inboard yoke (4) faces upwards.
5. Support the joint (5) using the support (6).
6. Guide the joint (5) with one hand.
7. Keep turning the threaded rod (7) until the

8. Align the two clamping levers (1) opposite
the grooved yoke (2) so that the clamping
levers securely support the inboard yoke.

board yoke (2).

The inboard yoke can still easily be turned
