A saw blade guiding device for a saw, in particular a jig saw, includes at least one guide unit for guiding a saw blade of the saw in a sawing operation. The guide unit has two guide elements, which are provided to together form a guide holder for the saw blade, wherein a width of the guide holder is adjustable by the two guide elements. At least one guide element of the two guide elements has, on a side facing the other guide element, at least two guide faces, each of which is provided to form a side face of the guide holder. The at least two guide faces are offset with respect to one another at least substantially parallel to an extent of the width the guide holder.

A guide dresser for cutting or machining a saw guide includes a carriage assembly on which the saw guide is mounted. The carriage assembly includes a faceplate and a retaining plate for engaging opposed surfaces of the saw guide. A rod extends from the faceplate through the saw guide and the retaining plate, with at least a portion of the rod being threaded. A load cell is placed against the retaining plate and a nut is threaded along the rod until the saw guide is clamped against the faceplate. The load cell is able to convert the force exerted by the nut against the load cell into an electrical signal. The electrical signal is transmitted to a computer, which is able to determine a measurement of the torque exerted by the nut.

Machining guides and methods relating thereto are described. One example of the machining guide, according to the present arrangement, includes: (i) two or more frames, each of which includes(a) a first guide member including first multiple plates; (b) a second guide member including second multiple plates; and (c) a pivoting connection pivotably connecting the first guide member and the second guide member, and wherein, during an operative state of the machining guide, one or both of the first and the second guide members of two or more of the frames pivot about the pivoting connection to allow two or more of the frames to be disposed around the workpiece; and (ii) one or more spacer plates being disposed between each of the frames and define a kerf between each of the frames such that, during the operative state of the machining guide, a tool through the kerf is capable of machining the workpiece.

A jigsaw that uses a cutting blade generally includes a housing containing a motor activated by a trigger assembly. A blade storage compartment is recessed in the housing. A platform is provided in the blade storage compartment having a first edge that at least partially defines a first recess that extends further into the housing beyond the platform. A member is connected to the platform that produces a magnetic field that releasably secures the cutting blade to the platform. The magnetic field is configured to permit a user to tilt the cutting blade about the first edge of the platform into the first recess to overcome the magnetic field and remove the cutting blade from the storage compartment.

The problem of penetrating through nets and other objects is solved by cutting the object using various cutter systems, which include, for example a track and a moving carriage containing a cutter, a stationary carriage with a fixed or rotating arm, and/or abrasive cutters. The object is cut by a severing, slicing, or wearing action caused by a moveable blade or abrasive surface. An underwater vehicle incorporating an embodiment of the cutter system can cut a sufficiently large opening in the object to allow the vehicle to pass through.

A tool for removing a bushing from a workpiece includes a tool body, a first reference, and a second reference for positioning the tool body on a workpiece. A saw slot is defined through the tool body to provide access to the workpiece for a saw blade. A saw guide is proximate the saw slot, the saw guide arranged to position a saw blade in a cutting plane spaced apart from the workpiece for removing a segment of a bushing fixed to the workpiece relative to the first and second references.

A covering member made of a resin is integrally molded with a sensor substrate of a brushless motor in a circular saw by low-temperature, low-pressure injection molding. The covering member covers rotation detecting elements, a thermistor, resistors, and connecting portions (terminals) of lead wires that serve as electrically conductive portions conducting electric currents.
