An angle guide assembly for being coupled to a table body that slides along a longitudinal axis relative to a base of a saw. The angle guide assembly includes an attachment member configured to attach the angle guide assembly to the table body; a guide body and an angled fence pivotally coupled to the guide body between a first orientation in which a workpiece can be placed at an angle to the longitudinal axis along a first guide surface of the guide body by placing the workpiece against the fence surface, and a second orientation in which a workpiece can be placed at an angle to the longitudinal axis along a second guide surface of the guide body by placing the workpiece against the fence surface.

A fence and stop assembly system and method of use thereof are disclosed. The fence and stop assembly system may include a fence configured to guide and/or secure a workpiece, and a track defined in the fence extending along a length thereof. The stop assembly may be operably engaged with the track. The stop assembly may include a stop portion configured to engage the workpiece such that at least a part of the stop portion is positioned within the track. The method may include operably engaging a stop assembly with a track defined in a fence such that at least a part of a stop portion of the stop assembly is positioned within the track.

A stop assembly may include a first portion configured to selectively operably engage a track of a tool and a stop portion operably engaged with the first portion configured to releasably engage a workpiece. The stop portion may be pivotable between a disengaged position and an engaged position relative to the first portion. The stop portion may move in a rotational direction toward the first portion when moving from the disengaged position to the engaged position. A method of use may include pivoting a stop portion of a stop assembly, about a pivot axis defined by a pivot shaft of the stop assembly, to an engaged position such that the stop portion moves in a rotational direction toward a first portion of the stop assembly.

An apparatus for performing repeatable, accurate compound miter cuts takes the form of a gauge and associated plate that are attached to a conventional miter saw. The gauge includes a pair of hinged flaps that are adjustable so that the user can move the two flaps to correspond to the measured lean angle and the measured miter angle, creating the proper three-dimensional orientation for the compound miter cut. A separate plate member is attached to the saw itself (in a plane parallel to the saw blade), and is used as a guide to align the blade to the gauge. An associated set of pivot stops (for both the arm and the table) are used in conjunction with the gauge and the plate to form all possible combinations of inside and outside angles in a repeatable manner without needing to perform any calculations of the angles.

A miter saw includes a base assembly and a saw unit pivotably coupled to the base assembly. The saw unit includes a saw blade and a lower blade guard covering a lower portion of the saw blade. The miter saw also includes a linkage for raising the lower blade guard to expose the lower portion of the saw blade as the saw unit is lowered toward the base assembly. The linkage is operable to apply a force to the lower blade guard for holding the lower blade guard in a raised position, without any input from the operator of the miter saw and without changing the length of the linkage, to facilitate changing the saw blade.

Various safety systems for power tools, and in particular table saws include detection systems for detecting a dangerous condition relative to a blade of the power tool, reaction systems for taking mitigation action in response to detection of a dangerous condition. The safety system may detect, prevent, and/or mitigate a dangerous condition associated with the power tool.

Techniques utilize a fence assembly which includes a fence member constructed and arranged to (i) install on a saw base and (ii) provide a first surface that restricts movement of an object in a first direction when the fence member is installed on the saw base. The fence assembly further includes a stop member constructed and arranged to provide a second surface that restricts movement of the object in a second direction that is different from the first direction when the stop member is in a fixed position relative to the fence member. The fence member further includes positioning hardware constructed and arranged to position the stop member in the fixed position relative to the fence member. Actuation of the positioning hardware enables the stop member to be adjusted to accommodate different object for cutting.

A bevel angle lock and detent system for a miter saw includes a first locking unit fixed relative to the turntable and a second locking unit coupled to a bevel arm of the miter saw. An actuator is moveable between a first position and a second position to move the second locking unit relative to the first locking unit. In the first position, a brake member of the second locking unit is engaged with an arcuate surface of the first locking unit to lock a saw unit relative to a turntable. In the second position, the brake member is disengaged from the arcuate surface, thereby permitting pivoting movement of the saw unit, and a detent member of the second locking unit is engageable a detent aperture of the first locking unit to locate the saw unit relative to the turntable at one predetermined bevel angle.
