I got a Mk IX bubble sextant with an averager 'clockwork' assembly attached and need to open it for cleaning and refill of the bubble, is it safe to remove the right (from the user's perspective) half to get inside?
Generally I am pretty confident with this kind of work as I have repaired a number of old cameras and shutters but am slightly worried some adjustments will be destroyed or way off in the process. Specially I wonder if the averager can be left in place? I imagine some (awkward) calibration may be needed if I jumble too much?
A few tips would be very helpful!
Cheers Micke
