    Cathy, thank you for pointing this out. My error. Niobium *can* be
    cut with either the Jump Ringer or the All Metals Saw. I have three
    suggestions however. Lubricate - lubricate - lubricate. Because
    niobium is a gummy metal (as is soft copper), it is imperative that
    the coil be heavily lubricated to facilitate cutting. Titanium and
    any ferrous alloy (iron, plain steel and stainless steel) may not be
    cut with the Jump Ringer and so require the All Metals Saw. All other
    metals may be cut with either system. Ray Grossman Ray Grossman Inc.
