Hi Jeff,
	Actually, in this case it was the first iteration of teflon that was  
to blame, the narrow ones without the ridges. Clicks developed  
between them and the wood. Also, at a different point in the humidity  
cycle, excess friction appeared, because the wood could and did  
squeeze the teflon in against the pin. You are right that techs  
didn't have a clue what to do, and screwed things up worse, but the  
original design was flawed. Other things could be and have been said  
about communication and whatnot, and perhaps if they had started out  
with Teflon II (the fatter ones with the ridges), we'd still be  
happily (or unhappily) reaming them, but that's water under the bridge.
