ABSTRACT:
A tool for measuring and filing the end gaps of piston rings to achieve a correct right angle end surface. The tool includes a support base and adjustable piston ring clamp. A ring stop adjustably determines the proper "gap" of the ring material to be removed while the support base provides a guide surface for a file to remove and dress the ring end surface.
