    Re: MHR1 reproduction

    Dear Dave and Robin,
    thank you very much for your respective messages.
    I had a look at the FORTRAN code that Dave kindly
    shared with the list- unfortunately my FORTRAN is not
    at all fluent and my understanding of the whole thing,
    well, only partly...(I am rather a programming dummy)
    Both your programs produce wonderful scales! Especially
    the reverse numbering in Robin's POSTSCRIPT is
    When making the reproduction I noticed that the tube
    diametres are within their specifications but vary
    What I am dreaming of is a program to produce an
    individual set of scales for two individually
    specified diametres. (logarithmic divisions matching
    by the arcs on both diametres)
    Maybe even pitch could be made a variable to perfectly
    match the tube lengths.
    The final, though least important, point on my wishlist
    would be a way to individually set the font... (to
    come closest to the original, most likely Futura...)
    I suppose these are lots of ideas that are hard to
    I have successfully compiled and run the FORTRAN code.
    (Which is designed to produce "flat bygrave" scales)
    And I think with some hints I could edit tube
    diametres/circumferences/pitch/font setting directly
    in any POSTCRIPT or FORTRAN code.
    I would be grateful for any help and ideas on how to
    best produce the helical scales needed to finish the
    best regards
