a reciprocal change in the direction of motion, pushing it from. and drawing it towards you. The cut which it makes, or the part taken away in a board, is a thin slice, contained between parallel planes, or a deep narrow groove of equal thickness. Saws are of several kinds, as the ripping saw, the half ripper, the hand saw, the panel saw, the tenon saw, the sash saw, the dove-tail saw, the compass saw, and the key-hole or turning saw. The teeth of these saws are all formed so as to contain an angle of sixty degrees, both external and internal angles, and incline more or less forward as the saw is made to cut transverse to, or in the direction of the fibres: they are also of different lengths and breadths, according to their use. The teeth of a saw are bent alternately to each side, that the plate may clear the wood.
46. The Ripping Saw
Is used in dividing or slitting wood in the direction of the fibres; the teeth are very large, there being eight in three inches, and the front of the teeth stand perpendicular to the line which ranges with the points: the length of the plate is about twenty eight inches.
47. The Half Ripper
Is also used in dividing wood in the direction of the fibres: the length of the plate of this is the same as the former, but there are only three teeth in the inch.
48. The Hand Saw, Pl, 13. Fig. 6.
Is both used for cutting the wood in a direction of the fibres and cross cutting: for this purpose the teeth are more reclined than the two former saws: there are fifteen teeth contained in four inches. The length of the plate is twenty six inches.
49. The Panel Saw
Is used for cutting very thin wood, either in a direction of, or transverse to the fibres. The length of the plate is the same as that of the hand saw, but there are only about six teeth in the inch. The plates of the hand saw and panel saw are thinner than the ripping saw.
50. The Tenon Saw, Pl. 13. Fig. 7.
Is generally used for cutting wood transverse to the fibres, as the shoulders of tenons. The plate of a tenon saw is from fourteen to nineteen inches in length, and the number of teeth in an inch from eight to ten. As this saw is not intended to cut through the wood its whole breadth, and as the plate would be too thin to make a straight kerf, or to keep it from buckling, there is a thick piece of iron fixed upon the other edge for this purpose, called the back.
The opening through the handle for the fingers of this and the foregoing saws is inclosed all round; and on this account is called a double handle.
51. The Sash Saw, Pl. 13. Fig. 8.
Is used by sash makers in forming the tenons of sashes: the plate is eleven inches in length. The inch contains about thirteen teeth; this saw is sometimes backed with iron, but more frequently with brass.
52. The Dove-tail Saw
Is used in dove-tailing drawers. The length of the plate is about nine inches, and the inch contains about fifteen teeth. This plate is also backed with brass. The handles of the two last saws are only single.
53. The Compass Saw, Pl. 13. Fig. 9.
Is for cutting the surfaces of wood into curved surfaces: for this purpose it is narrow, without a back, thicker on the cutting edge, as the teeth have no set. The plate is about an inch broad, next to the handle, and diminishes to about one quarter of an inch at the other extremity; here are about five teeth in the inch. The handle is single.
54. The Key-hole, or Turning Saw
Is similar to the compass saw in the plate, but the handle is long, and perforated from end to end, so that the plate may be inserted any distance within the handle. The lower part of the handle is provided with a pad, through which is inserted a screw, for the purpose of fastening the plate in the handle: this saw is used for turning out quick curves, as key-holes, and is therefore frequently culled a key-hole saw.
Peter Nicholson’s “The Mechanic’s Companion” is one of the landmark English-language books on woodworking and related building trades. First published in 1812, it’s an invaluable treatment of period techniques, with 40 detailed plates that offer an excellent look of the tools of the time, and a thorough review of the geometry you need for all types of construction.
You’ll find useful primary-source information on how to use traditional joinery tools at the bench. That’s because Nicholson – unlike other technical writers of the time – was a trained cabinetmaker, who later became an architect, prolific author and teacher. So he writes (and writes well) with the authority of experience and clarity on all things carpentry and joinery. For the other trades covered – bricklaying, masonry, slating, plastering, painting, smithing and turning – he relies on masters for solid information and relays it in easy-to-understand prose.
“Mechanic’s Companion” went through a number of printings, both in England and in the United States; this reprint is of the 1845 U.S. edition, which includes information on mid 19th-century New York City building codes (which are – to me, anyway! – fascinating). I spent a month or so in early 2018 scanning the pages of the original (at high and crisp resolution, of course) and cleaning up the foxing, as well as rebuilding many broken letters and words, pixel by pixel. My aim was to present as clean a book as possible. (I also bumped up the size by 10 percent, just to make it a little more readable.)
The 1845 edition is in back.
But after two years of fulfilling orders out of my living room and dining room – and becoming increasingly busy with freelance work for Lost Art Press and others – I decided my time and floor space could be better spent. So, Lost Art Press picked up the remainder of my print run, and will keep this important book in print (something I would not have been able to do on my own).
Like all Lost Art Press books, “Mechanic’s Companion” text is printed on acid-free paper in Smythe-sewn signatures that are reinforced with fiber tape. The interior is then wrapped in hardcover boards and cotton cloth. The book is produced entirely in the United States.
