To maintain the finished sanded surface of the cut perpendicular to a specified axis of the work piece, the axis of rotation of the saw blade is tilted to place a radial of the cone shaped abrasive surface orthogonal in three axis to the direction of saw cut being made. ## Claims ### Claim 1 Apparatus for cutting and finishing a surface of a work piece, having a longitudinal axis which surface is perpendicular to the longitudinal axis of the work piece, said apparatus comprising in combination: (a) a rotary saw blade having teeth disposed along its perimeter for making a cut in the work piece to form the surface on the work piece, said rotary saw including one and an other side and a cone shaped surface defining a shallow cone angle and disposed on the one side; (b) abrasive material disposed upon the cone shaped surface of the one side for finishing the surface formed on the work piece; and (c) an arbor for supporting said rotary saw blade, said arbor having an axis of rotation offset from the longitudinal axis of the work piece by the cone angle. ### Claim 2 (depends on 1) The apparatus as set forth in claim 1 wherein the cone angle is in the range of 1-3 degrees. ### Claim 3 Apparatus for cutting and finishing a surface of a work piece which surface is perpendicular to a longitudinal axis of the work piece, said apparatus comprising in combination: (a) a rotary saw blade having teeth disposed along its perimeter for making a cut in the work piece to form the surface on the work piece, said rotary saw including one and an other side and a cone shaped surface defining a shallow cone angle and disposed on the one side, the other side of said rotary saw blade being planar; (b) abrasive material disposed upon the cone shaped surface of the one side for finishing the surface formed on the work piece; and (c) an arbor for supporting said rotary saw blade, said arbor having an axis of rotation offset from the longitudinal axis of the work piece by the cone angle. ### Claim 4 (depends on 1) The apparatus as set forth in claim 1 wherein the other side of said rotary saw blade includes a depressed cone shaped surface. ### Claim 5 (depends on 1) The apparatus as set forth in claim 1 wherein said teeth are offset. ### Claim 6 (depends on 1) The apparatus as set forth in claim 1 wherein said rotary saw blade includes a central roundel and wherein said arbor includes attachment means for securing said roundel to said arbor. ### Claim 7 (depends on 1) The apparatus as set forth in claim 1 wherein said rotary saw blade includes an annular band and wherein said teeth are formed in said band, said band being radially aligned orthogonal to the axis of rotation of said rotary saw blade. ### Claim 8 (depends on 1) The apparatus as set forth in claim 1 wherein said abrasive material defines a concentric band disposed on said cone shaped surface. ### Claim 9 (depends on 1) The apparatus as set forth in claim 1 wherein said abrasive material comprises sandpaper. ### Claim 10 (depends on 1) The apparatus as set forth in claim 1 wherein said abrasive material comprises a composition of abrasive material adhered to said cone shaped surface. ### Claim 11 Apparatus for cutting and finishing a surface of a work piece, said apparatus comprising in combination: (a) a rotary saw blade having teeth disposed along its perimeter for making a cut in the work piece to develop the surface of the work piece, said rotary saw blade having an aperture at its center and including one side and another side; (b) abrasive material for finishing the surface cut in the work piece by said teeth, said abrasive material being disposed upon the one side to define a shallow cone shaped surface extending radially inwardly for a substantial distance from a location radially inwardly from said teeth and defining a shallow cone angle with respect to a plane extending radially from the axis of rotation of said saw blade; and (c) an arbor engaging the aperture of said rotary saw blade for supporting said rotary saw blade and having an axis of rotation offset from perpendicular to a plane defined by the other side of said rotary saw blade by the cone angle. ### Claim 12 (depends on 11) The apparatus as set forth in claim 11 wherein the cone angle is in the range of 1-3 degrees. ### Claim 13 (depends on 11) The apparatus as set forth in claim 11 wherein the other side of said rotary saw blade is planar. ### Claim 14 (depends on 11) The apparatus as set forth in claim 11 wherein the other side of said rotary saw blade includes a depressed cone shaped surface. ### Claim 15 (depends on 11) The apparatus as set forth in claim 11 wherein said teeth are offset. ### Claim 16 (depends on 11) The apparatus as set forth in claim 11 wherein said rotary saw blade includes a central roundel and wherein said arbor includes attachment means for securing said roundel to said arbor. ### Claim 17 (depends on 11) The apparatus as set forth in claim 11 wherein said rotary saw blade includes an annular band and wherein said teeth are formed in said band, said band being radially aligned orthogonal to the axis of rotation of said rotary saw blade. ### Claim 18 (depends on 11) The apparatus as set forth in claim 11 wherein said abrasive material defines a concentric band disposed on said cone shaped surface. ### Claim 19 (depends on 11) The apparatus as set forth in claim 11 wherein said abrasive material comprises sandpaper. ### Claim 20 (depends on 11) The apparatus as set forth in claim 11 wherein said abrasive material comprises a composition of abrasive material adhered to said cone shaped surface.
