Paul, I had my prop train balanced for a special deal of $100, but most
charge around $250 from what I have heard.  It turns out that there was a
fairly high level of imbalance in mine that my seat bottom had apparently
not recognized, vibration level was noticebly reduced afterwards

I had my 182 done and I could not tell the difference. I don't think that
is what Charlie had in mind. Or is it?

No Paul, what I believe Charley is referring to, is a shaking type of test, the
test laboratory sets it up using anything from a crude shaking platform to a
sofisticated ultrasonic set-up depending on the mass/size of the test piece,
and measures the amplitudes.
If you recall, I had the Hub high speed spun tested for balance then shaken (a
la martini) and re-spun again, which passed with flying colors.

BTW butch I got the parts you sent for the dyno. The shaft and two pillow blocks.
Thanks.
