Phillip,

    I believe that you have your Foredom tools a bit mixed up. Foredom
    also makes a tool they call the "PowerGraver" which is their entry
    into the power assisted hand engraving tool field. There is another
    tool called "NGraver" which is also designed to work from a
    flexshaft motor. Both tools must be run from special flexshaft
    motors that put out lower RPMs than the common flexshafts that we
    all use at the bench. 

    Foredom makes it next to impossible to use their tool on anything
    other than the flexshaft that they designed it for. The there is a
    slot/tab that prevents connecting the handpiece to any flexshaft
    other than the one made to fit it. 

    NGraver will fit an "ordinary" flexshaft - but it is designed to be
    used with the gear reduction type flexshafts so seldom seen anymore.
    If you use it on a "regular" flexshaft you will destroy it in a
    short time. 

    Both tools are basically reciprocating mechanical hammers. They are
    the most economical entry level power assisted hand engraving tools. 

    The disadvantages to these two tools are in the awkwardness of the
    handpieces and the bulky flexshaft, and the fact that either of them
    - when run for long periods of time to do stippling for example -
    will fail & have to be rebuilt. 

    Both tools will work to get you started in hand engraving and bright
    cut, pave, and flush stone setting. After you become proficient you
    can move on to one of the air driven power assisted tools by Lindsay
    or GRS. 

    All of these tools - Foredom, NGraver, GRS, and Lindsays are
    available for students to try in my workshops. I do not sell
    tools...
