    Re: Sextant "heft"

    Frank-
    
    Perhaps "heavier" is a confusion with 'denser' materials, which might have
    greater thermal mass and as such change their dimensions more slowly when
    heating and cooling?
    
    I realize density and thermal stability are not directly dependent, but in the
    typical cases of "brass" versus "aluminum" versus "plastic", as you move from
    heavier to lighter materials in these three, aren't the heavier materials of
    these three also less likely to change during slight heat changes? (i.e. to give
    a misleading appearance that the heavier sextants were therefore more accurate.)
    
    Urban myths get off to great starts for lesser reasons.
