Abstract:
1. A tool to hone the outer-diameter of a cylindrical work-piece, comprising: a tool body comprising a hollow cylinder; an abrading assembly within said body comprising: an abrasive belt, being a sanding belt or similar abrasive device, constrained within said body; a plurality of restraint arms, each in a U-shape, within said body, whose ends pass radially outward through said body, with their lengths arranged along the axial length of said body; wherein said belt is radially disposed about the inside of said body in a triangular shape with respect to the end of said body; said body having a rectangular slot along the axial length of said body; said belt having two parallel ends exiting radially through said slot; a rectangular clamp block whose length is coincident with said slot, comprising two clamping halves forced together with screws or other ordinary mechanical devices; said two parallel ends clamped together between said halves; said block with said two parallel ends clamped therein in contact with the outside of said body so that said ends cannot move inward through said slot; a stop at each end of said arms; an extension spring about each end of said arms between each of said stops and the outer surface of said body; wherein compression of each of said springs against said body forces each end of said arms radially outward from said body, causes said arms to apply radial force to the inside of said belt such that said belt is in tension, and the contact between said block and said body is in compression; wherein said belt is restrained in to a triangular shape having three sides by said arms and said slot.
