A clamp lathe dog should be balanced by making the straight jaw much wider, which gives the desired weight for balancing the opposite jaw that enters the face plate of the lathe. One can readily see the proportions in Fig. 143, which are just as tasty as those of an unbalanced clog. In turning small slender work which must revolve rapidly, the value of the balanced dog will be appreciated.

With large work it does not make any material difference.
