You did not say what kind of altimeter you have?

It's a Falcon ALT20INF-3, http://www.falcongauge.com/xinjia/ALT20INF-3.jpg

Replace it with a...!

I love the idea of some of these products, but I'd rather redo the entire panel all at once so that I can optimize for space, ergonomics, and redundancy. If I can make this altimeter work just a little more smoothly it would buy me some valuable time.

Here is one place that rebuilds altimeters:

Not sure if rebuilding includes certification (it should).

Personally, I would switch to electronic if I were you. I have a Garmin G5 in my glider and I love the smooth response; you can even use it as a vario.

This replaces about 5 other instruments at a very reasonable cost.
