Abstract
A grindstone type of cylinder ridge remover to be used in conjunction with an electric drill for removing the ridge on the cylinder walls of piston type engines. The plate body of the cylinder ridge grinder rests on the top of the cylinder wall and is rotated by hand around the top of the cylinder wall, while an electric drill turns a grindstone by way of a shaft compatable to the chuck of the electric drill thus grinding away the ridge very effectively and very easily. The distance between the bottom of the body plate edge and the bottom of the grindstone, the depth into the cylinder which is to be ground, is regulated very exactly by an outside threaded sleeve bearing in complete control of the grindstone shaft being screwed up and down inside a threaded hub fixed to the body plate. The grinding depth position is locked by a thumb screw thru the hub side wall and against the outside of the sleeve bearing. Any normal size cylinder can be ridge ground without any complicated adjustments, very accurately since the stone cuts very gradually, and with little effort; a new, practical, the economical way of removing cylinder ridges.
