At Kamioka (Mark, Ohishi-san, Enzo, Yoshioka-kun, Kozu-kun):
 * We removed the LBB damper rings from the tank and passed them to Takahashi-san for recleaning. Unfortunately two screws galled, one holding on a Cu segment, and one holding on a joint piece.
 * We removed the LBB blade units from the PI, removed the blades and shipped them off for rework.
 * We pulled out all the old in-air cabling.
 * We laid about 9 new in-air cables.
 * We wrapped/labelled the BS mirror box, the winch system, the trolley adapters, and many other tools that we do not expect to use any time soon.
 * We connected up, tested and calibrated the BF LVDT.
 * We adjusted the ballast mass on the IM to make it hang level and at the right height. However we had to reduce the weight by a further 686 g relative to the plan of 2017-08-09. We found a combination that was good except for the fact that it used round masses on the bottom corners, so we decided to have the 641 g rectangular masses cut down by 60 g each. Mesco was able to do this within 24 hours. We will reclean the parts on Friday afternoon and swap them in on Monday.
