Rush Gears Inc. (Fort Washington, Pa.) offers made-to-order custom and standard gears of all types, and can make them on a rush basis, in quantities from 1 replacement piece to 10,000-piece production runs. Production times range from the standard 2 weeks to the expedited options of 1 week, 72 hours, 48 hours and 24 hours. The company can manufacture from a drawing or from sample parts. The latter is done using reverse engineering, which reportedly replicates the part using REVWORKS and GearTrax Add-Ins to SolidWorks and the Faro Titanium Arm.
