  * Fabian finished dummy BS assembly.
  * Mark and Tatsumi-san glued magnets into both types of BS optic flags, and discs into BS IM flags. [[http://klog.icrr.u-tokyo.ac.jp/osl/?r=1815 |klog]] Two optic flags had to be redone because the magnets moved while the glue was drying. Hirata-san helped remove the magnets with acetone in the ultrasonic cleaner. [[http://klog.icrr.u-tokyo.ac.jp/osl/?r=1818|klog]]
  * Tatsumi-san, Fabian and Mark took the dummy BS to Kashiwa and glued the flags and prisms. [[http://klog.icrr.u-tokyo.ac.jp/osl/?r=1821|klog]] We will check status on Mon 6/13.
  * Hirata-san measured another filter.
  * Hirata-san washed a batch of parts.
  * Hirata-san worked on work platforms for the installation.
  * Hirata-san looked for a crane scale for use at the site. (We decided the 500 kg version of the one used at TAMA.)
  * Hirata-san worked on making some guide parts for the PI installation (Misumi parts with minor additional machining from ATC).
  * We finalized a design for simple SS mirror parts for the dummy BS with Akutsu-san. They will be made by ATC.
  * Mark worked on list of items for purchase in FY2016 and on the schedule.
  * Fabian did more work on the IM assembly. It is nearly done and he will start on the RM next week.
 * Type B ongoing issues
  * Wires
   * Need to decide RM wire thickness and order. Lead time is a few days from Nilaco.
  * Can we make SR wire breakers bigger?
   * Fukushima-san will start on machining test soon (as of 5/27).
  * Not enough crane height problem (Hirata, Saito) - no action since last week
  * Ballast masses for payload
   * Initial batch received - ordered extra smaller ones to allow for adjustments.
  * Lower breadboard stuff
   * '''Need to be incorporated into the procedure document. Discuss with Takahashi (Mark)'''
   * Breadboard springs (in manufacture, expected end of July)
   * Nail-head parts: quote from Mirapro received, not urgent, will be combined with assembly frame order.
  * Clean bag - expected 6/8.
  * Documents
   * 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 and Hirata-san at Mitaka
   * Gathered parts for cable making.
  * Mark and Hirata-san at Kamioka:
   * Replaced the floor panels that had been taken from the PR2 area (filling in the hole in the floor) and found/installed two new panels to act as bridges near the BS assembly frame.
   * Installed two more LPCDs and the stepper motor driver in the PR2 rack.
   * Ran cables from the rack to the second and third sat amps (for the IRM OSEMs).
   * Added a second DIO card in the rack and connected it to the BIO inputs and outputs of the new LPCDs.
   * Started making extension cables for RM-H2 and -H3 OSEMs but gave up due to complicated grounding arrangement.
   * Washed four 40-cm D-Sub-9 ribbon cables to use as temporary extensions (maybe also for H1/H4).
   * Added extension to the IM pico cable for the BF yaw pico.
   * Made LVDT adapter cable.
  * Mark worked on schedule.
