How does one use a cathead with a steady-rest to center a shaft with a rough surface (a rough casting or hot rolled steel)? When one dials in the cathead by adjusting the bolts on the cathead is the cathead being supported by the bottom 2 supports of the steady rest or is the steady rest closed and all 3 supports of the steady rest touching the cathead? Or is the cathead hanging out in space unsupported?
