Power Tool Construction Set

AKA Cordless Tool Construction Set - a modular construction set of motors, rotors, battery packs, and frames for making cordless drills, saws, cutters, and a wide range of other cordless and corded tools. The goal is to remove design-for-disposal tools from circulation, replacing them with tools that can be cannibalized and modified to achieve lifetime design - based on a common set of standard parts. This is the small scale version of the Tractor Construction Set.
