The fixed-base router includes a base assembly and a cylindrical motor housing. The base assembly has a tubular member defining a vertically disposed inner cylindrical surface with two longitudinally extending support ribs. The tubular member has a longitudinal slot or opening between a pair of adjacent inner projections. Only the two ribs and the inner projections engage the cylindrical motor housing when the base tubular member is clamped to the cylindrical motor housing. The two support ribs and the slot are substantially equally spaced from each other. Another set of ribs prevents tilt when the tubular member is in an unclamped condition, and a deflection limitation rib is provided to prevent excessive deflection of the base tubular member when the clamping force is too high.
