Lee, thank you very much: On Thu, 11 Nov 2004, Lee Martin wrote: > Finally, might I note that many of the texts > on sextant maintenance (Bauer, > etc) refer to the "much loved" or "tortured" sextant syndrome. > They are > referring to the sextant being constantly fiddled with, adjusted, Yes, I read this. That's why I am trying keep it clean too... but the temptation to see "what is inside the drum" is strong:-) Sometimes some dark grease comes out of it in small quantities and I have to wipe the arc. Speaking of adjustment of SNO-T, this issue was already addressed by Lisa: the screw that adjusts the horizon mirror perpendicularity is a) over-sensitive and b) works in a funny way: you adjust it and it "plays back". Furthermore, I found that sometimes it apparently "plays back" even when I don't touch it. So unfortunately this mirror needs frequent adjustment; it does not "hold" well its adjusted position. It cannot be worn out: I bought my sextant "new" and everything looks new. It was in a factory wrapping, rubber parts covered with talc, etc. Alex.
