We include research citations assisting in understanding the history and development of the mechanically-operated reciprocating saw or a mechanical and often portable replacement for the hand-operated "pit saw".

Generations of types of adzes, axes, broadaxes and saws used in cutting beams, and similar details are readily available on many buildings. The marks left by these tools offer both clues to building age and wonderful aesthetic detail.

Below, in rough chronological order, we illustrate different types of saw and tool cut marks in wood: adze cuts, hand sawn pit saw marks, mechanically-operated pit saw marks, circular saw marks, and unmarked, planed modern dimensional lumber.

We discuss the visual comparison of adze marks, axe marks, hand sawn lumber, mechanical pit sawn lumber, and circular saw mill cut lumber and boards. Timber frame construction initially used hand hewn beams, cut roughly rectangular by an adze and axe. Later timber frame construction used sawn beams and still later wood frame construction used sawn sills, studs, joists and rafters.

Photo at page top: pit saw kerf marks on a sawn beam in a home in Cold Spring New York. Hand hewn beams, chopped and then sized with an adze and axe were used in North America from the 's into the late 's. Our photograph above shows the scoring axe cuts and hewing adze cuts that are normally visible in the rough surface of hand hewn wood structural beams. The tool marks on the antique beam shown here were most liekly made using an adze or a combination of a broad-axe and adze.

The flattening was not done with an axe alone, as we can see the smooth surface dating wood by saw marks by the adze on some of the beam's surfaces. An understanding of how hand-hewn beams were cut, for example, can permit the careful observer to not only recognize the type and age of building framing, but even to understand just where the worker was standing when a blow from a tool was delivered to a building framing member.

Using an axe, broad-axe, or broad-hatchet, or possibly only an adze, a hoe-like cutting tool with wooden offset handle, the worker would make make a series of cuts along the round up-facing surface of a log. For those who had one, a chalk line was used to mark a straight line along one or two sides of the log to guide the cutting, and the scoring cuts would be made to about the depth of the line.

With a chalk line or more likey working just by eye, the worker most often used a broad-axe or a broad hatchet to make the cuts into dating wood by saw marks log surface. Rough scoring cuts may have been as far as two feet apart along the log surface, and were not made to the full depth of the string line or sight line that represented the desired flat surface of the finished beam.

Between these scoring cuts the wood would be chipped out by prying with the edge of the scoring axe or hatchet. Additional scoring cuts closer to the final cut-line might be made using the broadaxe or broad hatchet or possibly the adze itself, followed by additional chipping. In adult women final series of cuts, the sharp adze or more often an axe, broad aze or broad hatchet was used to cut away the curled "chip" of rounded log surface cut and then the surface was "planed" by the adze.

The axe cut was made at the base of the chip of wood cut and lifted by the adze.


In our photo of a hewn beam bove, the vertical cuts across the height of the log face red arrow are the cuts that were made to remove the chip, while the scalloped green arrow or split orange arrow rectangular face cuts are the marks left either by the adze blade or by the splits in the wood surface when the adze-cut chip was removed. You can see by the fact that some of the cut surfaces are smooth that the hewing cuts were made by an adze.

A skilled worker might use a sharp broadaxe to cut on-the-flat along the log surface to flatten it to its final face when no adze were at hand; in that case we might see smooth but more rounded-scalloped cuts, or cuts that were angled into the wood and thus less-flat along the beam surface as the axe blade could not be swung absolutely parallel to the beam face where the blade of the axe or hatchet flattened the beam surface to the final cut-line.

More often in Colonial America the final beam facing was peformed using an dating wood by saw marks to dating wood by saw marks the surface. Had the chips just been split out of the you'd not see such flat, smooth cuts parallel to the beam face on the log face as are left by the adze. This detail offers a very personal connection to the age of a building and to its past construction.


You can actually place yourself where the worker stood to swing the tool. When pairs of individual timers are joined to one another with custom-fitting cuts to match their individual irregularities, most likely the European scribe rule procedure was being followed. Finding your true love of the timbers were pre-assembled on the ground, scribed using a metal awl to make cut marks so that the joint would fit tightly, a hand auger bored holes for the treenail or wooden peg, and reference marks were made on each beam or post end to show the proper connection points dating wood by saw marks assembly.

You can see some of these marriage marks on the sawn beams in my photo below. Typically the marriage marks or numnbers were cut as combinations of straight lines to form roman numerals. The marriage marks in the photo were on rafters in a Poughkeepsie home built in about and repaired in the 's by the dating wood by saw marks [DF].

Square-rule construction ended the practice of custom-joining each pair of beam or post ends by cutting and joining timbers or other wood members using a uniform or standard joint shape and dimension. As with later mass-production this allowed any two ends of beams or posts to be joined together, making the numbering of mating post or beam ends using marriage marks unnecessasry. While I've read that Square-rule construction became domninant in North Ameria byI'm doubtful about how widespread it was at that time, given the many barns or other structures we date to later than that era that still used marriage marks on their posts and beams.
