US Patent 7219437 Laser guided work device

A laser guided work device including a work board having a work surface, a line producing laser projecting a line on the work surface, and a linear motion device engaging the laser to the work board. The linear motion device translates the laser relative to the work surface along at least one dimension. The line is oriented perpendicular to the at least one dimension such that the line moves relative to the work surface when the linear motion device translates the laser along the at least one dimension.
