ABSTRACT:
There is described a kerf guide and cautionary marker device for use with a power tool, particularly one employing a cutting type rotating tool, which guide and marker includes a groove cut into the table top of the apparatus. The groove extends linearly from the front edge of the tool opening towards the front edge of the table top. Disposed in the groove is a colored material, such as polystyrene, which has an exposed surface which can receive a scribe mark and/or cautionary instructions. The contrasting color between the inserted material and the surrounding table top alerts the operator to the fact that he is approaching the rotating tool. The operator aligns the guide mark on the work piece with the scribe mark on the material disposed in the groove and is thus able to properly position his work for the subsequent cutting operation.
If desired, a second groove, in line with the first groove, is disposed in the table top behind the tool and extends linearly from the rear edge of the tool piece opening to the rear edge of the table. Colored material is disposed therein, and the exposed surface of the material can have cautionary instructions marked thereon.
