    Yrvind folding sextant
    From: Paul Saffo
    Date: 2008 Nov 25, 14:09 -0800

    And here is a pic of another of Sven's sextant ideas, a folding
    sextant made from a caliper and wooden protractor, taken by a friend
    recently.The idea is that by using a linear scale it is easy to make
    and then one reduces the measurements by either a table or calculator.
