Amazing! I wish I knew more about this stuff to be able to spot a bargain.
I once managed to pick up some camera lenses that I knew would sell for 3 times the price.

AL is a very soft material, which is why speed is recommended for most processes. But chattering is different. It's caused by a harmonic vibration in the bit. Slowing it down helps, but ultimately the only way to prevent it is to use a single flute. Mostly, it's not a critical thing depending on the finished piece. It's a problem with some alloys, like 2024 where water intrusion and mixed metal fasteners can lead to galvanic corrosion, or when riveting. In this example, it's going to be invisible.

Those pictures of the Goldring took me back to the seventies and the Dynatron system we had then. Beautiful work and sounds.
