A tool to measure the radial stacking angle of a cylindrical blade comprises a base configured to indicate a radial direction of the hub, a component slidable over the blade and configured to indicate the stacking direction of the cylindrical blade, reference elements to provide a reference scale, a setting element configured to set the position of the component with respect to the base, a marker element configured to indicate the magnitude of the angle between the stacking direction and the radial direction using the reference elements; the angle corresponds to the radial stacking angle. |
