Remember that people have recycled building materials for thousands of years; the beams in the barn may be much older–or much younger–than the rest of the barn. Never depend on a single determinant; documentary resources may provide as much–or more–information about the structure as a single piece of wood which may or may not have been original to the building. If you’re planning to demolish an old barn, possibly because it has become unstable and unsafe or possibly because you need the acreage for another purpose, you might be faced with a requirement to document the barn, its materials and its age to satisfy a local preservation ordinance.
Even if you are not planning to demolish the barn and are simply doing research into local history or seeking more information on your own property, determining the age of the wooden beams will tell you much about the structure’s history. Look at the overall construction of the barn and determine whether it was post-and-beam or post-tension construction, or some combination of those–or other–methods. Two key things to remember are that construction methods overlapped and may represent a regional influence or the builder’s preferences: not all residences in the High Italianate style are of the later-middle period of the Victorian Era, nor are all residences from the later-middle period of the Victorian Era of the High Italianate style.
Examine any saw and kerf marks visible on the beams; a magnifying glass may be helpful in this endeavor. As any blade cuts through wood, it leaves marks; a pit saw, gash saw and circular saw each leave a very different type of mark. The pit saw left uneven and irregular kerf marks, and was in use from the earliest days of American settlement; the gash saw left large, regular “up and down” kerf marks–it was powered by a water wheel–lumber with this kind of kerf marking is most often found on the East Coast and may date date from as early as the s to as late as the middle s–and the circular saw left an odd circular kerf mark appearing on wood sawn after The type and character of these marks often indicate what type of blade was used and perhaps even information about the sawyer and his equipment.
