    Are you sure that the wormscrew is made of alluminium?
    I never disassembled the trommel, but I tried to look
    inside (you can see part of the worm through the slit
    in the trommel on SNO-T when the
    sextant is set on
    the minimal or maximal angle). My impression is that it does not look
    like aluminium (it is dark yellow).

    Contrary, so far I am happy with my SNO. Especially after
    both Freiberger and Cassens-Plath independently confirmed that its arc
    is indeed perfect. (Yes, I've obtained two certificates, from both
    of them, this summer, in addition to my original Russian
    certificate which I did not trust much:-)

    Have you used it on a small boat?
    What size boat?
    If yes, could you share with me your experience:
    1. Where exactly
    did you store the Celestaire plastic box on the boat?
    2. Are you always able to catch the high sun
    when the waves and wind are strong, without detaching the scope?
