Latest update!
First a clarification...when I said Sue told me a resounding NO to my working on the issue, that wasn't meant in a bad way, in fact, she is saving me from screwing something up which is a good thing! She was very helpful in explaining why I didn't want to take that part of the headstock apart on my own.
Princess? Haven't been called that in a long time!

I probably wouldn't have noticed it except I can run A/B comparisons with the old head stock and one vibrates the other doesn't. (Ok, maybe not as bad as a real jackhammer

Shouldn't do this when I'm ticked off! Mea culpa)
Yup, have waxed it twice including the gear teeth on the bottom side. Didn't really change anything.
As for wearing in the parts, I did have to do that with my BMW motorcycles...600 miles then change the oil, then good to go forever with regular oil changes but have never had to do that with power tools. So maybe that's the deal, I just need to use it a bunch and see if things straighten out.
I did receive a call from SS, they have been reading the forum (Big Brother...good for them, that's the right way to use a forum) and they want me to send it back again. I didn't get a chance to return the call but will do so on Monday.
Have mixed feelings about sending it back yet again. First off, it's not an easy job for me to take it off, pack it and get it up the stairs. I'm not able to lift that much weight any more so I have to get help. But more importantly, what's going to be different this time? If that was as good as it's going to get and nothing is being harmed internally, what do I gain? If I was SS, I'd just ship me a new headstock in exchange for this one and use this one for learning purposes in the lab. Gotta be cheaper than shipping this thing back and forth and working it.
I'm thankful that they are willing to continue to work on this but will wait until I can talk to SS again and see what they think they can do. With the holidays, etc. I'm assuming I'll be without my headstock for at least another 3 weeks or so.
