  * Fabian did inventory of parts/fasteners for dummy BS, RM, IM and IRM - almost all at Mitaka. A handful (picos, pico drivers) will be brought back from Kamioka.
  * Fabian continued work on Mathematica and Matlab models of the BS and control system. He now gets much better agreement after correcting discrepancies between the parameter sets.
  * Hirata-san worked on organizing:
   * Checking Mirapro assembly frame drawings
   * Ordering missing screws and small items (screws for dummy mass, fine pitch M8 for RM)
   * Work platforms and clean booth second floor arrangement.
   * Load gauge adapter and associated parts
   * Possible fall-back plans for the rods connecting the security structure to the PI.
   * Design for additional trim masses (existing design had no provision for adding/removing).
  * Mark worked on task lists and schedule.
  * Mark worked on an update of the BS Electronic Items doc ([[http://gwdoc.icrr.u-tokyo.ac.jp/cgi-bin/private/DocDB/ShowDocument?docid=5111|E1505111]]) and started a SRx Electronics Items doc ([[http://gwdoc.icrr.u-tokyo.ac.jp/cgi-bin/private/DocDB/ShowDocument?docid=5886|E1605886]]).
  * Mark worked on an update of the In-Vacuum Cable doc ([[http://gwdoc.icrr.u-tokyo.ac.jp/cgi-bin/private/DocDB/ShowDocument?docid=3901|E1503901]]), including information on lengths that.
  * Fabian worked on a redesign of the EQ stops for the BS (2 of 4 screws under the RM are opposite large holes and there are no screws to restrain the RM front/back at either top or bottom).
  * Hirata-san worked on PR/SR mirror box modifications with Shoda-san.
