I should add that the panel is cut for an 80 mm diameter instrument.
No flask is needed, as a serviceable one is already mounted in the glider.

Further to my last post on this topic, it now seems that the vario I had
"repaired" at Independent Instruments is stuffed (technical term). The
original problem was just a zero error, which I was loth to fix myself,
as it was not easy to remove the glass to get at the movement. The error
seemed to be a balance one, rather than a spring setting.
When I got the vario back from Independent Instruments, it was reading
zero OK, but was entirely dependent on gravity for the restoration
force. When I took it back to them, they maintained that there was no
hairspring in such instruments, and that gravity was always used as the
restoring force. I had my doubts, but, not having any qualifications in
the instrumentation area, I felt I couldn't argue. Now that the
instrument is mounted in the glider and a test flight done, we have
determined that the vario doesn't work.
I know I should take it back and complain, but I would rather just get a
replacement and forget the whole mess.
Does anyone have a secondhand working Winter Variometer for sale please?
I don't want to fit a modern electronic vario, as the glider is a
Bergfalke II-55, which would have been fitted originally with a
mechanical vario.

Thanks for that Ian.
I don't know, but I suspect that Independent Instruments may be under
new management, as I didn't see the old gentleman and lady there on
any of my four visits over the last couple of weeks.
They always gave great service, but I am not sure the current lot have
the same dedication to quality.
Cheers, John G.

Good question John,
We had the same experience. I was going to send my ASIs' to Adelaide
but it is actually cheaper to buy a new one from Wade Air in NSW. I'm
not sure about the other instruments.
The big question is just how old are the instruments?
I am slowly replacing mine with new ones.

Hi All in Victoria,
Where do people go for repair/calibration of instruments such as
ASIs, Varios, Altimeters etc. ?
I have been using Independent Instruments at Moorabbin, but my last
experience has not been entirely happy, and I would like another
possibility...
Cheers, John G.
