 * Hirata-san produced a near-final Inventor assembly of the BS on the assembly frame, for use in writing the assembly procedure.
  * Includes assembly frame modifications suggested by Mirapro, including feet, wheels, lifting eyes, thicker crossbars under BF, IM etc.
  * Includes final rail system except for interface plate to mirror box.
  * Includes full PI with ballast masses.
  * Includes cable clamps.
  * Includes correct versions of BF and SF.
  * Includes new BF pushrod parts to work around different placement of blade screws in new version of BF.
  * Includes cleanbag support bars.
  * Includes key parts of mirror box (enough to check for interference) - needs more work.
  * Does not include various invisible duplicate assemblies that had been present due to cut and paste.
  * After a few more improvements, the new assembly will be sent back to Mirapro.
 * Got status from Miyakawa-san on electronics - there should be enough of the boxes AEL is supplying.
 * Cleanbag design was finalized; Aso-san is ordering: [[attachment:160419-ﾁｬﾝﾊﾞｰｶﾊﾞｰⅡ型.pdf]]
 * Quote for flags and prisms was received, but expensive - may drop rigid flag design.
 * The mirror box will require only very minor modifications for flags and prisms - Tatsumi-san will arrange immediately.
 * Fabian worked on understanding Sekiguchi-san's control design to help decide optimum wire thickness.
 * Mark worked on install procedure and schedule.
 * Takahashi-san enquired with NIKHEF about oscillator cards for LVDT chassis - lead time would be 3-4 months.

 * Mark glued prisms and magnet/standoff assemblies on the SR3. The SR3 needed to be raised in the box by 0.7 mm to make the prisms go on at the right height, which was done using M4 washers under the PEEK feet.
 * Mark glued ferromagnetic disks on the last 5 IM flags. This completes 2 sets, for SR3 and SRM.
 * Mark configured two pico motor drivers ordered by Takahashi-san as SR3-IM and SRM-BF.
 * Enzo and Kozu-kun finished preparing and calibrating the SF and BF for SR3 and almost entirely finished with those for SRM.
 * Hirata-san worked on building two IMs for SR3 and SRM. The SR3 one just needs to have flags attached and to be weighed; the SRM needs another few hours work.
 * Shoda-san worked on the design of the metal SRM, on the LBB ballast mass, and on the plans for testing the BS in bKAGRA Phase 1.
