  * Fabian worked on IM and dummy BS assembly: [[https://photos.google.com/share/AF1QipMNVSExyP3TuyhK4s_VD-ARDlNoCPCf13ZDbHUlwOw14AKgj4XUe0vYg27dQ12icQ?key=SjJ0dXJ1bjN2OGVCN3d6RnoySEtFSjVJUmVwSlZR|photos1]], [[https://photos.google.com/share/AF1QipPQdoB5vYN1VcD32TkA4QSGldODvKRwiT5h-m122ahSpWmFyyrO5MX-9ajL1LeRIg?key=VFFuUVktcEtlMURQUldhZUlRcGFhbzNDeU5IN3NB|photos2]]
   * A hole in a picomotor holder was too small. ATC staff solved this isue quickly and Hirata-san cleaned the piece.
   * Some ballast discs for the dummy optic were dirty (seen by visual inspection). Hirata-san cleaned them.
   * Some arrows were cleaned from the mirrors for the dummy optic.
  * Hirata-san worked on checking Mirapro's assembly frame design - some minor issues with rail system found.
  * Hirata-san measured another filter.
  * Hirata-san washed a large batch of parts.
  * All parts for gluing of dummy BS are in hand. We arranged with Tatsumi-san to glue magnets at Mitaka on 6/6, glue flags at Kashiwa on 6/8, and inspect bonds and bring dummy BS back to Mitaka 6/13.
  * Mark worked on solutions to allow a [[http://gwwiki.icrr.u-tokyo.ac.jp/JGWwiki/KAGRA/Subgroups/VIS/TypeB/dummyBS|larger mirror on dummy BS]]. After discussions with Simon and Akutsu-san we decided to go with a stainless steel plate solution. The gluing can go ahead and we can attach the plates later.
  * Mark worked on list of items for purchase in FY2016.
  * Mark worked more on [[http://gwdoc.icrr.u-tokyo.ac.jp/cgi-bin/private/DocDB/ShowDocument?docid=4235|E1504235 BS Assembly Procedure]] ([[https://onedrive.live.com/redir?resid=D5CCFA70A378E0D0!195&authkey=!AM_usynuo9QI57g&ithint=folder,webloc|Draft on OneDrive]])
  * Mark and Fabian worked at Kamioka:
   * All the parts for the security structure were located. The clamp pieces for the IM are being taken back to Mitaka to have extra screw holes added.
   * The BS/PR2/SR2 area was cleaned and tidied to allow floor removal and assembly frame construction.
   * 21 "Type 1" cables (PI-Flange, Signal) and 15 "Type 5" cables (OSEM) were tested. They all passed. Sufficient tested "Type 2" cables (PI-Flange, Motor) were located in the PR3 area.
   * Hirata-san worked on the Inventor assembly, adding views (originally defined by Mark) of the different phases of construction.
   * Hirata-san shipped 7 SFs and some parts to Kamioka.
   * Hirata-san made assembly drawings of the damper rings and cable clamps for SR.
   * Hirata-san liaised with Mirapro about the frame assembly.
 * Type B ongoing issues
  * Wires
   * Need to decide RM wire thickness and order BS and RM wires. Lead time is a few days from Nilaco.
  * OSEMs
   * Akutsu-san is working to get wide-mouth OSEMs
  * Longer cables for BF->PI and SF->PI.
   * Takahashi-san has ordered extra connectors (due any day) and will get a company to make the cables.
  * Feedthrough Adapters
   * Need large quantity of male and female D-Sub 9, IDC ribbon connectors - Takahashi-san is getting a quote.
  * Can we make SR wire breakers bigger?
   * Fukushima-san will start on machining test soon (as of 5/27).
  * Installation stuff
   * Crane scale - RECEIVED
  * Ballast masses for payload
   * Initial batch received - ordered extra smaller ones to allow for adjustments.
  * Lower breadboard stuff
   * Installation to be incorporated into the procedure document. Mark/Takahashi to discuss.
   * Breadboard springs (in manufacture, expected end of July)
   * Nail-head parts: quote from Mirapro received, not urgent, will be combined with assembly frame order.
  * 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]]
