Abstract: A saw gauge for quickly and accurately measuring lengths of boards to be cut with a cross-cut saw is disclosed. The gauge includes a series of two or more bar segments having a flat base portion adapted for mounting on a cutting table in line with a guideway or fence also mounted thereon and a plurality of raised ribs of predetermined width projecting upwardly from the base portion and being spaced apart by channels of predetermined width. An elongated pivot pin extends the length of the segments behind all of the ribs in each segment except an end one of the ribs, which extends rearwardly behind the remaining ones of the ribs in each segment and contains a hole therein through which the pin projects for support.
