Provided is a power tool capable of suitably fixing an auxiliary member to a base pedestal. The power tool has a base 30 having a sliding surface capable of sliding on a workpiece, and an auxiliary member 60 that is attachable to the base 30 and has a guiding surface 61. The power tool also has a wing bolt 33 and a leaf spring 35 as a pressing mechanism capable of pressing an extension part 62 of the auxiliary member 60. An operator can change a pressing force of the wing bolt 33 to the auxiliary member 60 by changing the position of the wing bolt 33 in a pressing direction. The leaf spring 35 applies a predetermined pressing force to the auxiliary member 60 even in the absence of the pressing force of the wing bolt 33 to the auxiliary member 60.

An adaptive cutting system is presented that facilitates cutting workpieces in new and different ways in a fun, easy, fast, accurate and safe manner. The system includes a benchtop having a grid of bench dog holes across its surface as well as a pair of table tracks embedded within its surface. An edge track extends around the benchtop and a pair of hinge members are connected to the edge tracks that also connect to a saw track that is movable between a raised and lowered position. The system also includes narrow rip stops, wide rip stops, bench dogs and a miter gauge all of which work in concert with the on-table features to facilitate on-table measurement and alignment of workpieces for performing cutting operations.

A jig apparatus to allow cutting straight lines in sheets of material using a portable tool with a cutting blade is disclosed. This apparatus includes a system or jig to hold the hold the portable tool in place, and keep it aligned at a specific angle, typically perpendicular but with angles other than perpendicular in some embodiments, to the edge of the sheet of material as the tool moves through the material, cutting it. In particular the portable cutting tool may be a circular saw.

Ring cutting jigs are disclosed that include a base; and a sliding brace. The base may include a platform and a pair of arms. A saw guide slot may be positioned within the base. Channels may be included within the base such that the sliding brace may move parallel to the channels with the assistance of pins that ride in those channels. The cooperation of the base and the sliding brace may act to secure a coil between the base and the sliding brace such that the coil may be cut into jump rings.
