The Other Apply it to both ends of the logs right in the middle. Draw a pencil line pitch. When the folding frames of logs obtained by the release of their last beyond the walls. Draw on a sheet of paper two of the same circle with a diameter equal to the average diameter of the logs. If your logs are processed "under the bracket ', the average diameter will be equal to the diameter of each log. The average diameter have to calculate when the logs of various thicknesses. For example, in the corner of 30 convergent beams, the sum of their sizes - 690 cm This number is (690) divide by 30 (690:30). Obtained 23 cm This will be the average diameter. Draw two lines through the center by gon (a line should be perpendicular to the other) and connect the points of their intersection with the circle. Get a square. Then divide it by two vertical opposite side into 8 pieces, the other two - in 2 parts. After this draw vertical line through the last 2 points. This line will be carried out combined with a vertical diameter at the butt-end transfer of the logs. Connect the line side, divided into 8 parts. One pattern is obtained with the parties 6 / 8 and 4 / 8, the other - from 6 / 8 and 2 / 8. Attach the plywood templates obtained. Cut them and make small cuts in places where there was a vertical line. For convenience, number the templates. Marking the cutting of logs first template attach to the end of the logs right in the middle. Try to combine cuts with drawn by the vertical diameter. Then circle the template outline. Sawing logs Once you raschertite ends, proceed to processing logs. First you need...

Steel Pipes The steel is used in most diverse objects and materials, exactly that indirectly, the steel can be found in practically all objects of nowadays. An object created with steel that is very common and is present in some places, that exactly not directly visible, they are the steel pipes. Who is deceived finds that the industrial steel pipes are used only in the industries, in the truth it are used in a infinity of things, as structures of building and houses, foundations of buildings, furniture of medium and great transport, mechanical toys and even in siderurgy. These steel pipes confer great resistance and force, supporting some types of effect and forces, guaranteeing that these forces and effect will be remained unbroken throughout the performance of several of. For this, these steel pipes are created with the steel carbon, a strengthened and resistant steel well more. Popularly, these steel pipes are also called pipes with sewing, exactly that today the visual effect that it created this name is not more visible. In the creation of the pipes, a weld process is used, old, the used weld equipment was of frequency low, what aspect of sewing in the final appearance of the steel pipe left. Today, with all the development and new techniques, the steel pipes still are manufactured with the process of weld, but in a much more high frequency, what it total removes the sewing appearance that existed old, but as the name already is in the popular taste, them still is known as steel pipes with sewing, but not more for the appearance and yes for the method of manufacture, that continues the same, even so with more advanced tools. To guarantee the security and confidence of these steel pipes, some norms had been created. They are some norms,...
