    Re: Buy or build a modern Bygrave slide rule

    Hi Sean

    Just find, on these pages, the words "Flat Bygrave".  Within them, you will find the images needed to create a Bygrave slide rule, albeit not cylindrical. Gary LaPook developed this.

    Further, Robin Stuart and I collaborated, within these pages, documenting the precise graphics needed to recreate an MHR-1 [Kriegsmarine Bygrave, currently in my possession].

    Further, it is certainly possible to recreate the mechanical tubes and pointers needed.  That will take a bit more doing, but others here have indeed done so.

    Brad

    Would like to contact [anyone] about buying/perhaps making a modern Bygrave slide rule. My intent is to use it for practical celestial navigation. Kind regards, Seán T. Rickard
