An apparatus for testing flatness includes a main fixture defining a longitudinal axis along a direction between a base of the main fixture and a testing end of the main fixture. A gimbal is slidingly engaged to the main fixture to slide in a direction along the longitudinal axis. A biasing member is axially between the base and the gimbal. Three rotating arms are mounted to the testing end of the main fixture. The rotating arms and gimbal are configured to affix a test article in the testing end of the main fixture flat with respect to the three rotating arms to establish a datum plane for flatness testing of the test article.
