Usually it is more convenient to apply turnbuckle at BB, maximally contracted, and to apply hooked turnbuckle at AA, expanded sufficiently to engage diverging shafts. Then this same turnbuckle at A A is contracted until clamps are parallel or nearly so; after this, expansion of turnbuckle at BB can begin. b) The Lowman clamps constitute levers; the turnbuckle at B is the fulcrum, the resisting soft parts at C, and the turnbuckle at A, balance each other.

To prevent thisoccurrence, it is necessary (a) to place the turnbuckle as close down to thebone as possible; (b) to keep the two clamps parallel to one another byusing a second turnbuckle armed with hooks (Fig. 34). As the turnbuckleclose to the bone forces the clamps apart, the upp
