    Have you checked your waxes for air bubbles? I had a similar problem
    with sterling, only on one certain wax design. Turned out that the
    sprues were getting bubbles in them during the wax injection.
    Adjusting the wax pot temp and pressure solved the problem. I hope
    yours is as simple to fix!
