Saw cutting guide

A device for trimming shingles adjacent a roof valley comprising:

• a cutting guide for guiding a blade of a circular saw through the shingles parallel to the roof valley at a predetermined offset distance from the center of the roof valley, the cuffing guide itself comprising:
• a mounting plate constructed and arranged to couple the cutting guide to a foot plate of the circular saw, the mounting plate having an aperture formed therethrough to permit the blade of the circular saw to pass through the mounting plate;
• a post extending from the mounting plate in general alignment with the blade of the circular saw;
• a base coupled to the post, the base having at least one lateral edge that is positioned at the predetermined distance from the blade, the at least one lateral edge of the base being substantially parallel to a cutting direction of the blade;
• and,
• at least one lifter block having an upwardly beveled leading edge, the at least one lifter block being secured to the cuffing guide at a selected side of the post immediately adjacent the base, the upwardly beveled leading edge of the at least one lifter block acting to bias shingles being cut by the blade of the circular saw away from the blade.

A modular cutting guide for a saw comprising:

• a mounting plate constructed and arranged to be coupled to a saw having a blade for cutting, the mounting plate having an aperture formed therethrough to permit the blade to pass through the mounting plate;
• a post removably coupled to and extending from the mounting plate in general alignment with the blade of the saw;
• and
• a base removably coupled to the post, the base having at least one lateral edge that is a predetermined distance from the blade, the at least one lateral edge of the base being substantially parallel to a cutting direction of the blade.

A cutting guide for a saw comprising:

• a mounting plate constructed and arranged to be coupled to a saw having a blade for cutting, the mounting plate having an aperture formed therethrough to permit the blade to pass through the mounting plate, the mounting plate being further constructed and arranged to support the cutting guide upon a surface;
• a post extending from the mounting plate in general alignment with the blade of the saw wherein the post is constructed and arranged to follow the saw blade into a kerf cut by the saw blade through a flexible material;
• and
• a base coupled to the post, the base having at least one lateral edge that is a predetermined distance from the blade, the at least one lateral edge of the base being substantially parallel to a cutting direction of the blade and wherein the at least one lateral edge touches an edge of the surface on which the cutting guide is supported.
