Tampy tamp tamp

I bought a broken Nuova Simonelli espresso machine on eBay and fixed it up. Okay, it wasn’t really “broken.” I think the guy who sold it just didn’t care to fix it or understand how the water sensing mechanism worked. It’s caveman stuff (or ultra clever. or both. i can’t decide). There are two terminals on either side of the water spout. If there’s a conductive fluid like non-distilled water between them, the circuit will complete. But the terminals were a bit loose and corroded… so it took a whole 5 minutes to fix.

In the past year, I’ve leveled up my machining skills but I haven’t done much knurling. This seemed like a perfect opportunity to practice by making my own 58mm espresso tamper.
