Measuring thin work with dial gauge A attached to a special, inclined stand B for quick reading. The needle of indicator C is set at zero when measuring paint D is in contact with the face of the stand. To gauge work, raise point D by lever E. Place work F under the spindle and lower point to work by releasing lever E. The reading on the dial gives the exact thickness of the disk.
