Remove the tie rod assembly from the steering rack. Place the inner ball end threaded stud through the hole of the Pin Spanner, engage the pins into holes in the ball joint socket, and install a nut on the stud to hold the socket securely in the pin spanner. Mount the pin spanner in a vice. Place the C-spanner (wrench) to engage slots in the ball nut, and unscrew anticlockwise to disassemble the ball joint.

Addendum November 10. 2013:
Mr. Nortier (British Tool Company) said he no longer has any, and as it had taken 8 years to sell the 10 sets he had made, there would not be any more.
