A wheeled saw support apparatus for creating horizontal cuts in drywall and other vertical surfaces includes a base platform and a plurality of wheels is coupled to a base bottom side. A pair of side supports is coupled to a base top side adjacent a base front side. The pair of side supports comprises a left side support and a right side support coupled adjacent a base left side and a base right side, respectively. A pair of crossbars is coupled to the pair of side supports with each crossbar extending between a support inner side of each side support. A plurality of mounting clamps is coupled to the pair of crossbars. The plurality of mounting clamps secures a circular saw to the pair of crossbars.

A system for cutting narrow workpieces having a track that extends a width between a cutting edge and a non-cutting edge. One or more measuring bodies are connected to a slot adjacent the non-cutting edge that include a measuring bar that extends forward from the front side of the measuring body and under the track as well as extends rearward from the rear side of the measuring body. The measuring bar slides within the measuring body to accommodate the desired workpiece thickness. The measuring bar includes measuring indicia and a measuring member that facilitates measurement of workpiece thickness. Measuring body includes a locking member that locks the measuring bar at a desired thickness. Measuring member may be adjusted to calibrate the measuring member to the track and saw using a locking member. Measuring body also includes a support leg and associated locking mechanism that levels the measuring body.

A portable cross cut system is presented that includes a main body having a reference edge configured to be aligned against an edge of a workpiece and an engagement member configured to be laid on top of the workpiece. A first guide edge extends along an outward edge of the main body and the engagement member and is configured to guide an edge of a baseplate of a cutting tool during a cutting operation. The main body includes a blade offset member having an arm that moves between an extended position and a retracted position. When the arm is extended the outward end of the arm indicates the position of a cut line so that the user can easily align the position of the portable cross cut system to easily and accurately make cuts in a workpiece.

Plunge saws with cut indicators and methods of operating plunge saws are disclosed herein. The plunge saws include a motor and an arbor, which is configured to operatively attach a circular saw blade to the plunge saw and to receive a torque from the motor. The plunge saws also include a base plate and a base plate pivot. The plunge saws further include a plunge mechanism, which is configured to be selectively actuated, by a user of the plunge saw and during operative use of the plunge saw to cut a workpiece, to transition the plunge saw from a retracted orientation to a plunged orientation and to plunge the circular saw blade into the workpiece. The plunge saws also include a cut indicator, which is configured to project a light line onto the workpiece to visually indicate, on the workpiece, a location of an edge of the circular saw blade.

An attachment structure for attaching an auxiliary fitting such as a parallel ruler to a portable machining apparatus allows simpler assembly and maintenance. A portable machining apparatus includes a base having a lower surface to be in contact with a workpiece, a machining body supported on an upper surface of the base, and a mount that receives an auxiliary fitting removably attachable to the base. The mount includes an internal threaded fastener detachably supported on the base, an external threaded fastener screwed with the internal threaded fastener to be tightened with the internal threaded fastener to press the auxiliary fitting onto the base, and a locking section that locks the external threaded fastener with respect to the internal threaded fastener.
