<p>Support structure (20) for a table saw blade assembly (26) includes a cast aluminum bracket member (38) with a rectangular opening (40) upon which is movably supported the saw blade assembly (26). The bracket member is formed with a cavity (46) for containing the saw blade (30) and a discharge chute (48) communicating with the cavity (46). A cover plate (56) encloses the cavity (46). On the other side of the bracket member there are stiffening ribs (52, 54) for reducing the vibration of the bracket member (38). The density of the stiffening ribs (52, 54) increases as the distance from the opening (42) decreases.</p> |
