A circular method of sawing raw materials can be used to separate lumber from the center of low-quality zones of thick logs affected by false cores or sound rot in the woodworking industry. Each board is sawed from the side of the log, and the log is rotated 90 ° three times while a certain number of boards are sawed. A log can be split into lumber by cutting thin boards from the side to get a single-edged beam. Rotating a single-edged beam 90° and cutting thin boards from its lateral part makes a two-edged beam with two adjacent sawn sides, then it turns 90° and gets a bunch of boards.
The log splitter for sale reduces wood waste in laths and sawdust. This problem can be solved by the fact that when you cut logs into lumber, you saw thin boards from the side of the log to make a single-edged beam, turned the beam 90 o, and cut thin lumber from its lateral part to make a two-edged beam with two sawn sides that are next to each other. Following that, it's turned 90 degrees, then sawn into thin and thick lumber with one trimmed edge, and the thickness of thick lumber is set from the width of thin lumber.
Using one trimmed edge, the drawing shows how logs are cut into lumber. The inventive way to cut logs into lumber is to cut thin unedged lumber (boards) from the side surface of the log, then rotate it 90° to saw off the following thin lumber (boards), so you get a beam with two adjacent sawn sides. Next, it's rotated 90 degrees and sawn into thin boards without edges and thick lumber with one trimmed edge. After cutting logs, lumber on thin boards is made up to 0.707 vertex radius from the center of the end face of the log. From the condition of equal or multiplicity of its thin lumber width, thick boards are set thick.
The invention makes thick boards with a single edge, so there's less wood waste in inspection rails and you don't have to remove saws when cutting narrow edged lumber or workpieces longitudinally. Having thick boards the same thickness as thin lumber allows you to reduce waste in sawdust and/or runner rails.
