A hand-held power tool for machining a workpiece, having a drive motor, a tool holder, which can be driven by the drive motor, and which is for a working tool for machining the workpiece, and a guide element having a guide surface for guiding the hand-held power tool on the workpiece in a working direction, wherein the tool holder is mounted via a bearing arrangement such that it moves relative to the guide element and said tool holder can be driven by a servo motor arrangement, wherein the hand-held power tool can be swivelled via the bearing arrangement about at least one adjusting swivel axis passing through the guide surface at an angle, for the relative adjustment of the tool holder relative to the guide element, wherein the hand-held power tool has a control device for controlling the servo motor arrangement. The control device is configured for controlling the servo motor arrangement in such a way that the servo motor arrangement adjusts the tool holder relative to guide element, while maintaining a swivel position relative to the adjusting swivel axis with a movement direction component in parallel to the guide surface of the guide element relative to guide element.

A sawmill includes a four-stroke internal combustion engine having an output shaft for driving a sawblade. The output shaft has a longitudinal axis. The engine is mounted on the sawmill for rotation between a first operative position with the longitudinal axis of the output shaft extending at a first angle, and a second operative position with the longitudinal axis of the output shaft extending at a second angle transversely to the first angle. The engine has fuel injection to facilitate operation in the first and second operative positions and a lubrication system incorporating a wet sump. An oil pick up for the lubrication system is configured to pick up oil from the wet sump at both the first and second operative positions.

A portable machining apparatus has high operability in tilting a body with respect to a base or in machining a workpiece with the tilting body. A portable machining apparatus placeable on a long gauge placed on an upper surface of a workpiece includes a base placeable on the long gauge, a body including a blade for machining the workpiece, an angular plate fixed to the base to support the body in a tiltable manner and including a protrusion, a body support located between the body and the base and including a guide engageable with the protrusion to allow sliding of the protrusion on the guide, and a spring that urges the protrusion toward the guide.

A circular saw guide is provided having an upper frame member with a plurality of angular indicia on an edge thereof. A lower frame member is pivotable relative to said the frame member. The upper surface of the lower frame member is adapted to receive a workpiece to be cut thereon. A pivot member is provided for selectively preventing or allowing pivoting of the lower frame member relative to the upper frame member. The upper surface of the upper frame member is adapted to guide the footplate of the circular saw. By pivoting the lower frame member relative to the upper frame member, the edge of the workpiece can be aligned with a desired indicia, which is indicative of the angle that the board will be cut. A method of cutting a workpiece at a desired angle is also disclosed.

An alignment tool is disclosed for connection to a work component and for use in aligning the work component with a work piece to establish a repeatable set up for cutting or routing of the work piece, and wherein the alignment tool provides for parallel and square alignment of the work component relative to first and second edges of the work piece that are perpendicular to each other. Use of the parallel and square alignment tool aligns the work component for an operation parallel to the second edge of the work piece and the operation may be conveniently repeated on further work pieces without need to measure and mark the work pieces. Optional use of first and second parallel and square alignment tools along opposed second and third edges of a work piece that are perpendicular to a first edge provides for greater accuracy for operations having a greater length.
