A golf club loft and lie calibration machine has a fixture with a cavity that exactly matches the back of the golf club head for clamping the golf club head. A pin with a tapered end is inserted into the bore of the golf club's hosel. The angular displacement of the pin is mechanically converted into two components of angular displacement which components are then converted to electrical signals. The electrical signals are processed to determine the deviations from the specified loft and lie angles. The deviation is used to activate hydraulic rams distributed around the fixture to bend the golf club head's hosel and bring the golf club back to specification.
