Hi Kevin and others interested

I am the guy with the vibration analyzer and I must admit that I got
 sidetracked with job and school issues.  I am finishing my masters
 degree
 and will be processing the data for my thesis so I should have
 something to present sometime in June but I am not ready to publish
 that
 information until I have it peer reviewed.  I did have a problem in
 determining the RPM due to a bad design for the tach pickup (my bad),
 but I
 have rectified that issue and when I can start data logging and
 producing
 reports I will let every one know.

If you wish to see a sample (hard to understand) here is a link

look under Vibrational Analysis Data / Joe Horton.  I am designing more
 meaningful reports to go along with the graphs but they probably will
 not be ready until after June due to workload and completing my
 thesis.

Best regards to all
