yet another trem bar question

[bluffalo]

How tight should the spring screw be?

and

how "tight" is your trem arm holder? when you hold the bar lightly and move quickly up and down, do you hear any noise? any ticking or thudding? is it totally silent and no "play" at all?


ive already broken one arm holder, but on my other mint condition 550 reissue the bar is slightly loose on that one too. (i broke the 7620's tightening and loosening it)

the (brand new) bar on my 550 is just starting to show wear above where the nylon washers are, on the forwards and backwards area (as in, diving and pullups, theres no where on the sides obviously) becuase of the slight amount of play causing the bar to move in the socket, rubbing the finish off.
