Device (100) for sawing logs to a predetermined length, comprising a rotatably mounted saw drum (110) which is non-rotatably connected to a driven rotating shaft (105), wherein the saw drum (110) has a plurality of feed slots (120) for feeding logs to be sawn, wherein the saw drum (110) together with each of the feed slots (120) is divided into two parts and an upper part of a feed slot (120) is arranged in an upper saw drum part (111) and a lower part of a corresponding feed slot (120) is arranged in a lower saw drum part (112) and the saw blade (131) of a circular saw (130) partially engages in a gap between the upper saw drum part (111) and a corresponding lower saw drum part (112), wherein by rotation of the saw drum (110) each feed slot (120) is brought into the effective area of ​​the saw blade (131) of the circular saw (130) is reached, characterized by that the rotating shaft (105) is arranged at an angle of 30° to 60° to the horizontal, and the upper saw drum part (111) has a lower stop (107) on its lower side, which is supported against an upper stop on the upper side of the lower saw drum part (112) forming the gap, wherein the upper saw drum part (111) is mounted so as to be displaceable upwards along the rotating shaft (105) against the force of gravity and the displacement of the upper saw drum part (111) is limited by an upper stop (106) of the rotating shaft (105), and the lower saw drum part (112) is mounted so as not to be displaceable along the rotating shaft (105), wherein, in the event of a larger saw chip falling in and becoming trapped between the upper saw drum part (111) and the saw blade (131) of the circular saw (130), the action of the saw chip causes a lower limiting edge of the upper saw drum part (111) to be moved upwards along the rotating shaft (105) against the force of gravity, thereby increasing the gap between the saw blade (131) of the circular saw (130) and the lower limiting edge of the upper saw drum part (111) and automatically freeing the saw chip from its jammed position.

A reciprocating power tool may include a driving system including a motor and a transmission received in a housing to drive a reciprocating mechanism. A selection mechanism may provide for selection of an operation mode of the reciprocating tool, including a linear mode of operation and at least one orbital mode of operation. Motion of a reciprocating shaft of the reciprocating mechanism may be guided by a guide bracket that is fixed in the housing and an orbit bushing that is movably coupled in the housing. In the linear mode of operation of the tool, the bushing is in a first position relative to the guide bracket. In an orbital mode of operation of the tool, the bushing is moved to a second position relative to the guide bracket.

A wood processing system, components thereof, and associated methods. Elongate wood members are cut from a piece of wood such as a log. The elongate wood members may be cut in a plurality of adjacent rows. The elongate wood members in a row may each have a generally triangular cross-sectional shape. The generally triangular cross-sectional shape of the elongate wood members of a row may alternate in orientation along the row.
