The tube bender of claim 11, wherein said first structure defines a first notch and said complimentary structure defines a tab that engages said first notch when said handle is moved to said first bending position. 13. The tube bender of claim 12, wherein said second structure defines a second notch and said complimentary structure defines a tab that engages said second notch when said handle is moved to said second bending position. 14. The tube bender of claim 1, wherein such operator pulls said handle in an axial direction away from said following member to move said handle into said unlocked position. 15. The tube bender of claim 1, wherein such operator pushes said handle in an axial direction towards said following member to move said handle into said unlocked position. 16. A tube bender comprising: a mandrel having a tube-receiving bending groove that extends arcuately at least 180 degrees about a bend axis, a forming member connected to said mandrel for coaction with said mandrel to effectuate at least 180 degree bending of a tube, said forming member having at least two bending positions defined thereon; a following member pivotally connected to said forming member defining a pivot point, said following member having a longitudinal axis defined thereon; a handle movable axially relative to said following member, said handle being associated with said following member to thereby permit said handle to rotate about said pivot point relative to said forming member; and engagement means for securing said handle in a locked position relative to said forming member when said handle is selectively moved to any of one said at least two bending positions thereby preventing relative movement between said handle and said forming member, said handle enables an operator to move said handle axially to an unlocked position to permit such operator to move said handle relative to said forming member between said at least two bending positions. 17. The tube bender of claim 16, wherein said following member is a shaft that is disposed within a cavity provided in said handle. 18. The tube bender of claim 17, further comprising a spring positioned between said shaft and said handle resiliently bias said shaft in a direction towards said forming member. 19. The tube bender of claim 17, further comprising a spring positioned said shaft and said handle to resiliently bias said shaft in a direction away from said forming member. 20. The tube bender of claim 16, wherein said engagement means comprises: a first structure disposed on said forming member defining a first of said at least two bending positions, a second structure disposed on said forming member defining a second of said at least two bending positions, and a complimentary structure disposed on said handle, said complimentary structure engages said first structure when said handle is moved to said first bending position thereby securing said handle in said locked position, said complimentary structure engages said second structure when said handle is moved to said second bending position thereby securing said handle in said locked position. 21. The tube bender of claim 20, wherein said first structure defines a first notch and said complimentary structure defines a tab that engages said first notch when said handle is moved to said first bending position. 22. The tube bender of claim 21, wherein said second structure defines a second notch and said complimentary structure defines a tab that engages said second notch when said handle is moved to said second bending position. 23. A tube bender comprising: a mandrel having a tube-rec eiving bending groove that extends arcuately at least 180 degrees about a bend axis, a forming member connected to said mandrel for coaction with said mandrel to effectuate at least 180 degree bending of a tube, said forming member having at least two bending positions defined thereon; a handle pivotally connected to said forming member; a release member pivotally connected to said handle; engagement means for securing said release member in a locked position relative to said forming member when said handle is selectively moved to any of one said at least two bending positions thereby preventing relative movement between said handle and said forming member, an actuation lever operably connected to said release member to enable an operator to actuate said actuation lever thereby moving said release member to an unlocked position to permit such operator to move said handle relative to said forming member between said at least two bending positions. 24. The tube bender of claim 23, wherein such operator pushes said actuation lever in an axial direction towards said following member to move said release member into said unlocked position. 25. The tube bender of claim 23, wherein such operator pulls said actuation lever in an axial direction away from said following member to move said release member into said unlocked position. 26. A tube bender comprising: a mandrel having a tube-receiving bending groove that extends arcuately at least 180 degrees about a bend axis, a forming member connected to said mandrel for coaction with said mandrel to effectuate at least 180 degree bending of a tube, said forming member having a socket in communication with at least two channels defining at least two bending positions in a first plane; a handle having a ball portion disposed in said socket and a shaft portion disposed in one of said at least two channels for securing said handle in a locked position relative to said forming member when said handle is selectively moved to any of one said at least two bending positions thereby preventing relative movement between said handle and said forming member; said handle being adapted to enable an operator to move said handle into a geometric plane different than said first plane to an unlocked position to permit an operator to move said handle relative to said forming member between said at least two bending positions. 27. A method of bending a tube comprising: positioning a tube in engagement with a tube-receiving bending groove of a mandrel, said mandrel having a first handle connected thereto; positioning an anchoring hook to maintain said tube in position relative to the bending groove; engaging a forming member with a surface of said tube opposite said bending groove in said mandrel, said forming member having at least two bending positions defined thereon and a second handle connected thereto; relatively moving said first and second handles toward each other to bend said tube at a first predetermined angle when said second handle is in a locked position relative to said forming member at a first of said at least two bending positions; actuating a release member to move said second handle in an unlocked position relative to said forming member without repositioning an operator's hand holding said second handle; while said second handle is still in said unlocked position, moving said second handle to a second of said at least two bending positions wherein said release member returns to said locked position; and relatively moving said first and second handles toward each other to further bend said tube at a second predetermined angle greater than said first predetermined angle. 28. The method of claim 27, wherein the first predetermined angle is about 90 degrees and the second predetermined angle is between about 90 degrees and about 180 degrees. ed, and an angle potentiometer that outputs an indication of the rotation angle. A rotatable arm is connected to the torque sensor. A stop prevents the arm from rotating past a rest position. At least one of the group consisting of the arm and the stop includes a magnet. The magnet causes a magnetic force that attracts the arm toward the rest position when the arm is at or near the rest position, simulating static friction. At least one elastic member, which may be a spring, urges the arm toward the rest position.
