What is a drink?

The saw is an aluminous excavation that can be used to cut the logs into plates. In order to control the saw, one man stands under the logo and the other over him to work on two persons. Some saws were dug off the ground from zero, while others took over a natural feature such as a moat or waterfront. No matter how the pit was made, it would often be covered to prevent water from filling. The saws were common before the invention and since then they have fallen into abuse.

Before the invention and widespread use, the saws were used to create hand -stupid boards. These pits were often dug off the ground, although in other cases natural depression in the ground was created and used. At a time when they were widely used, many cities and other places saw for the creation of boards and boards for the local building. It was also common for the saw to dig up the logging operation to reduce the distancestromes to be carried.

Each saw was usually operated by at least two workers known as Sawyers. One man would work on a saw from the bottom of the pit while the other would pull above the log. Each worker would usually use different wedges to keep the cut open and oils to reduce friction if it starts to close. The man above was usually responsible for the integrity of each cut, because the boards and boards created in this way were usually made of hand.

Because the saws are dug off the ground, they tend to fill with rainwater and drain quite easily. Many of these structures were built in areas that had natural coverage from the surrounding trees and hard -wrapped soil that could prevent outflow, because the flooded saw could not usually be used. In other cases, these problems were prevented from covering the saw with some roof. The roofs also provided employees' level of protection from elements.

After the introduction of the cutting mills, the practice of cutting plates and boards in the saws fell out.Early saws that used saws driven by water wheels could often create up to 200 boards per day. A well -trained couple Sawyers was usually limited to about a dozen boards a day, so the lumber process was much more efficient and less demanding.
