I have twice tried to repair a compass (with a licensed person
assisting) and both times it ended up costing *MUCH* more than just
buying a new one. It seems to be a very difficult science and the odds
of leaking are very, very high after an OH.



I've had an instrument shop overhaul mine with good luck. First time
was about 9 years ago. The other time was last year, and I'm pretty
sure I did that one in by using an auto sytle heat shield in the window
that put the compass in the little greenhouse created between the glass
and the aluminized mylar bubble material starting about a year before
the compass sprung a leak. Took the guy at the shop less than an hour
to rebuild the compass, including re-wiring the lamp in the compass.
