    Re: Traditional navigation by slide rule

    Life crowded out slide rule work.  I did all the work I did do at a time when my job involved writing computer code, and then having to let it run for 3 to 5 hours to know whether my changes were effective or not.

    I have set my retirement for April 30.  Cleaning out the basement, to facilitate moving to a smaller house, is the #1 priority, along with taking ballroom dancing classes with my wife.  But I do expect to finish up the slide rule project as well.

    I did all the work on the scales.  I will get a friend to help me develop the actual engineering-type drawings to take to the machine shop.

    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.
