MULTIPLE SAW BLADE ADJUSTABLE DADO CUTTER ABSTRACT OF THE DISCLOSURE This invention relates to a dado cutting circular saw arrangment and more particularly to an arrangement comprising a pair of saw blades which are adjustable from a mimimum dado width cutting position wherein the blades are juxtaposed relative to a plane perpendicular to the rotational axis of the blades. A cam arrangement adapted to be interposed between the saw blades is employed for selectively adjusting the position of the blades to cut dados of varying widths. The cam arrangement causes the blades to pivot from their minimum dado position, juxtaposed to the plane, about adjacent peripheral pivot points in a manner that selectively adjustably positions the peripheral edges of the blades diametrically opposite from those adjacent pivot points outward relative to the plane and, thus, provide a range of dado cutting widths.
