    Re: Traditional navigation by slide rule

    >>I stumbled upon an Instructables page which mentioned that the May 2006 issue of Scientific American contained an article titled "When Slide Rules Ruled". It had a neat cut-and-fold diagram which allowed the reader to make his/her own slide rule out of paper and cellophane tape. The online version had the diagram attached as a pdf.<<


    I appreciate you highlighting the article in Scientific American.  It is interesting!!  I looked at that a while ago, and wasn't sure I trusted the qualtiy of reproduction well enough to use its scales for any but a quick and dirty homemade sliderule.  

    I am going to need a better feeling about the precision of what I produce before I am going to pay money for to have it created with a 3-D printing process.

    CorelDraw is (like Word, Excel and some other apps) capable of being programmed to create objects, or even whole documents, via Visual Basic for Applications (VBA).  I am intrigued by the idea of writing VBA code to produce a mathematically precise set of slide rule scales...but this is going to require me to grow both in my understanding of the underlying mathematical relationships between various slide rule scales, but also in my ability to translate math concepts into VBA code.

    I am a programmer by trade, but it is mostly in the area of document-management databases.  I have mostly used CorelDraw to reproduce clean, vector-based corporate logos to use in customizing software for my clients.

    If there are any VB or VBA programmers who would like to collaborate with me with the programming aspect of developing the Mark 1 Navigator's Slide Rule, please email me.
