After several hardware hunting excursions, the ETMy sleeve is mostly installed.  With the TMS crew eager to begin their work, and one more excursion remaining, I left the TMS crew to do what they had to do.  Since their work involved using the Genie (which I had not known about prior), I decided to postpone installing the vibration absorbers as well, since they are yet another access limiter/head knocker and they are very quick to install.  NOTE FOR THE TESTERS: the ETM is still locked and probably will remain so until after SEI has finished balancing and floating.
