1. A table saw comprising:
a base assembly having a base structure and generally vertical front, back, left and right side walls, and being configured to retain an undercarriage assembly for driving a rotatable blade; a table top assembly supported by said base assembly and having a top surface with an opening through which the rotating blade can extend; an undercarriage assembly including a motor, said undercarriage assembly being mounted within said base assembly and below to said table top assembly and being configured to adjust the vertical and angular position of the blade relative to said table top assembly, said undercarriage assembly further comprising:
an undercarriage frame and cover positioned within said base assembly and including a plurality of side walls that are connected to form a narrow housing within the base assembly configured and sized to surround an installed blade, the side walls including upper portions and lower portions, the upper portions defining an open top for the narrow housing from which the blade can extend to the opening in the top surface of the table top assembly, the lower portions defining an open bottom directly under at least a portion of the blade, said frame having an upper pivot connection for adjusting the angular position of the blade and being configured to have said motor slidably mounted therein to adjust the vertical position of the motor and blade; anda removable port structure received within said base assembly and removably attached to said housing, said port structure having an elongated body that extends across said open bottom of said narrow housing under said blade and includes a bottom wall and side walls that extend upwardly from a perimeter of the bottom wall to the lower portions of the side walls of the housing to enclose said open bottom of said housing, said bottom wall and said side walls of said port structure defining a receiving chamber with an open upper portion communicating with the inside of said housing, said elongated body including an outlet port in communication with said receiving chamber and configured to be connected to a vacuum source; wherein said elongated body of said port structure is configured to collect dust and debris which may accumulate within said housing when said motor is not operational, wherein said undercarriage assembly has a pair of spaced apart elongated support surfaces configured to engage a pair of complementary rails of said port structure, said port structure being selectively slidably attachable and removable from said undercarriage assembly, and wherein said port structure has an elongated rail on each side of said elongated body which is configured to engage said support surfaces of said undercarriage assembly. |
