ERGONOMIC HANDLE FOR A MITRE SAW

Power tool and portable support assembly

A motorized power tool and several support structures are defined. A basic embodiment includes a unibody base having base upper and base lower ends and sidewalls collectively forming an internal cavity. Atop the base upper end is disposed a table having a work support surface. A motor driven implement such as a saw blade or a sanding drum is supported so that it is adjustable and extends above the table. Wheels are disposed at the base lower end of one end of the base and an extendable handle at the other. The handle can be used to tilt the base so that all the weight is centered above the wheels and then to move the power tool. A fence is also slidably mounted on the table to adjustably position a workpiece relative to the saw blade. Support assemblies include standard-sized lumber, fitted into pockets in the base, joined pairs of legs that fold upward into the base, and an assembly having a pair of legs, between which the base can be pivoted for transport, and another pair of legs that ...

Measuring apparatus for planer

A molded limit gauge for measuring workpiece thicknesses. The limit gauge includes a body having one or more elongate ridges extending longitudinally therealong. Each ridge has a plurality of notches extending laterally through its upper portion. Each notch has a unique longitudinal dimension that is uniform. In a first preferred embodiment of the invention, the bottom surface of each notch and the land between each notch is horizontally flat. In a second preferred embodiment, each of these surfaces has a configuration of a laterally convex curve. The limit gauge body is configured such that it can be mounted atop a planing machine. So mounted, it can function as a structural top of the planing machine. Measurement of a board thickness is accomplished by attempting to slide the board through notches that appear to match its thickness. A range of board thickness is defined between the indicated sizes of two adjacent notches that respectively allow and do not allow passage of the board through ...

Ergonomic miter saw handle

An ergonomic miter saw is provided having a base and a saw arm assembly with the saw arm assembly pivotally affixed at a fixed end to the base and provided with a distal end having a handle extending outwardly therefrom. The central region of the arm assembly includes a rotary spindle supporting a cutting disk. A handle is preferably provided with an elongate grip portion sized for the user's fingers and a palm pad portion extending outwardly therefrom to underlie the heal of the user's hand to minimize bending torque on the user's wrist as the arm is lowered. Ideally, the handle is rotated in a direction opposite that the cutting disk is tilted. Preferably, the handle is adjustable oriented about the arm axis in a direction opposite that the saw blade is tiltable so that the deviation for horizontal of the handle can be minimized when the miter saw is used in a tilted cutting disk mode.

Circular saw air table

A table saw is disclosed comprising a main saw unit and an air table attachment. The air table is mounted adjacent a main support surface of the main saw unit, and includes a body portion and a generally planar table top. The body portion has a plurality of subsections formed therein. The table top is substantially coplanar with the main support surface, and is attached to the body portion to cover the subsections so that a plurality of holes through the table top communicate between the subsections and the exterior. A shop vacuum produces either a partial vacuum or a stream of pressurized air, and a manifold attached to the body portion selectively communicates the vacuum or stream of air to one or more of the subsections to respectively produce either a suction force or a supporting air cushion over a variable portion of the table top. Preferably, the air table is movable along the front and rear guide rails in a direction transverse to the direction of rotation of the saw blade. The air table can also be moved from one side of the rotatable blade to the other side to accommodate the workpiece.
