[Jewelry making - Article 00608] - [Orchid] Modulgrav inside ring engraving issue

    We acquired a used Modulgav engraving machine a while back, and have
    just been starting to get familiar enough with it to use it
    reliably. While we have some other ideas for the thing, the main
    opportunity at this point seems to be offering inside-ring engraving
    to the people who are commissioning rings. 

    This is turning out to be a problem, though, because the inside-ring
    module is balky. After we'd gotten it, in our first serious trial of
    the thing, it stuttered enough on the horizontal movements that it
    ended up being unusable. At this point we sent it to Gesswein to have
    it reconditioned, which they did, and it seemed to be working at
    first... but now it's stuttering again, and again on the horizontal
    movements. 

    Now, working the control back and forth like a pendulum for a while
    moderated the stuttering enough that we could use it, but I'm pretty
    concerned about what's going wrong here, and how we might be able to
    deal with it. My best guess at the moment is that the lubrication,
    whatever it is, is congealing on the bearings. If that's the case,
    working it regularly ought to be able to keep it usable- but I don't
    KNOW that's the problem or the best solution! 

    So- anyone have a Modulgrav with an inside-ring attachment and can
    offer me some pointers to get it and keep it working smoothly? 

    Any pointers for any of the other attachments will also be very
    welcome, and sincerely appreciated. 

    I guess if we end up having to replace the thing with a dedicated
    inside-ring engraver, we could consider it... but there's enough
    other stuff we want to do for which the Modulgrav looks like a good
    choice that I'm reluctant, especially since we don't really have
    enough space for yet another engraving machine..! 

    Thanks much for any advice and tips!
