Yes Brendan, Al on Al will gall quickly given half a chance (even if it's hard anodized). I also recall burnishing the threads and deburing the thread holes on the ID when I got a set of knobed knobs (CKS). That was another example of less than ideal workmanship, but it's ok, I live to wrench! And I am lucky, working in aerospace most of my life I have access to lots of fun lubricants and such
There is definitely a lot of feel and awareness involved it clutch tightening
