So sexy! I could probably build the electronics easily enough, but such projects need workworking tools I just don't have room for in my tiny flat.

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

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.

Source: am a furniture maker professionally. Have worked out of a makerspace, and have done equivalently complex projects on their Shopbot.

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.
