    Interesting. 

    Someone gave me a micromotor along with the box and all the
    attachments to diamond-cut jewelry (not something I'm very
    interested in doing!) I'll give it a try for this (above) 
application. 

    BTW, I bought a Diprofil on ebay and, for certain applications, it's
    a very good jewelry tool. 

    This is the model I bought (I paid considerably less than this
    person is asking.) Apparently the company no longer makes this model.
