I've seen the old threads on removing the gauge bezels for glass cleaning and gauge repair. I tried this on my combo gauge and buggered the bezel, although it is still usable. I was wondering if there is an updated technique.
Also, are these bezels available anywhere for sale? I already checked with Palo Alto Speedometer.
Full Version: Gauge Bezel
Ah no, small tool gently pry around the lip. I then take some small pliers with smooth jaws and shape the metal back into proper shape.
Getting them back on, take a hard wood dowel and roll the edge bit over the flange while pushing the cup down on a towel on a solid surface. Gently continue moving the metal gently for best results.
Video on how to do it.
I am sure VDO makes a press to do this. This is how the factories do it now.
But I have an idea for one with replacement rings. LOL, I would need 5 dies and most likely about 25 rings to get it the way I would want it, and then a fixture for a small lever press.
Something similar to these two for installation

And if you have a lathe getting the bezel off is easy, as is installing a different one. But cutting the bezel off is only done when it is stuck hard, or someone has epoxied it onto the can.

Guys - thanks for posting these; a nice reference for those Who Mess With Gauges.
Stephen - particularly impressed with your rotary resealing press design!

@Retrorace Tony thank you. If you have not noticed I have a problem with tools and over engineering solutions. 
To me it is just right.
Version 2.0 I will use a DC lathe motor and spindle to drive it at slow speeds, one lets thing to have to do. LOL.
Thinking about it, I might just build a tool for the lathe, chuck it up, and use the tailstock to apply the pressure keeping everything centered and seated, and add the wheel to tool post . Then I could do it via CNC.
Version 4, see that's how my brain works, and why I redo everything several times.
