Exemplary embodiments of a “Smart Cut” system and method for efficiently and accurately converting material length using a powered saw, such as a miter saw, are disclosed. Certain embodiments are configured such that a user of a miter saw may position a board or other material beneath the miter saw blade, and cut the material to a desired length, without any need to mark a measurement on the material prior to cutting it. It is an advantage of certain embodiments that a typical retractable tape measurement device, a portable tool that is ubiquitous in the construction industry, may be leveraged to indicate proper positioning of the material prior to cutting.

A two-part pivotable block component for mounting interposed a piece of industrial equipment and its mounting base. The two-part pivotable block component comprises an upper first part that is engageable with the base of the industrial equipment, and a lower second part that is engageable with a mount for the industrial equipment. The first part of the pivotable block component has an inclined surface in a first plane for pivotably engaging an inclined surface provided therefore on the second part of the pivotable block component. The inclined surface of the second part of the pivotable block component is in a second plane. The two-part pivotable block component is suitable for use with industrial equipment exemplified by electrical motors, hydraulic-driven motors, pressure-driven motors, and pumps. The two-part pivotable block component is also suitable for aligning arbors cooperating with industrial equipment.

Simulated bog-down system and method for power tools. One power tool according to an example embodiment includes a power source and a motor selectively coupled to the power source. The motor includes a rotor and stator windings. The power tool includes an actuator configured to generate a drive request signal and a power switching network configured to selectively couple the power source to the stator windings of the motor. The power tool includes an electronic processor coupled to the power source, the actuator, and the power switching network. The electronic processor is configured to detect a load on the power tool and compare the load to a threshold. The electronic processor is configured to determine that the load is greater than the threshold, and to control the power switching network to simulate bog-down in response to determining that the load is greater than the threshold.

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.
