  • scribing dividers ?

    From Richard Smith@21:1/5 to All on Mon Jul 21 13:48:27 2025
    Hello again all

    Is there such a thing as a "scribing divider" ?

    Useful for when working on "black" steel?
    Will cut-through / mark the mill-scale surface?

    Maybe about 10inch/250m to 12inch/300mm "legs".

    If I recall rightly I have seen dividers where each leg has a smallish
    about 3mm very hard steel/carbide cylinder ground to a point. Which
    can be demounted/unclamped and resharpened.

    If so, what are these known as?
    Not doing well looking in tool catalogues.

    Else - is the answer something else like dividers with a point at one
    end yes, but a chalk / soapstone at the swept end?

    Regards,
    Rich S

    Trammel points?


    I have a divider that has a sleeve with setscrew to hold a pencil or
    round soapstone . It's about 9-10 inches long .

    Trammel points yes.
    Forgotten about those. Yes they would be "the thing".
