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.
At Mitaka (Hirata-san:
 * Hirata-san got a quotation about optical bench from Mirapro and contacted them about reducing cost.
 * He asked Suzuki-san (Tokyo university) to order them (delivery date is 10/24, so far).
 * He modified SR assembly frame design (from Fabian) and asked Mirapro for quotation.
 * He liaised with Koshin-shoko about modification of BS LBB blade springs.
 * He asked ATC for making t4.5 ballast mass for PR. He washed them and sent them to Kamioka with the PR thrust bearing.
 * He worked on the 3D model of SR3 SUS wires, and making a list for quotation.		  * Mark created screens and a macro.txt file for the SR2 and linked to them from the VIS screen.
 * Enzo and Mark did a new overview screen for the BS.
 * Enzo added DIO cards to the rack and connected them to the coil drivers.
 * Fabian and Kozu-kun finished assembling the IM and tested the picos over their full range.
 * Mark and Hirata-san configured and aligned the assembly frame and optical table and craned in the IM ring.
 * Hirata-san noticed some oxidization on several of the L-brackets that will hold the IM horizontally, and we should get them cleaned or machined, but we can probably continue with hanging the system in the meantime.

 * Swap in new IM ballast masses; readjust height and levelness.
 * Install side panels of IRM and OSEMs.
 * Route IRM OSEM cables, test/adjust IRM OSEMs.
 * Add BF cap; cable and test BF-1 and BF-2 picos.
