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 brilliant. When making the reproduction I noticed that the tube diametres are within their specifications but vary slightly. 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 implement. 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 reproduction! best regards Wolfgang Am Dienstag, 13.
