Abstract:
A PVC-pipe-end smooth-surfacer comprising:a reamer cylinder having an internal periphery of a pipe-fitting end that fits slidably on an outside periphery of a predetermined PVC pipe having a jagged end to position the reamer cylinder concentrically on the outside periphery of the PVC pipe; a cylinder base having a first cylinder wall proximate a drive end of the reamer cylinder and a second cylinder wall intermediate the drive end and the pipe fitting end of the reamer cylinder, each cylinder wall having a cylinder bearing; an insertion spring positioned intermediate the first cylinder wall and the second cylinder wall; a cutter and grinding shaft that is rotatable and slidable linearly in the cylinder bearings with the shaft being concentric to an axis of the reamer cylinder; in combination, a first cutter wheel selectively affixed to a cutter and grinding end of the shaft to cut jagged edges of the pipe and second smoothing surfacer wheel selectively affixed to the cutter and grinding end of the shaft to smooth the surface of the pipe; the first cutter wheel having a cutting element and the second smoothing surfacer wheel having a smoothing element both being oriented a predetermined angle from an axis of the cutter and grinding shaft; and a drive coupling on the drive end of the cutter and grinding shaft.
