ABSTRACT:
A guide arrangement for portable power saws is made up of a guide plate adapted to be placed on the work and a stand plate fixed to the saw. The guide plate possesses a raised rail running in the feed direction of the saw. In use, the saw with the stand plate is placed on the guide plate so that a socket in the stand plate fits round the rail and the stand plate may then be moved along the guide plate on the rail, the guiding section straddling the rail and guiding the stand plate on the rail. The stand plate is fitted with a backlash limiter having an operating part acting against the side of the rail for reducing play between the rail and the stand plate. This means that the saw is guided in the length direction parallel to the rail of the guide plate and it is possible for straight cuts to be sawn with a high degree of accuracy without any danger of the saw running askew.
The backlash limiter may take the form of a spring loaded member or one driven by a screw or threaded rod. Alternatively the member may have a slot to allow adjustment thereof in relation to the rail.
