I've tried my hand at making replicas of some famous slide rules. Not coincidentally, these are the one that were originally made with paper scales because I certainly don't have the skills to etch scales in celluloid.
My efforts have been made possible with assistance from Wayne Harrison, who builds the PostScript for rendering the scales. My part is building the hardware.
To date I've tackled Thachers, Logas and a Fuller. I'm open to suggestions.
