The method includes securing the fixture to a mounting support, activating a fluid pressure mechanism to release a clamping bar holding the wrenches to a plate member, mounting the wrenches to the fixture, and releasing the clamping bar which is then biased back to its original position so as to clamp the wrenches to the fixture. The fixture is than moved to the jig for the grinding operation.
