Abstract
A multi-beam tool is disclosed which can perform square, plumb, and level function which may be required in a construction environment. The tool can generate in a preferred embodiment up to five orthogonal beams with two beams being plumb and three beams being leveled. Combinations of two level beams, or a level and a plumb beam in orthogonal arrangement can produce a square alignment set of beams. The tool includes in a preferred arrangement a self-leveling pendulum to which a laser and quad-mirror arrangement is secured. The self-leveling pendulum is damped in order to allow the tool to settle down and provide alignment after the tool is positioned as desired. The quad-mirror, the magnetic damping, and the coiled wire allowing power to be provided to the laser assembly, each separately, and also in combination, provide for a compact tool.
