They talk about machining, casting, and pressing. Mostly with casting and pressing in a good light, machining not so good.
As somebody who knows absolutely nothing about this stuff, I wonder—casting, I thought, was generally a lower quality option (like cast iron doesn’t have fantastic high-performance material qualities, and I had some crappy cast pewter toys as a kid). Are there different, higher quality casting processes, and I’ve only seen the bargain bin results? Is there a general ranking of the quality of the result or is it all very complicated and material specific?
