TFlan, can I be curmudgeon for a day? I know I won't do nearly as good a job as you but...

...I would be curious what frequency variations you got by varying the clamp pressure around a given pressure of say 50 Lbs. Or something that would be considered a normal FA clamp pressure. Or say the differences from 30 Lbs to 75 Lbs. Just looking for some idea of what the various FA's would demonstrate given their "normal" clamp pressure differences.I sat there for close to a minute, wondering what the hell an "FA" was. Then it hit me: "Frequency Analyzer". What a crock! It's a frequency METER! All it does is return a single number, the frequency at which a shaft is vibrating. That's no "analyzer", it's a meter.
As an EE, I've seen plenty of devices that go by the name "frequency analyzer" and deserve it. In every case, their minimum functionality is to plot a full frequency characteristic of a complex signal or system. By analogy, if a clubmaker's tool did a frequency profile for a shaft, plotting zone frequencies at 1" intervals for the length of the shaft, that would pass for a frequency ANALYZER. But not the products on the market today, no way.
Apparently the folks selling frequency meters are really into verbal aggrandizement. :-P
End of rant.
