Collapsible and transportable systems for supporting miter saw assemblies. In one illustrative embodiment, a table assembly has two opposite main nodes at either end that support an upper bench top therebetween. Two legs extend from each main node to support the table. Two parallel support members extends through the main nodes underneath the bench top. A saw support table may be removably securable to the parallel support members extending out past the bench and allows a miter saw secured thereto to be adjusted such that the miter saw cutting table is co-planar with the bench top. A sliding locking member may be attached to the bench top to define a fixed distance for the length of material being cut. A second saw support table may be disposed on folding adjustable legs attached to the legs extending from a main node to support a table saw coplanar with the bench top.

A miter saw includes a base assembly configured to at least partially support a workpiece on the miter saw. The miter saw also includes a turntable pivotably coupled to the base assembly about a vertical miter axis in a first rotational direction and a second rotational direction opposite the first rotational direction. The turntable is also configured to at least partially support the workpiece on the miter saw. The miter saw also includes a constraining device coupled between the base assembly and the turntable. The constraining device is configured to inhibit movement of the turntable relative to the base assembly in a direction different than the first and second rotational directions.

A miter saw has a base having a detent notch, a table rotatably connectable to the base, a pivoting assembly connected to the table, and a saw assembly supported by the pivoting assembly. The saw assembly has a blade movable downwardly for a cutting operation. A locking mechanism is disposed on the table. The locking mechanism is movable between an unlocked position and a locked position for selectively unlocking and locking the table for rotational movement relative to the base about the miter axis. The locking mechanism has a lock lever rotatably connected to the table. The lock lever has a handle for moving locking mechanism between the locked and unlocked positions. The saw also has a miter detent assembly for selectively engaging and disengaging the detent notch.

The present invention relates generally to the field of table saws. More specifically, the present invention relates to a table saw attachable storage device primarily comprised of a body further comprised of an interior cavity that can receive and store a table saw fence. In differing embodiments, the body may magnetically attach to a table saw cutting surface in a variety of locations or attach via at least one fastener and a mounting bracket. The body may further be comprised of a pencil retaining compartment further comprised of a pencil sharpener. In addition, the device may be comprised of at least one end cap to prevent sawdust from entering into the body when not in use.

An improved cutting device with an integrated and interruptible auxiliary power supply. In a preferred embodiment, the improved cutting device is a miter saw having a trigger mechanism for controlling a cutting implement, and at least one 120V or 240V auxiliary power outlet. Electrical power is only provided to the cutting implement and the auxiliary power outlet when the triggering or a similar mechanism is activated, and the release of the triggering mechanism by the user automatically shuts off electrical power to both the cutting implement and the at least one auxiliary power outlet. The auxiliary power outlet is useful for powering any number of different accessories including, without limitation, a light, vacuum source, etc., and is repositionable.
