ABSTRACT:
A simple miter guide uses planar sheet material to define an overlay panel, a saw guiderail and depending lumber guides and spacers which orient the lumber at a predetermined angle relative to the saw blade and space the guide over an underlying surface. The guide is designed specifically for construction lumber such as two-by-fours and two-by-sixes, and is used by placing the guide on a flat surface, and feeding the lumber into the guide from the back until it is properly aligned for the saw cut. The guide and lumber can be aligned to establish an orthogonal square-cut, or an angle-cut such as 45 degrees. A saw guiderail guides the end of the saw foot as it moves across the saw support raceway, spacing the sawblade adequately from the guide to prevent damage, and permitting an angled undercut to be made. Means to mount the guide to an underlying surface are provided, although unmounted operation is useful too.
