How to Find Out the Age of a Dining Table
When you want to refinish old wooden furniture, the best place to look is the family storeroom: Check the attic, basement, garage, or wherever unwanted furniture has collected. You may also discover a real antique or two — pieces handed down through the family for generations. Other good sources are secondhand stores, household auctions, and garage sales. With furniture, as with anything else, one person’s junk is another another’s treasure. Antique stores are a good place to find furniture to refinish, but expect to pay for these pieces. If you’re interested in antiques, recent or old, research before you buy anything.
What are Kerf Marks?
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.
Pit sawn surface: the finish is characterised by saw-marks at about 75 to 85° to the With imported softwoods, which mainly date from the 17th century onwards,.
The saw marks on an old piece of lumber can give information about the type of mill that was used, but using the marks for dating the board needs to be done with great caution since periods in which different types of sawmills were used overlap by many decades in New England and elsewhere. The marks on the right hand end of this board are the “stub shot” which show that the board was not sawn through the end of the log, but rather the last few inches were split off. Why not saw through the end of the log?

The Medallions and Timeline of Saw Manufacture
If only historic timbers could talk — what questions you could ask, what stories they could tell. This is done by examining the surfaces of the timbers, often with a low angled light, for signs of both the method and the type of conversion. The information gained from these primary sources is invaluable for interpretation reports or conservation plans, helping to build up a picture of the chronology and development of the structure in question. Documentary evidence and scientific analysis can also be used but the initial appraisal is often based on a stylistic judgment which relies on understanding what you are looking at and putting it into context.
It is worth remembering that nearly always the part of the tree the log that we are interested in derives from the main trunk or bole, not the branches or roots, although sometimes portions of branch or root stock are left attached to the main trunk for specific purposes, such as jowl posts. In the case of homegrown hardwoods — typically oak and elm from managed woodland, parks or hedgerows — the timber trees are often oval in section and crooked as well as tapering along their length.
The most important saw I have is the one I need to do the task in front of me at that moment. Author: Mark Clement; Publish date: Apr 19, are configured for cutting the hodgepodge of nail-embedded wood, plaster, drywall, Always look for saw marks on an appearance-face cut and sand them out.
The chipped flint knife , with its irregular edge, was not a saw in the proper sense, for though it could sever wood fibres and gash bone or horn, it could not remove small pieces of material in the manner of a saw. Furthermore, the necessarily broad V-shaped profile of the flint saw severely limited its penetration into the workpiece; the nature of its cut was limited to making an encircling groove on a branch or a notch on something flat. The true saw, a blade with teeth, one of the first great innovations of the Metal Age, was a completely new tool , able to cut through wood instead of merely gashing the surface.
It developed with smelted copper , from which a blade could be cast. Many of the early copper saws have the general appearance of large meat -carving knives, with bone or wooden handles riveted to a tang at one end. Egyptian illustrations from about bce onward show the saw being used to rip boards, the timber being lashed to a vertical post set into the ground. The use of relatively narrow, thin, and not quite flat blades made of a metal having a tendency to buckle, coupled with poorly shaped teeth that created high friction , required that the cutting take place on the pull stroke.
Dating Wood By Saw Marks
Antique Furniture is one of the most fascinating sections of antique collecting. We buy what we like. Most antique furniture tends to be purchased by ordinary everyday people, rather than dedicated antique furniture collectors. In other words, more vintage furniture is acquired for its beauty and function rather than the profit potential of a piece.
If the wood shows circular or arc-shaped marks, it was cut by a circular saw, not in use until about The finish on the wood can also date the piece.
A sawmill or lumber mill is a facility where logs are cut into lumber. Modern sawmills use a motorized saw to cut logs lengthwise to make long pieces, and crosswise to length depending on standard or custom sizes dimensional lumber. The “portable” sawmill is of simple operation. The log lies flat on a steel bed, and the motorized saw cuts the log horizontally along the length of the bed, by the operator manually pushing the saw. The most basic kind of sawmill consists of a chainsaw and a customized jig “Alaskan sawmill” , with similar horizontal operation.
Before the invention of the sawmill, boards were made in various manual ways, either rived split and planed , hewn , or more often hand sawn by two men with a whipsaw , one above and another in a saw pit below. The earliest known mechanical mill is the Hierapolis sawmill , a Roman water-powered stone mill at Hierapolis , Asia Minor dating back to the 3rd century AD. Other water-powered mills followed and by the 11th century they were widespread in Spain and North Africa, the Middle East and Central Asia, and in the next few centuries, spread across Europe.
The circular motion of the wheel was converted to a reciprocating motion at the saw blade. Generally, only the saw was powered, and the logs had to be loaded and moved by hand. An early improvement was the development of a movable carriage, also water powered, to move the log steadily through the saw blade. By the time of the Industrial Revolution in the 18th century, the circular saw blade had been invented, and with the development of steam power in the 19th century, a much greater degree of mechanisation was possible.

Since we expect them to be identical they appear to be until inspected and measured. He and his journeymen and apprentices accomplished these tasks with an amazingly small array of hand tools, some of which would be familiar to us today and some that many of us would have no idea how to employ. Some of these tools, and the techniques used in conjunction with them, left marks in the wood that allow us to catch a glimpse of the action, frozen in time for our inspection.
SAWS — Virtually all cutting of lumber was done with a handsaw, introduced in the Bronze Age, used by the Romans who recognized the benefit of offsetting the teeth and perfected in the 18th century. The saw utilized in the initial shaping and cutting of rough lumber was the panel saw, developed by the Dutch in the 17th century. This saw is what we think of today when we think of a handsaw.
It has a long tapered, stout but flexible blade and a pistol grip handle. It was used to rip and crosscut larger pieces. These saws had a brass or steel spline on the top of the thin blade to stiffen it and allow precision cutting such as was required for dovetails. Handsaw marks are relatively rare since sawn surfaces are usually either further dressed or concealed within a joint.
The best place to look for them is on the bottom of chair legs, which are carved rather than turned and on the inward facing surfaces of carved legs. The most common saw mark is the thin overcut left on a dovetail joint.
