Are you sure you are using (or intending to use) a
sextant at minus 30 or minus 40 (the latter being the
same in degrees F and degrees C)?

Without really good head protection (which would make
using a sextant very difficult), my head hurt at that
kind of temperature sufficiently to stop me being able
to concentrate enough on any task as demanding as
taking a sight...let alone the risk to skin from
touching bare metal (and probably even from eyecup
rubber, too) ..

Are sextant calibrations valid at those levels?

But as I've lived in temperate and hot climates, with
only limited exposure to such extreme cold, I'm not as
tough as I should be.

Please tell us what drives you to do this!!
best regards, Keith Williams

PS - tinned wire doesn't "corrode" as quickly as
untinned, which has a life of maybe 10 years in
temperate salt-laden-air conditions (verigris builds up
and the wire loses its coppery-nature even inside
insulation and esp at connections, so resistance builds
up, which can stop yopur equipment or even create a
fire). But at minus 30 or so, I bet corrosion is a
totally different game
