Hello Susan,

    If you mean the same technique with a larger mandrel but still cut
    with the #8/0 blade then I'm sure the answer would be yes, up to a
    point. When your jump ring's inner diameter starts to get large --I'm
    guessing but I'd say 5mm or more-- then the coil doesn't snug itself
    around the unturned mandrel as tightly and you start getting slop
    again while you're cutting. 

    If on the other hand you meant heavier wire for the coil then I'm
    sure there'd be no problem other than the fact that your sawing would
    get more laborious because you are working that teeny #8/0 blade
    through more and more metal. 

    I'd done a little test with a larger mandrel (4mm) and basically
    found that the technique is sound as long as you find the "right"
    match between your winding and your cutting mandrels. It appears to me
    as if "right" means large enough to hold the coil nice and snug but
    not so large that it's a pain to get the coil on without stretching
    the rings to a larger size in the process. 

    Frankly I'd guess that if your coiling mandrel is 5mm or more you're
    probably better off just wrapping the coil in painter's tape in order
    to keep it snug and forget about the hassle of making the second,
    slightly larger cutting mandrel. 

Cheers,
Trevor F.
