Abstract:
Attachment ears in assembly with Johansson blocks for measurement of inclinations between spaced-apart conical surfaces of a workpiece being fabricated, comprising:an assembly of Johansson blocks of predetermined overall dimension, first and second ears, one disposed at each end of said assembly of Johansson blocks, said first and second ears having upper side surfaces with respective predetermined inclinations, means to retain the Johansson blocks and said ears in assembled relation, the sum of the inclinations between the upper side surfaces of the first and second ears defining an angular conical inclination to be provided on said workpiece, a gage having an indicator stylus, a stationary stylus and an indicator, said gage being positionable on said assembly of Johansson blocks and ears with its stationary stylus contacting the upper side surface of the first ear, and having its indicator stylus contacting the upper side surface of the second ear for movement thereof on said inclined conical surface to define an arc having the stationary stylus as a fulcrum to define an arc apex for setting an indicator of the gage as a reference to enable a reading of an angular dimension of the workpiece surfaces to determine the thickness of material to be removed therefrom.
