Abstract: A unitized saw guide and protractor assembly includes workpiece locator tabs whereby the assembly and workpiece can be hand-held safely for making a precision workpiece cut at a required angle by means of a saber saw. The same saw guide and protractor assembly is employed with a platform on which the assembly rests with its workpiece locator tabs engaged within slots of the platform which lock the assembly and platform together in a precision use mode to create a miter box, said tabs again contacting and positioning a hand-held workpiece for cutting. The saw guide and protractor assembly is used in a third mode with a vise equipped framing base as a miter machine where again the locator tabs engage a face of the workpiece to position the saw guide and protractor assembly with precision. A simplified highly versatile and very economical apparatus is achieved.
