Slack in Floyd Rose arm

Ah. My bum arm screwed down just fine and stayed down, but the arm had wobble before it moved the trem.

After experimenting, it seems that it is not so much the threads in the collar, but the actual thickness of the bar itself that goes into the bushing. Teflon tape does not resolve the issue on the threads. The threads make a strong solid connection as is, even tightened all the way does not help, there is play/wobble in the arm prior to the trem moving. So basically, out of three OFR systems, I have one arm that works perfectly on all of them.
