    Bygrave slide rule , o-rings, circular slide rules
    From: Bruce Hamilton
    Date: 2008 Jun 14, 23:39 -0700

    I was reading in the archives about the Bygrave slide rule, and one of
    the posts mentioned that there was a link to printouts of the scales,
    but I never found the link. If some one has it, could they send it to
    me. As well, Geoffrey said he built one, and I would love to see
    pictures of his project.  I might mock one up in cardboard if I can get
    the scales.If I ever get around to mastering Solidworks, I could get one
    made on a rapid prototyping machine. Perhaps Geoffrey has the g-code?
    
    I also remembering someone was looking for seals in an odd size to
    repair an aviation sextant. Check out Rocketseals.com. I buy from them
    and they have a huge selection.
    
    Some one was looking for circular slide rules and I found a page with a
    huge selection.http://www.sphere.bc.ca/test/circular.html
    
    
    
    Thank you
