Abstract: An indentation tool includes an installation axis, a radially oriented indentation axis, and a defined reserved space for an indentation site of a cylindrically-shaped structure, as well as a base for installing onto the structure, and an elongate punch for indenting it at its indentation site. The reserved space is spaced apart from the installation axis, and has the indentation axis passing through it. The base extends along the installation axis, and is configured for coaxial installation onto the structure, whereby its indentation site occupies the reserved space. The punch is spaced apart from the installation axis, and is supported by the base for movement along the indentation axis between a home position, in which the punch vacates the reserved space, and an indentation position, in which the punch, leading with an indentation tip, reaches into the reserved space to indent the structure at its indentation site.

Abstract: A center finding device for locating the geometric center of a workpiece having substantially parallel side surfaces including a pair of crossed arm members pivotally secured to each other by a tubular member with a marking pin received therein and secured at one end and in slidable-pivotal relation to a longitudinal slot in each of a pair of side guide arms whereby when the guide arms are moved into engaging relation with the parallel side surfaces of the workpiece, the crossed arm members are automatically slidable into a position with the tubular member being in a geometrically centered position with respect to the workpiece. In addition, the center finding device can be used in conjunction with an accessory for locating the geometric center of a workpiece having substantially non-parallel side surfaces.

Abstract: An apparatus includes a base plate, with a series of convex slots oriented in a clockwise array through the base plate, and a top plate including a clockwise array of concave slots, wherein the convex slots and concave slots are each of a predetermined number and each pair of overlying concave and convex slots includes a layout spool interconnecting the slots, wherein the spools are directed radially, interiorly, and outwardly of a central opening within the base plate and top plate. A graduated clamp ring mounted to the base plate is positioned exteriorly of the top plate, with a central knob mounted to the top plate to effect rotation of the top plate relative to the base plate.

Abstract: A method and apparatus for locating the intersection of the center of the web of a beam with a flat upper surface of an end cap of the beam. The apparatus has an upper portion that contacts the flat upper surface of the end cap and has ends that extend beyond the edges of the end cap. Arms that depend downwardly from the ends of the upper portion extend symmetrically toward one another. The upper portion has a predetermined point that is colocated with the axis of symmetry of the arms and an upper surface of the upper portion. The ends of the arms are separated by a distance that is greater than the thickness of the web. When placed over the end cap of a beam, the apparatus is turned about the axis of symmetry until the two arms contact opposing sides of the web, thereby locating the desired web center. The upper portion of the apparatus is preferably made from a transparent material.
