Abstract: A threading tool, such as a tap or die holder, is configured to be driven by a generic wrench. The tool is provided with a wrench-engageable surface, such as a faceted cylindrical surface, or a cylinder with a polyhedral cross-section perpendicular to its axis. A outwardly extending peripheral flange, downward from the wrench-engageable surface, contacts and allows an open-backed wrench to exert downward force on the tool. A inwardly extending peripheral groove, downward from the wrench-engageable surface, allows a wrench to insert a holding device into the profile of the tool to hold the wrench and tool together. The holder may have a collet that activates the holding function by moving along the axis of the holder, but the collet is prevented from rotating about the axis of the holder. The collet may have a wrench-engageable surface. A collar, threaded to the holder, moves the collet.

Abstract: A fixture for use with a saw table or router table for supporting an elongated workpiece used in conjunction with the rip fence mounted on the table. The fixture has a first rail pivotally connected at one end to one end of a second rail. The first rail is adapted to be guided along the rip fence, while the second rail can be pivoted to an angular positions relative to the first rail. The second rail has a longitudinal guide surface that can assume a plurality of angular positions relative to the rip fence. A head end retaining mechanism is connected to one of the rails for holding one end of a workpiece at a fixed point relative to the longitudinal guide surface. A tail end retaining mechanism is connected to one of the rails for maintaining the opposite end of a workpiece at a fixed point relative to the longitudinal guide surface. The tail end retaining mechanism is adjustable vertically and horizontally toward and away from the longitudinal guide surface.
