Saw guidance indicator comprises laser light emitter in saw blade plane to project light line onto workpiece below to keep cut straight

摘要

The flat beam of light (5) from the light emitter unit (3) coincides precisely with the plane of the saw blade (6) as placed on the wood workpiece (15). The emitter unit (3) is firmly seated (2) where arranged on the upper housing (1) of the saw so the projected line (16) of the light beam (5) forms a fine line along the work. The emitter itself comes in pen format and the emitter seat (3) is holed where it takes the unit (3). The top end of the seat (2) is threaded to take a regulating screw and nut or shoulder so as to clamp the unit and screw to the housing. The emitter unit (3) comprises a preferred laser source plus collecting lens coaxial with the light source, the unit itself rotatable as fitted.
