The invention claimed is: 1. An apparatus for cleaning a portion of a tubular member, comprising: a platform; a motor operatively connected to a shaft; a first sliding base driven by the shaft to revolve generally parallel to the platform; a first pinch thumb, including an outer surface, mounted onto the first sliding base to revolve with the first sliding base; a first pinch finger, including an outer surface, mounted onto the first sliding base; and an adjustable clamp arm adapted to secure a tubular member above the platform and adjacent the first sliding base; wherein, after the adjustable clamp arm secures the tubular member above the platform, the first sliding base revolves to urge the first pinch thumb to move radially outward to contact an inner diameter of the tubular member and the first pinch finger moves radially inward to contact an outer diameter of the tubular member. 2. The apparatus of claim 1, further comprising a slide rail mounted onto the platform and slidably attached to the first sliding base for revolving with the first sliding base. 3. The apparatus of claim 1, further comprising a second sliding base that revolves xvith the first sliding base. 4. The apparatus of claim 3, further comprising a second pinch thumb, including an outer surface, mounted onto the second sliding base. 5. The apparatus of claim 1, wherein the first sliding base includes a spring hook for connecting a spring to the first pinch finger to resiliently urge the first sliding base towards a center of rotation of the slide rail. 6. The apparatus of claim 1, further comprising a revolution counter for counting a number of first sliding base revolutions. 7. The apparatus of claim 1, further comprising a tube edge detector for detecting the presence or absence of the tubular member within the apparatus. 8. The apparatus of claim 1, further comprising a clamp micro switch for ensuring that the clamp arm secures the tubular member. 9. The apparatus of claim 1, further comprising an abrasive material held on the outer surface of the first pinch thumb. 10. An apparatus for cleaning a portion of a tubular member, comprising: a motor operatively connected to a shaft; a slide rail operatively connected to the shaft and situated to revolve above a platform; a first sliding base slidably attached to the slide rail for revolving with the slide rail; a second sliding base slidably attached to the slide rail for revolving with the slide rail and the first sliding base; a first pinch thumb, including an outer surface, mounted onto the first sliding base; a second pinch thumb, including an outer surface, mounted onto the second sliding base; an abrasive material held on the outer surface of each of the first pinch thumb and the second pinch thumb; a first pinch finger, including an outer surface, mounted onto the first sliding base; a second pinch finger, including an outer surface, mounted onto the second sliding base; an abrasive material held on the outer surface of each of the first pinch finger and the second pinch finger; and an adjustable clamp arm adapted to secure a tubular member above the platform; whereby when the slide rail is revolved, about the longitudinal axis of the tubular member, the first sliding base and the second sliding base will move radially outward such that the first pinch thumb and the second pinch thumb are moved radially outward to contact an inner diameter of the tubular member and the first pinch finger and the second pinch finger will be moved radially inward to contact the outer diameter of the tubular member. 11. The apparatus of claim 10, wherein the abrasive material held on the outer surface of the first pinch thumb abrades the inner diameter of the tubular member. 12. The apparatus of claim 10, wherein the abrasive material held on the outer surface of the first pinch finger abrades the outer diameter of the tubular member. 13. The apparatus of claim 10, further comprising a first counterweight slidably attached to the first pinch finger and a second counterweight slidably attached to the second pinch finger. 14. The apparatus of claim 10, further comprising an alligator clip adapted to secure the abrasive material to the first pinch finger. 15. The apparatus of claim 10, wherein the first sliding base includes a spring hook for connecting a spring to the first pinch finger to resiliently urge the first sliding base towards a center of rotation of the slide rail. 16. A method for edge cleaning a portion of a tubular member, comprising: clamping a tubular member within an adjustable clamp arm; attaching slidably a first sliding base to a slide rail; mounting a first pinch thumb onto the first sliding base; mounting a first pinch finger onto the first sliding base; and revolving the first sliding base; whereby the first sliding base will urge the first pinch thumb to move radially outward to contact an inner diameter of the tubular member and the first pinch finger will move radially inward to contact an outer diameter of the tubular member. 17. The method of claim 16, further comprising attaching slidably a second sliding base to the slide rail. 18. The method of claim 17, further comprising mounting a second pinch thumb onto the second sliding base. 19. The method of claim 16, further comprising abrading the inner diameter of the tubular member. 20. The method of claim 16, further comprising abrading the outer diameter of the tubular member.
