All I want you to do is answer the question.
What do you think that the butt frequency printed on the shaft will
tell you.
How do you find this information useful?
That's all.
It's a simple question, and the same one I've asked you every post -
though you continue to ignore the question.
If you can't answer it that's fine, but it's a simple question.
What do you think this number tells you?
As a shaft designer (and I am one), I would want to know your reason
for this request before I would even consider it.
