Tree-Ring Dating (Dendrochronology)
The invention relates to an assembly comprising two jigs which can be used to produce a dovetail mortise and tenon in order to assemble members of a frame. This present invention concerns a device or arrangement, an assembly or a kit, that includes jigs employed for the execution of dovetail mortise and tenon joints, intended for assembling the parts of timber beams. In the area of roof timbers, the assemblies usually employed consist of straight mortise and tenon joints.

Notably, after a massive earthquake caused major structural damage to the mosque in , a lot of work was done to strengthen the building, and a number of wooden beams were removed, many of which are now in the Rockefeller Museum in East Jerusalem.
In the s, more wooden beams were removed from the Temple Mount and some were sold to a merchant in Ramallah. Some Israelis actually purchased these beams and sent them for Carbon 14 and dendrochronological tree ring dating at the Weizmann Institute. Most of the beams were found to be from cyprus trees or cedar trees from Lebanon and some were oak from Turkey. While the vast majority of tested beams dated to the Byzantine period 6th century CE , some of the beams date much earlier.
Dendrochronology in Dating Timber Framed Buildings and Structures
This chronometric technique is the most precise dating tool available to archaeologists who work in areas where trees are particularly responsive to annual variations in precipitation, such as the American Southwest. Developed by astronomer A. Douglass in the s, dendrochronology—or tree-ring dating—involves matching the pattern of tree rings in archaeological wood samples to the pattern of tree rings in a sequence of overlapping samples extending back thousands of years.
These cross-dated sequences, called chronologies, vary from one part of the world to the next. In the American Southwest, the unbroken sequence extends back to B.
We are updating a Florida ranch style house to sell. The family room is open to the kitchen to make a combined area of square feet. The combined window area is a mere 50 square feet, one window beneath a broad overhang and the other two facing trees close to the house. As you may imagine, the two rooms are not light and bright! To lighten them we are installing a light colored floor, refacing the floor to ceiling family room fireplace with light colored stone and of course we will be using light colored paint everywhere.
My question relates to the ceiling beams in the family room. The beams are rough sawn cedar and darkened with age. They darken and lower the ceiling considerably. A remodeler friend says we should remove them completely to make the room look as large and bright as possible and because he says beams like these are dated. I am not so sure. The location of the house is lovely. It is surrounded by mature trees and has limited views of a large lake.
It has a rural feel that I think is echoed by the rustic beams and stone fireplace. The pitched ceiling and beams are the only architectural features the house has.
A very large selection of beams to choose from is in stock. We highly recommend visiting our shop to view your options in person. Dating back to the s or earlier, reclaimed hand-hewn barn beams are typically cut and shaped with hard blows by an ax or chisel. The result is a rough, rustic look. Hand—hewn beams will normally have mortise pockets in them, as they were most often part of the upper framing of a mortise and tenon structure.
In addition to the size, what makes them very desirable is that they have very few, if any, mortise pockets.
Carved wooden panels and beams from the Al-Aqsa Mosque, built in Jerusalem in the 8th century, were identified botanically and dated by 14C AMS.
Upon encountering a new site, the archaeologist immediately requires information about its age in order to set it in context with other sites. In research into our heritage the conservationist or architect may be able to date the general period of a building he is working with from either the situation, materials of construction, type of timber joints or other stylistic features. Almost certainly the century or portion of a century when it was built may be assigned with some certainty.
However, as more and more work is done and increasing numbers of structures with complex constructional phases are encountered, the general features may not be sufficient to give the accuracy in dating that is currently required. If research into other sources of information also fails to throw light on the building’s history, resort may be made to the various scientific methods of dating.
This article outlines three of the most important methods currently used for dating buildings or, in a complex situation, the order of construction within the building. These are: dendrochronology or ‘tree-ring’ dating , radiocarbon dating and thermoluminescence dating. Each method has a distinct role in the investigation of historic buildings.
Oh no, there’s been an error
How old is my barn? Good question! Probably the most common question asked about barns, and yet one of the hardest ones to answer. Because barns are too much like fences. We build them, or at least we used to, because they serve a purpose. Occasionally you will find a date chiseled in a foundation stone, or carved into a timber, and more commonly you will find a date in the slates on the roof.

InspectAPedia tolerates no conflicts of interest. We have no relationship with advertisers, products, or services discussed at this website. We include a table of modern dimensional lumber nominal and actual sizes for kiln dried and treated wood. 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.
