I like to adjust the pin up on the atty so that at first contact the atty is ~1/8th turn from where I want the whole and then snug it down using that last 1/8th turn. you could do the same thing by adjusting the pin till your atty has a tiny gap then snug it flush. Another trick that sometimes works is to set the pin high and then kind of ratchet the atty (twist in/out repeatedly) and the contact will some times adjust itself down in small increments because it's reverse threaded.
And just for clarity, I'm not talking about over tightening the atty on the contact. Once contact is made a very slight additional (that 1/8th turn or less) is enough to make the contact tight.
Edit: that video Tony posted of Hlias using the "ratcheting method" is a great tutorial. Only thing I would add is that some of my Poldiacs wouldn't self adjust like that till after the first time I cleaned the contacts and the threads loosen up a little smoother.
