Funny, I've been playing with panel-meters as well…
I have an analog computer I'm finishing up. I have ADC's to convert the analog to digital to display the values on an LCD (with an ESP32 dev board—it was more flexible than panel meters, cheaper than an oscilloscope).
But because looking at "simulated" panel-meters seemed to kind of undercut the point of the analog computer, I went ahead and created a small PCB to go from my analog computer to a panel meter like the one in the clock.
Running a "Spring + Mass" simulation on the analog computer and seeing both the LCD/ESP32 representation of a panel meter and an actual panel meter move in sync brought it all home.
If there's a makerspace or hackerspace near you, they might have a CNC router. Apart from (I believe) the front panel being a two-sided job, this is pretty straightforward and could be done entirely on a Shopbot or equivalent. Worst case you might need to learn FreeCAD and buy some collets ($10-$50) and bits (~$50-$75 if you're getting two). Best case, they have software and tooling you can use.

Edited to add: if you skip the rabbets around the gauges on the front panel, you can make that a single-sided CNC job, which makes it much easier. With some care, you could do those with a handheld router and a rabbetting bit.
You’re exactly right..that’s how I end up learning tech stuff. It’s not working very well with modelling though. I’ve set my sights too high, the projects are too involved
Ways to keep more than one brain center active!

(nor would the missus be pleased for me to buy them - but that's another matter)

is 10Hz control just too slow?
