Josh, I did not see your question until now.
I did not find anything unusual with the ball mill ODS. I was looking for loose bolted joints and fractures at concrete pour joints.
I have reposted the movie. The movie in my original post was corrupted and did not play completely. Also included in the zip file is another ODS of a different ball mill that had a concrete fracture as well as loose or stretched bolts below the pinion bearing.
Call if I can help.
