This adjustable depth-stop for the backsaw aids in cutting accurate dadoes, rabbets, and half-lap joints. The idea is adapted from an antique saw I have. The stop is a couple of lengths of 3/8-in.-thick steel bar stock fitted with bolts on each end to tighten the stop on the blade at the desired setting. Alternatively, I suspect that the two bars could be made of wood if they were crowned slightly in the middle to clamp the entire blade length when tightened. If I have only a few dados to make I nearly always use this saw. It is easier and quicker than setting up the tablesaw with dado blades.
