    This reminds me of discussions in the Yahoo slide rule group on the
    Ultralog, "the most advanced general engineering slide rule ever
    produced." Its original designer died, but somebody else took over. A
    major issue was what manufacturing technology to employ. However, there
    has been no news for a long time, so I'm not sure if the project is
    still alive.

    It may be worthwhile to contact the current designer, or even browse the
    Yahoo message archive. Last I knew, you had to join the group to get
    access, but that was free.
