Dear all,

    I occasionally find myself needing springs to complete my designs,
    and at the moment an unusual project to make a disassembling martini
    glass* out of glass and silver** is floundering as I need a very
    specific type of spring to make the stem work. 

    In the past I have wound my own, badly, from piano wire, but this
    project needs something a bit more special, possibly even as exotic
    as superelastic Nitinol or titanium. Have any of you had anything
    similar made up, and if so could you recommend a supplier? I have
    done the usual internet searches and the odd RFQ, but as yet have had
    no joy from the more obvious sources. 

    Regards

          * Though all martini glasses are prone to disassembling, the
          beauty of this one is that it reassembles as well. 

          ** Yes, I may have been unduly influenced by too many martinis
          when I came up with the idea.
