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?

Alex.
