Hammer ball diagrams Materials: Wood; Dimensions: Millimeters 1. Disk The axis of rotation must be the same as the center of the horizontal disk (to avoid eccentricity). The difference between the two cursor readings should be equal to 180°. 2. The horizontal axis of the vertical plate must be orthogonal to the axis of rotation of the instrument—the horizontal axis is fixed. Turn the vertical plate to align the leveler. Rotate the dial to rotate the 180° level. Is any position centered? 3. The cross hair must be horizontal with the direction of gravity. Fix the vertical plate. The horizontal plate is aimed at the distant point with the center of the reticle to rotate the observation tube up and down. At this time, if the image of the target point is fixed on the vertical wire, the vertical wire
