The pit saw leaves marks on wood that look like this ///////////.The pit saw is a two-man powered saw used in America before 1680 to cut logs into boards.During the Industrial Revolution, the method of making nails, screws, hinges, latches, and of milling lumber changed often. The style of nails changed a dozen times, the hinge changed four times, the screw changed three times, and so did latches and pulls.The methods of working wood also changed during this time.The puritan New England cabinetmakers built simple unadorned cupboards painted in drab colors.The Shakers are well known for their simple but elegant furniture.The circular saw was limited to cutting thin pieces of wood such as shingles, clapboards, and laths until the early 1900s.Cupboards and other furniture in which the large size boards used in their construction are circular saw cut can date to 1880, but usually date after 1900.
For the first ten years of production, machine made screws were made with no slot in their head.
Therefore, most boards used in the construction of early cupboards show signs of being cut with an up-and-down saw.
The circular saw although introduced in the mid 1850s could not be made big enough and powerful enough to cut lumber of the size used in furniture construction until 1880.
After 1700, its major use was as a large jigsaw to shape knees, ribbing, and planking for ships.
The up-and-down saw, was used in this country from the 1680s until early in the 1900s.
Country furniture does have its styles based predominately on religion and region.
