UltraLog Scale Dvelopment

After scale design was completed, a Delphi program was developed to generate the scales for the two sides of the slide rule - front and back. It was a very crude tool which was not meant to produce a final result. The purpose was to build a quick cardboard model using screen printouts and to try the scale arrangement in actual calculations.

 

These are the screen shots used for the model - you can print them and construct your own slide rule.
