Came upon the above referenced post, and your add on comments, thoughts, references to the Navigator's Sliderule. Has there been and progress or additional developments thereon? Regarding slide rules, prior to retirement, I did not much use the things, insufficient accuracy potential for the pipe fabrication calculations I was involved in, we had to give fabrication dimensions to 1/16". No way to obtain that degree of accuracy with a slide rule, we used Smoley's Tables, this was before electronic calculators.

Anyhow, in the intervening years, I have accumulated a box full of stick and circular slide rules, the old fashioned stick slide rules were and still are, quite amazing devices. By the way,  the Log-Log scales have remained a puzzle to me also. Anyhow, please keep me in mind regarding any developments in the Navigators Slide Rule project. Thanks and happy holidays.
