ABSTRACT:
An ovality gauge includes an elongated frame member carrying a roller support arm having a pair of rollers rotatably mounted to the roller support arm and spaced apart from each other. Preferably the rollers are adjustable to various positions. The ovality gauge also includes a moveable contact spaced from the pair of rollers, with the moveable contact and rollers in a plane parallel to the elongated frame member. The moveable contact is connected to an indicator means whereby movement of the moveable contact with respect to the pair of rollers is detected and indicates deviations of a cylindrical member contacting the gauge from perfect roundness.
