Re: M_Boats: remove the compass for the winter?

[Gilbert Landin]

Here and I thought they were filled with something like cooking oil. My 
compass had somehow lost fluid. I had read somewhere that west marine 
stocked compass oil, so I went and asked the salesman they order it in some 
large quanitity and was very expensive ( I only need about 5oz) so I am 
still running low.

Hi Doug,
Back  - many years ago - pre WWII, when I worked at Kollsman Instrument
Company, our aircraft compasses were filled with a highly refined
kerosene.
I also recall US Navy compasses (and lifeboat compasses) at that time
were filled with ethyl alcohol, which troops discovered, and used
inappropriately...................
My guess is that a compass should stand a -10 degree temperature, but why
not call the compass manufacturer and find out what he fills the compass
with (fluid specs) and if it can stand such a temperature.
Otherwise, if you don't want to go to this effort, just remove it and
store it in the house during the winter.
