 Line 5:
- * Type B Past Week Summary
  * Flags and metal prisms ordered; expected 5/31.
  * New assembly drawing [[http://gwdoc.icrr.u-tokyo.ac.jp/cgi-bin/private/DocDB/ShowDocument?docid=5179| D1605179]] focussing on items not part of main chain (and associated screws):
   * Crane adapter
   * Lower breadboard blade module (with cable clamps)
   * IM-RM safety bar ([[http://gwdoc.icrr.u-tokyo.ac.jp/cgi-bin/private/DocDB/ShowDocument?docid=5127| D1605127]] from last week now obsolete)
  * 3D assembly changed to have geophones instead of accelerometers (but SRx will probably be per original design - need to revisit circuit diagram)
  * Concept for load gauge adapter decided (reuse crane adapter plate and jacks from below PI; add Misumi crossbars, cleanroom-compatible chain hoist: [[attachment: Crane Frame.pdf]])
  * Concept for second floor of clean booth decided (remove all floor panels; add bridge panels at right angles: [[attachment:BS Cleanbooth.pdf]])
  * Modified drawings for main assembly frame and drawings for most small parts (jack adapters etc) received from Mirapro.
  * Wire sizes decided: 300 µm piano wire and 500 µm tungsten (will revisit this later).
  * Lots of work on [[http://gwdoc.icrr.u-tokyo.ac.jp/cgi-bin/private/DocDB/ShowDocument?docid=4817| E1604817]] (Fabian; [[https://onedrive.live.com/redir?resid=D5CCFA70A378E0D0!191&authkey=!AMe0pdcd9GDm1H0&ithint=folder%2cwebloc|Draft on OneDrive]]) and [[http://gwdoc.icrr.u-tokyo.ac.jp/cgi-bin/private/DocDB/ShowDocument?docid=4235| E1504235]] (Mark; [[https://onedrive.live.com/redir?resid=D5CCFA70A378E0D0!195&authkey=!AM_usynuo9QI57g&ithint=folder%2cwebloc|Draft on OneDrive]])
