Homemade Brake Rotor Tube Bender Diagram - DIY Bender Design Schematic

This document is a 3D CAD rendering (appearing to be a SketchUp model) illustrating a homemade tube bender design built from two brake rotors. The drawing shows a long straight tube passing across a pair of stacked brake rotors, with a curved 'wrench' arm engaging the rotor. Three text callouts explain the construction: the two rotors are bolted together with six grade 8 bolts and require no other modification; U-bolts secure the tube to the curved 'wrench' lever arm; and teeth on the end of the wrench clamp into the cooling vents of the rotors to provide leverage. A reader can learn the basic concept of this DIY bender: the stacked rotors act as the bending die/form, the tube is held to a lever arm via U-bolts, and the lever anchors itself in the rotor cooling vents so the tube can be bent around the rotor circumference. The document contains no dimensions, part numbers, vehicle applicability, torque specifications, or year information, it is purely a conceptual schematic with brief annotations. It appears to be one page of a multi-page set (a companion file named 'bender.jpg' exists in the same album).
