-  * Fabian, Mark, Yokogawa-kun and Kuwahara-kun did BS installation at Kamioka:
   * Calculated BS pitch correction ([[http://gwdoc.icrr.u-tokyo.ac.jp/cgi-bin/private/DocDB/ShowDocument?docid=5630|JGW-T1605630]])
   * Hung dummy optic and set pitch.
   * Prepared RM for hanging (adding OSEMs etc). One OSEM (#24) had wobbly leads and was brought back to Mitaka for rework.
   * Placed vacuum feedthroughs on assembly frame and cleaned initial batch (4) of D-Sub cables.
   * Decided position of BS rack with Miyakawa-san.
   * Measured various maraging rods and the rod holders on the SF.
   * Placed safety rails, rearranged floor panels, cleaned new floor panels, and otherwise improved safety.
  * Hirata-san:
   * Made new 3D models of the maraging rods for PRx and SRx
   * Made new collet design for PRx and SRx (3D and 2D).
   * Made new IM flag design for PRx and SRx (3D and 2D).
   * Washed lots of Type A BF parts and OSEM parts.
   * Cleaned the BS BF-IM maraging rod and organized the rest of the stock of rods.
   * Measured some BF part dimensions.
   * Pre-assembled parts for BFs.
 * Type B ongoing issues
 * Longer term to-do list
  * Do Inventor assembly for SR2 in chamber and on assembly frame (Hirata) - NEARLY DONE.
   * Part "disk security" top has to be modified - screw positions do not match.
  * Write more of payload assembly procedure (Fabian) - ONGOING
  * Write more of BS Assembly Procedure [[http://gwdoc.icrr.u-tokyo.ac.jp/cgi-bin/private/DocDB/ShowDocument?docid=4235| E1504235]], [[https://onedrive.live.com/redir?resid=D5CCFA70A378E0D0!195&authkey=!AM_usynuo9QI57g&ithint=folder,webloc|E1504235 draft]] (Mark) - ONGOING
  * Lower breadboard installation to be incorporated into the procedure document.
  * Work on BS simulation (Fabian)
  * Do BS Simulink model (Mark, Kokeyama)
  * Do 2D drawings of SR2 parts (Hirata)
  * Redesign SRx IM wire clamps for larger prisms, remachined RMs
  * Order SRM/PRM parts  (Hirata/Shoda)
  * Order SRx fasteners (Hirata)
+  * Mark worked on task lists and schedule.
